Let There Be Light

Strategically placed windows and doors can increase the amount of natural light entering your home and dramatically change the home’s look, feel, and ambiance.

Who wouldn’t want more natural light in their home? With improvements to health and well-being and enhanced ambiance in the home – you wouldn’t find many people saying no. Some of the other benefits of increasing the natural light in your home include:

• Increases in energy efficiency
• Improved ambiance and increase in room size
• Increase in the value of the home

Health & well-being

Natural light has a positive effect on our health and well-being. Increasing the amount of natural light that enters a room creates comfortable living spaces and improves the mental health and productivity of the home’s occupants.

Energy efficiency

Increasing natural light also goes a long way in increasing your home’s energy efficiency. Installing energy efficient windows, such as the Darley CityView and ClimateGuard sliding, awning, and double hung windows, helps with this process by keeping the cold out in winter and the heat out in summer. Thereby reducing the homeowners’ reliance on air conditioning & other types of artificial temperature control and reducing their energy bills.

Increases room size

Natural light positively affects any environment by enhancing a room’s ambiance and giving the perception of increased space – making smaller rooms appear larger than they actually are. Perfectly illustrated with these series of project photos:

Increase the value of your home

In addition to increasing the perceived size of a room, increasing natural light also increases your home’s value. How, you ask? Increases in natural light make a room appear more inviting and spacious. The enhanced natural light can also highlight the home’s architectural features, creating a strong first impression and an increased perceived value by the buyer or potential renter. There are many ways to increase the amount of natural light that enters your home, including:

• Installing sliding doors
• Installing sliding or awning windows in the kitchen
• Installing glass doors
• Installing commercial framing combined with other types of window systems
• Exploring ClimateGuard thermally-broken window and door systems
• Investigating different types of glass

Installing sliding doors

Installing wide panel sliding or stacking doors into your living areas and combing them with your outdoor spaces increases natural light, room size and also creates an additional entertainment area.

Installing awning windows in the kitchen

They say the kitchen is the heart of the home, where families come together, prepare meals and entertain. Adding a servery or awning window in the kitchen, behind a sink or bench, can significantly increase the amount of natural light entering the room. A servery window is typically installed between a kitchen and outdoor living area and facilitates the easy transfer of food and drinks between both areas. Gaining popularity in residential homes with patios and entertainment areas, servery windows are easy to install and integrate indoor and outdoor living areas seamlessly.

Installing hinged door or French doors

Installing glass hinged doors or french doors instead of timber doors is a great way to increase natural light in your home. Not only do they offer uninterrupted views
of your outdoor spaces, but they are also compatible with other aluminium window systems. For example, the CityView 45mm commercial door seamlessly integrates with other CityView window systems and commercial framing systems. While a set of French doors can increase natural light and improve the aesthetics of your home and be customised via finishes & configurations to match your taste and the style of your home.

ClimateGuard thermally-broken window and door systems

When discussing energy efficiency in Australia – you can’t go past the existing NatHERs requirements. In Australia, Architects and designers must adhere to the NatHERs (National House Energy Rating Scheme) star rating to measure the energy efficiency of a residential home. Homes must meet a minimum 7-star rating for occupancy – there are several options when it comes to reducing your energy efficiency rating. Installing effective insulation in the form of batts installed in roofs and ceilings can have a significant effect on achieving the minimum rating. As will installing effective window systems with improved glazing options and increased thermal comfort. Darley’s ClimateGuard window and door systems are made with thermal-break technology that increases energy efficiency, resulting in a lowerthan- average u values of 2.5 and below. Architects and designers are under increasing pressure from not only homeowners, but stakeholders in commercial projects – who want to install the maximum number of windows and doors while still staying within the limits of government regulations for energy efficiency, WERs ratings, and u-values. The performance of a window is measured via its u-values – the lower the u-value, the greater the window’s insulating properties. U values can vary greatly – a single-glazed residential window system has an average u-value rating of 8, while the u-value for the Climateguard thermally broken Architectural Sliding Door is 2.5 Great news for architects – they can install several ClimateGuard window and door systems into the premises and stay within the limits of government regulations.

Installing commercial framing combined with other window systems

When you think of commercial framing, you tend to think of high-rise apartments and large-scale projects, but did you know installing commercial framing with aluminium window systems can have a massive impact on increasing natural light? For example, combing a commercial framing system with a double-hung window or an awning window can increase the amount of natural light and the room’s size, as shown by these project photos. Commercial framing systems provide a number of benefits to architects & designers, including design flexibility, structural integrity, and the freedom to create open floor plans. Architects have the ability to integrate a range of different design styles, including traditional or contemporary, with the use of commercial framing. Open floor plans and creating functional spaces are all a possibility with commercial framing, whether it be for residential or commercial projects, and can be easily modified for future changes in the building layout.

Explore different types of glass

Different types of glass impact the amount of natural light that enters a room. For example, Low-E (low emissivity) coated glass is designed to reflect heat and allow light to pass through it. Thereby keeping your home warm in the winter (and cool in the summer) and still allowing natural light to enter. There are two types of Low-E coatings: Hard coated low-e and Soft coated low-e. The hard coat low-e is when the coating applied to the glass in the furnace during the manufacturing process, with the coating fusing onto the glass as it cools down. This type of coating is great for energy efficiency as it is installed in the interior of the building to regulate indoor temperatures and reflect the heat or cold back into the room. One of the disadvantages of using this type of coating is the fact that it can create a haze effect
– which can be visible in certain daylight conditions.

The soft low-e coating works differently with the coating applied to the glass after it has gone through the manufacturing process and cooled down. This type of coating must be enclosed in a double glazed unit, making it last longer and perform better, and increase energy efficiency. The downside to applying the soft coat low-e to glass is that it does need to be installed by a qualified glazier or window installer in a specific way to function correctly. The good news is that Darley’s CityView, KlassicView, and ClimateGuard window and door systems are versatile and can accommodate the above glass types and a range of others with varying thickness levels.

Don’t forget about the bathroom & laundry

There is a allot of discussion around light exposure in the kitchen and other frequently used living areas but what about other areas, such as bathrooms and laundries? A great way to increase natural light in your bathroom or laundry is by installing aluminium louvre windows. Not only do they look good, but they also increase natural airflow and ventilation. Facilitating adequate ventilation in the bathroom or laundry is just as important as increasing natural light. The Darley Ventient Trickle Ventilation system ticks all the boxes when it comes to natural airflow and ventilation. It is energy efficient and, requires no power to operate, conveniently fits into window systems – passively circulating airflow according to changes in ambient temperature.

Important factors to consider when selecting windows & doors for Aged Care facilities

In our retirement years, we hope to relax, catch up with old friends, pick up new interests and hobbies and be comfortable in our surroundings.
Some of us will want to live at home, while some will prefer to go to an aged care facility. Over the last 10 -15 years there has been an increase in our aging population Australia-wide. With this increase comes increased pressure on support services and a greater need for aged care facilities. Unlike other commercial projects, aged care facilities must be built according to stringent requirements to accommodate the specific needs of its elderly residents and ensure their comfort and safety. Architects and designers are under increasing pressure to design facilities that are functional but also easy to navigate, safe, and allow residents a certain level of independence.

The National Construction Code (NCC) sets out the requirements for access and egress provisions in all new buildings. The NCC references AS1428.1-2021 Design for Access and Mobility – which outlines the minimum design requirements for new building works and provides guidelines for elements including continuous path of travel, door openings, communal living spaces, threshold ramps, visual indicators, and many more elements.

There are several factors that impact the selection of window and door systems for aged care facilities, including:
• Accessible paths
• Air Ventilation
• Ease of operation
• Acoustics -Flyscreens
• Bushfire ratings

Accessible Paths

Under the aged care requirements set out in AS1428.1-2021 – a continuous and uninterrupted path of travel must be provided in all aged care facilities.
Thresholds Where possible thresholds at doorways should be eliminated. A flush threshold between internal and external environments is an important feature in complying with the standard. By including a flush sill in the sliding door system, not only does it provide wheelchair access but also reduces the risk of potential trips and falls by elderly residents. Darley’s new flush drain sumps (TJ400 & TJ600) and new flush sill (SD408 & SD608), can provide the solution – log onto the online customer portal https://darleyaluminium.com.au/ to view the product bulletins.

Air Ventilation

The recent covid outbreak has made us more conscious of providing our elderly residents with good ventilation and air quality. A large number of aged care residents spend a great deal of their days indoors and providing access to operable windows is not always a possibility, especially for residents with dementia. Air purifiers have been installed in a number of facilities to increase natural flow and maintain optimum air quality. Another practical option is installing louvre windows. Easy for residents to operate, with a modern aesthetic that comes in a range of colours and styles. Louvre windows can be installed as a fixed window system or motorised. Another solution for maintaining air quality is to install a passive trickle ventilation system. Darley’s Ventient – trickle ventilation system is a low-cost, energy-efficient option that is perfect for aged care facilities. A trickle vent is a small opening in a building envelope component, that allows small amounts of fresh air in spaces when major elements of design, like windows or doors are otherwise closed.

Ease of Operation

When selecting window and door systems for aged care facilities, operability is an important consideration. Opening a sliding door or a double hung window may seem like an easy task, but for a resident with arthritis and coordination issues, it can be quite a difficult task. Hardware also plays an important part with regard to the operability of windows and doors. Installing door handles and hardware that can be unlocked and opened with one hand is recommended. ‘D’ pull handles, and lever handles are suitable options and are required to be installed onto sliding doors to accommodate elderly and disabled residents. According to the requirements of AS1428.1-2021, the clearance between the handles and the back plate must not be less than 35mm and not more than 45mm. Darley has a number of compliant door handles available , from well known hardware brands including Allegion, Brio, ASSA ABLOY and Anthony Innovations.

Acoustics

The last thing residents in an aged care facility need are the interference of outside noise. Installing window and door systems with superior soundproofing is of high importance. The sound reduction performance of an aluminium window or door system is measured in Rw. Darley has tested the acoustics performance of a number of residential, commercial, and framing systems; Click here to view an article with all the ratings. The CityView, HarbourView, and commercial framing systems all provide adequate soundproofing in aged care facilities and comply with the requirements set out in the BCA.

Flyscreens

Architects and designers need to ensure there is adequate circulation spaces in communal living environments. These spaces, where elderly residents congregate, need to maximise natural light and ventilation throughout the aged care facility. Under the BCA, all operable windows must be fitted with flyscreens to facilitate natural air flow and also protect against insects and vermin. Darley’s CityView and KlassicView ranges can all be fitted with flyscreens providing ventilation and integrating seamlessly with these residential and commercial, window & door systems.

Bushfire Ratings

Often aged care facilities are built in bushfire prone locations, therefore making it critical for developers and builders to install bushfire rated window and door systems. Several window and door systems in our CityView commercial range are BAL40 rated – Click here to find out more.

As you can see, Darley offers a range of window and door systems that cater to the specific needs of older residents. Whether it be flyscreens that provide increased airflow and ventilation or flush sills & drain sumps for flush thresholds – Darley provides the complete solution when it comes to window and door systems for aged care facilities

Keeping the kids safe this summer holidays

Summer is just around the corner, and so is the risk of children suffering serious injury from accidental falls from windows and balconies.

You may be surprised to hear that nearly all accidental child falls from windows and balconies occur in the family home. Quite frequently these easily preventable falls result in serious injury, admission to hospital, and even death. Most of these incidences occur during the summer months when parents tend to leave windows and doors open to combat the heat.

In 2013, the Building code of Australia (BCA) was updated to include regulations for windows and balustrades to reduce the risk of child death or injury from accidental falls.
The BCA stipulates a maximum opening of 12.5cm or less for windows and balustrades above the ground floor. All windows must be fitted with a device or guard, such as buffer stops, restricted latches, locks, and restricted opening chain winders, that restricts it opening beyond 12.5cm.

Flyscreens
There are some practical solutions for preventing accidental falls from windows such as keeping
beds and furniture away from windows, ensuring children are always supervised and not replying on flyscreens for fall prevention. A child can fall out of a window (with an opening of 12.5cm or more), even if the window has been fitted with a flyscreen. Great for letting cool breezes in during the summer but not a suitable option to prevent a child from falling from a window.

Security screens and fall prevention
A typical flyscreen may be a no-go but some security screens, made from 316 marine grade mesh, can be used as a solution for fall prevention.

The ScreenGuard stainless steel mesh security system is made from 316 stainless steel mesh and high-quality aluminium frames that are T6 tempered. The unique rib design of the ScreenGuard system means that when installed according to the requirements of AS5039, it creates a significant barrier making it resistant to mesh removal by intruders and the impact of a child falling out of a window.

So not only does the ScreenGuard security system provide protection against accidental falls, it also offers the added benefit of increased air circulation and ventilation during the warmer months, without obscuring the outside view.

Performance & testing by a NATA accredited laboratory
Over the last couple of years, there have been a number of campaigns targeting families and the community to raise awareness of this child safety issue.
But ever wondered what guidelines and testing have been applied to these window restriction devices to ensure the child’s safety?

The Australian Standard AS5203:2016 for the protection of openable windows / fall prevention test sequence and compliance methods is the key standard, that was published in 2016, and outlines the test methodology for windows fitted with fall prevention devices; such as window restrictors or security screens.

These standards, not only stipulate that the maximum window opening of 12.5cm but also that the devices must be able to resist an outward horizontal force of 250N for 10 seconds, against the window being restrained by the device or screen.

These tests are carried out by a NATA accredited laboratory, that uses specialised equipment to determine if these window restriction devices meet the requirements of the Australian Standard. One of which includes a 125mm child head-shaped object, that is used to test the most vulnerable point of the window.

The Azuma testing facility in Wetherill Park NSW, is a NATA and SAI accredited laboratory that provides a wide range of tests for Australian Standards including AS5203:2016.
The Darley window systems listed below all meet AS5203:2016 requirements with regards to child fall prevention:

-ScreenGuard Stainless Steel Window Screen
-KlassicView Sliding Window
-KlassicView Awning & Casement Window
-KlassicView Louvre Window

The above-listed window systems have been tested at the Azuma testing facility and satisfy the requirements of AS5023:2016 for the protection of openable windows.
Meaning homeowners can rest assured that these window systems provide a solution to child fall prevention, keeping the kids now and for years to come.

New name and upgrade put the CityView Architectural Sliding Door & ClimateGuard Architectural Sliding Door ahead of the rest

More than just a sliding door, Darley’s new sliding doors tick all the boxes for compliance and high performance.

There are not many aluminium window and door fabricators, who have not used the CityView Apartment Sliding Door system over the years. This popular sliding door system has been used by countless builders and developers and installed in some of the most prominent commercial and residential buildings in the country.

This year has seen some exciting changes to the Darley Aluminium product line with the upgrade of some of our existing products. Two of our most popular door systems, the CityView Apartment Door system, and the ClimateGuard Apartment Door system, have been given a new name to better match, and highlight, what these products represent.

Now known as the ClimateGuard Architectural Sliding Door system and the CityView Architectural Sliding Door system, these new and improved product lines will appeal to a much wider audience in both commercial and architectural applications. These systems are widely used in high-rise multi-residential dwellings, with the ClimateGuard (thermally-broken) Architectural sliding door becoming increasingly popular in architectural, residential, and commercial projects.

Some of the main upgrades to these Architectural sliding door systems include the addition of new flush sills and flush drain sumps, the introduction of large stiles to suit a variety of mortice lock options, and the CityView Architectural sliding door achieving a BAL40 bushfire rating.

There has been a favourable response from Darley’s customers already using these systems, and they are pleased that the rebrand more accurately suits the product’s capabilities. The recent Petersham RSL upgrade, saw the CityView Architectural sliding door installed in the Siding apartments by NSW fabricator: Style Windows & Doors Pty Ltd. (Click here to find out more)

NSW fabricator: Trio Designs installed the thermally-broken ClimateGuard Architectural sliding door into a newly renovated, modern residential home in Dover Heights NSW, with the owners of this coastal property reaping the benefits of increased energy efficiency and protection from harsh weather. (click here to find out more)

Darley Aluminium National Sales Manager, Ray Kwan said, “We identified that our CityView sliding door and ClimateGuard sliding door systems are being widely used across the full spectrum of residential, multi-residential, commercial, and architectural construction, and therefore felt that rebranding the systems to better reflect their use in the marketplace. As part of the rebrand, we’ve also introduced the flush sill and integrated flush sub-sills for flat threshold transitions, and also completed testing for the new systems including AS2047 for windows and external glazed doors in building and AS3959 for construction of buildings in bushfire-prone areas.”

New flush sills and flush drain sumps
Both the CityView and ClimateGuard Architectural Sliding Door systems now feature new flush door sills (SD408 and SD608). Designed and engineered in Australia, these flush sills are aesthetically pleasing, practical, and self-draining. They are disability access compliant making them the perfect choice for the aged care sector. They are also pre-slotted, so there is no need for additional fabrication, and are tested to Australian standard AS2047.

Another feature added to both the CityView and ClimateGuard Architectural sliding door systems are the new flush drain sumps (TJ400 and TJ600). These unique one-piece sumps, which are also designed and engineered in Australia, come pre-slotted, so there is no additional drilling or notching required by the fabricators. The new flush drain sumps are also suitable for all sliding and folding 100/101.6mm and150/152.4mm operable systems and will suit any 25mm and 65mm stainless steel grate.

CityView Architectural Sliding Door rated for BAL40
Earlier this year, the CityView Architectural sliding door system was tested to the updated and more stringent standard AS1530.8.1-2018 to BAL40, which is the highest bushfire rating available in Australia before BAL-FZ (Flame zone). Testing was conducted by NATA accredited testing organisation: Warrington Fire, in accordance with the requirements outlined in the current 2018 version of the testing standard.

To simulate more accurate fire conditions, Tasmanian Oak was used during testing instead of the traditional pine cribs, which results in higher burn temperatures. The system exceeded testing requirements and was able to withstand temperatures of up to 40 kW/m2 without compromising the frame and glazing components. BAL40 is primarily concerned with the protection of buildings from ember attack and burning debris ignited by wind-borne embers and exposure to a high level of radiant heat.

New stiles to suit mortice locks
Another exciting upgrade to the systems is the new stiles (SD148, SD162 & SD172) that can accommodate a variety of mortice lock options. As with the other new features, the new stiles can accommodate a wide range of hardware options and key functions, including residential and commercial mortice locks, pull handles, surfaced mounted options and flush pulls.

These systems not only integrate with current design trends but rate highly with regards to performance specifications. Both the CityView Architectural Sliding Door system and ClimateGuard Sliding door systems are versatile and can be incorporated into a variety of configurations by using the common Darley commercial framing systems. They are also able to accept single or double glazing options, allowing for the flexibility to meet all budgets, whilst adhering to stringent energy efficiency requirements.

Not all doors are equal

It’s surprising to see how many people are unsure whether the door they have chosen is a barrier screen door or a security screen door. There are several types of screen doors on the market and it’s important to understand what your needs are and what the different doors can provide.

Screen doors and window screens are a common feature of construction in most parts of Australia, allowing for free circulation of air in hot weather and protection from insects and pests; however, flyscreens offer little security and are easily broken through. So it is important, that the first thing you consider, is whether you need a door to simply keep the insects out and the fresh air circulating, or whether you want safety and protection from intruders.

For example, a simple fly screen door is considered a barrier door and provides protection from insects but has no place as a security door to protect against break-ins. When it comes to home security, the door is often your first line of defence, but if not chosen correctly, it can turn out to be the weakest link.

image presents not all doors are equal

For doors to be classed as true security screen doors they must meet the requirements of stringent Australian Standards and demonstrate they will withstand attempts at forced entry. The three key Australian Standards are:

  • AS 5039-2008: Security screen doors and security window grilles
  • AS 5040-2003: Installation of security screen doors and window grilles
  • AS 5041-2003: Methods of test – Security screen doors and window grilles

Darley Aluminium National Sales Manager: Ray Kwan said, “The standards mentioned above set out the requirements for security screen door design, testing and performance. The standards are in place to make sure the doors are designed and built to withstand forced entry. These standards also demand that security screen doors are correctly installed to reduce the risk of them being removed completely or tampered with and in some states and territories, the installer and/or security screen provider must hold a building or security license to install security screen products in your home”.

Some flyscreen doors which feature bars or grilles often give the appearance of providing home security and while they may, on occasion, act as a visual deterrent, many will be easily penetrated by an intruder.

When we talk about these doors being able to withstand forced entry by an intruder, they must pass a series of tests to meet AS 5039-2008. These tests include:

The Knife Sheer Test – simulates a knife attack on your security screen

The Impact Test – designed to stimulate an intruder trying to kick their way through a security door or window

The Anti-jemmy Test – designed to simulate an intruder using a lever to get past the security door or window

The Pull Test – stimulate an intruder trying to pull out a security screen

The Probe Test – simulates an intruder, having created a gap and trying to get their hand inside to unlock a door or window

According to CHOICE, many doors don’t meet the standards, : Unfortunately, in most states, a product advertised as a “security screen door” may only secure you against flies: the term is meaningless unless the door can be shown to meet Australian Standard AS5039-2008. There’s also a standard for installation (AS5040), and you should ask the installation company for a written guarantee that its work complies”.

Other things to consider when choosing a screen door, or window, include:

Visual impacts
As mentioned above you will need to consider whether you would like grills or be free from obstructions. You will also need to consider how the design will impact the amount of light and air coming through.

Suitability for your location
Buildings located close to our Coastline should consider security screens that will provide the best defence against the elements. The Australian climate is particularly harsh, with extreme heat and at times, turbulent winds, which can cause corrosion. While you want to choose a security screen door that will protect you against pests and the elements, you’ll also want a security screen door that can withstand our harsh climate. Darley’s ScreenGuard system is well suited to these climatic conditions using corrosion resistant 316 stainless steel mesh.

Fall prevention
The National Construction Code (NCC) specifies various requirements for the prevention of falls from openable windows. The aim is to limit the risk of a young child or other person falling through an openable window divided into two categories:

1. A fixed device attached to the openable part of a window, or

2. A fixed screen across the openable part of the window, or

Simple flyscreens do not prevent potential falls from multi-story windows. A security screen system such as Screenguard should have been tested for impact and force and will prevent the possibility of small children from potential falls These security screens still offer the same ventilation and insect protection as other screens.

Locking systems and installation
A standard flyscreen is unlikely to require a force-resistant locking system. Tested security screen doors must include a suitable 3-point locking system which can withstand forced entry. Secure non-removable hinges should be in place and the overall design should offer a strong frame.

Looks
Choosing a full security door doesn’t mean you have to compromise on looks. For example, ScreenGuard Stainless Steel Security Mesh means you no longer require unsightly grilles and bars to produce a true security door. These types of doors not only look great but they also allow you to take in views without obstructions.

The moral of the story is if you are looking for a security door, not a barrier door,  always look for certified products that have passed the relevant Australian Standards.

Choosing the right windows and doors for your next project

There are several factors to weigh up when choosing the right windows and doors for your project. Windows and doors are major architectural components in the design of a building and need to be carefully selected. Working with Darley Aluminium means that the research has already been done for you but let’s take a look at some of the things that need to be considered.

All Australian windows and doors must meet certain requirements under Australian Building regulations. To ensure they can withstand Australian conditions, Darley Aluminium’s products are tested for attributes including wind loads, air infiltration, water penetration and ultimate strength.

The National Construction Code (NCC) is produced and maintained by the Australian Building Codes Board (ABCB). Under the NCC, the Building Code of Australia (BCA) is a uniform set of technical provisions for the design and construction of buildings and other structures throughout Australia. It allows for variations in climate and geological or geographic conditions.

“A very important factor to consider when choosing a window is the wind load, as it’s a deciding factor for the type of window that will be used as it needs to structurally withstand the loads on the site,” said Ray Kwan, National Sales Manager. “Serviceability Limit State (SLS) and Ultimate Limit State (ULS) are the two different types of ratings that measure the wind loads for windows and doors.”

Two Australian Standards are used to determine wind loads for a building: AS/NZS 1170.2 Structural Design Actions and AS 4055 Wind Loads for Housing. Every site for every building in Australia should be assessed for wind load requirements according to AS/ NZS 1170.2 Structural Design Wind Actions or AS 4055 Wind Loads for Housing.

Once the building/site requirements have been determined the next step is to ensure the windows being selected meet these requirements. Windows need to be tested for several conditions that will impact on their performance and durability. They are tested in accordance with the requirements in AS 2047.

The tests completed during this process
include:

• Structural: Measures deflection of the window (SLS) at Span/250.
• Operating Force: Confirms opening force is within the set limits.
• Air Infiltration: Measures air leakage through the window or door.
• Water Penetration: Measures water penetration resistance (WPR).
• Ultimate Strength: Confirms the window meets ULS requirements.

“Windows are tested for combinations of wind loads (SLS and ULS) and WPR for all classes of building types. Based on the requirements for the type of construction and site, the performance results dictate where the windows and doors can be used,” said Ray.

To ensure performance and durability, Darley Aluminium make sure that their products meet all of the following BCA provisions:
• Products are structurally adequate to meet site requirements for SLS and ULS.
• Products have a water penetration resistance that meets the site requirements.
• Flashing required to window and door systems to prevent water penetration around the system.
• Manifestation required for glass doors and panels that could be mistaken for a door or unimpeded path of travel.
• Bushfire requirements.
• Balustrades and barriers. This includes restricted or protected openings.
• Energy efficiency requirements.
• Sealing requirements to stop air leakage which significantly reduces energy efficiency.

By choosing a tested and certified Darley Aluminium system, you have the confidence that the chosen product will meet the stringent requirements of the Building Code of Australia. “All of Darley’s window and door systems including our KlassicView residential and CityView commercial systems have been tested according to all these stringent testing requirements of the Building code of Australia,” said Ray.

Darley Aluminium is an Australian, family owned and operated business with warehouses in New South Wales, Queensland, Victoria and Western Australia. With over 25 years of experience, Darley Aluminium has developed into a highly respected business in the aluminium industry.

Why good quality stainless steel mesh is so important for your security door or window?

Stainless steel mesh is an important component of security windows and doors

As a home owner, installing a security window or door is pretty straightforward

– you contact a security fabricator, they install the security door or window and your home is secure!

We all know stainless steel mesh is an important component of security windows and doors. But did you know slight differences in the techniques and procedures used by suppliers to manufacture this mesh, can equate to significant differences when it comes to the performance of the mesh?

Let’s explore some of the factors that affect the quality and performance of stainless steel mesh used in security windows and doors. Stainless steel mesh is an important component of security windows and doors. There are hundreds of suppliers of stainless steel mesh around the world, claiming to have the highest quality mesh at the most affordable prices. It would be quite a challenge for any security fabricator to compare the various suppliers and the quality of the mesh they manufacture.
There are a number of important attributes to consider when analysing the quality and performance of stainless steel mesh including:
* Raw materials and wire composition
* Weaving techniques and equipment
* Powdercoat finish
* Testing and compliance
* Regular cleaning and maintenance

good quality stainless steel

What’s the difference between 304 and 316 marine grade mesh?

I am sure you have heard many security brands use the term 304 marine grade stainless steel or 316 marine grade
stainless – sounds high tech but what does it actually mean?

Marine grade refers to stainless steel, that is suitable for marine environments and exposure to elements such as water, strong winds and saltwater corrosion.
304 marine grade stainless steel is generally used in outdoor environments, food processing and manufacturing
facilities – it has a chemical composition of 18% chromium and 8% nickel and provides reasonable corrosion resistance.

While 316 marine grade stainless steel also has a composition of 18% chromium and 8% nickel but with the addition of 2% – 3% of molybdenum, a metallic element that works in conjunction with the nickel alloy to provide a higher level of corrosion resistance.

Darley’s ScreenGuard stainless steel security mesh system is made with 316 marines grade stainless steel mesh, making it the perfect security system for residential homes, particularly coastal environments. Overall 316 marine grade stainless steel is considered superior over 304 marine grade stainless steel because of its higher level of corrosion resistance.

Wire Composition

As you probably already know stainless steel mesh is made of intersecting columns of stainless steel wire. This type of mesh has been around for centuries and is used in a number of applications such as fencing, barricading, grills, sisters and metal safety gloves.
As mentioned previously, the type of marine grade stainless steel is an important factor to consider because of its chemical composition and marine grade 316 is considered the superior mesh because of its higher corrosion resistance.

With the increasing popularity of 316 marine grade mesh, it has never been more important to reassure customers of the quality of the mesh used in their security products. It is for this reason, Darley send samples of our screenguardmesh to third party laboratories to verify the chemical composition of our stainlesssteel mesh and ensure customers receive quality 316 grade stainless steel.

Another aspect that needs to be taken into consideration is the diameter of the wire used in the stainless steel mesh. In Australia, the two most common wire diameter sizes are 0.8mm and 0.9mm. Our ScreenGuard system uses wire with a diameter of 0.8mm. The same wire diameter has been used in the manufacturing of ScreenGuard mesh for over 15 years, offering consistent quality and appearance but also making it slightly challenging in the weaving process with the thicker wire being harder to weave.

Another aspect that needs to be taken into consideration is the diameter of the wire used in the stainless steel mesh. In
Australia, the two most common wire diameter sizes are 0.8mm for 316 marine grade mesh and 0.9mm for 304 marine grade mesh.

Our ScreenGuard system uses wire with a diameter of 0.8mm. The same wire diameter has been used in the manufacturing of ScreenGuard mesh for over 15 years, offering consistent quality and appearance but also making it slightly challenging in the weaving process with thicker wire being harder to weave. The tensile strength of the individual steel wire is an important contributor to the strength of the stainless steel mesh.

Tensile strength is the measurement of force the wire can withstand before it breaks. The stainless steel mesh used in the ScreenGuard system has a tensile strength of 850 – 900 pascals. Meaning it can bear a heavy load before breaking
– making it an ideal barrier in extreme weather conditions. It’s interesting to note – it is possible to increase the tensile strength of a single strand of stainlesssteel wire. This process is referred to as quenching and involves applying a heat treatment to the wire, followed by rapid cooling – which alters its chemical properties and increases or decreases its tensile strength.

Weaving Process

Having a high quality wire is one of the most important parts of the process but this doesn’t mean anything if it’s not combined with an effective weaving process.
There are generally 2 ways of combing metal wire to create a sheet of mesh:
– a welded wire mesh process
– a woven wire mesh process

The welded wire process for creating mesh is made using an automatic type welding machine that welds intersecting wires together to create a permanent
bond. While the woven wire mesh process uses a specialised machine and a spinning technique that shoots out the wire in a fast-action motion to create the mesh.

Our ScreenGuard stainless steel mesh uses the woven method, which relies on the precision of specialist machines.
These machines are precision-engineered, German and Japanese made machines that shoots out the wire in a fast moving action to create the weave pattern and also sets the size and shape of the hole aperture.

Consistency and appearance of the mesh

Quality is one thing, but we also want our
mesh to have a flat, smooth and consistent appearance. Not only is this aesthetically pleasing to the home owner but it also assists in providing protection from debris, pests and corrosion. The precision of the specialist weaving machines play a vital role in keeping the mesh smooth, flat and free of imperfections.

Powdercoating

We all know powdercoating is a type of finishing that is applied to a surface using a free-flowing dry powder. It is applied using an electrostatic process and then cured under heat. Our ScreenGuard mesh is supplied powder coated black and is covered by our 10 year warranty.
To ensure a consistent and smooth  powdercoat finish, the mesh should undergo a pre-treatment to clean and decontaminate the surface. Not all mesh suppliers apply a pre-treatment prior to powdercoating, which affects the longevity of the finish. ScreenGuard’s mesh suppliers always pre-treat the mesh, which rids it of contaminants such as oil, grease, surface corrosion and free floating particles.

Test Reports

Most security fabricators are familiar with the tests applied to security products under the Australian Standard AS 5039- 2008. One of the tests used in the standard is the Knife-shear test, which is designed to imitate a knife attack from an intruder, where they attempt to cut through the mesh of the security window or door.

Our ScreenGuard security products have been tested for and meet Australian Standard AS5039-2008, passing the knife
shear test, as well as, other compulsory tests including dynamic impact, antijimmy, child fall prevention, bushfire and fire attenuation.

In fact, the supplier of our ScreenGuard mesh goes one step further and applies their own knife shear and salt spray tests.
Every time we receive a new batch of mesh from our supplier, they provide an independent knife shear test report and salt spray test report – which confirms over 1000 hours of testing with no signs of corrosion. Darley also conducts spotcheck testing with a NATA accredited laboratory to provide a secondary level of QA screening.

Another important factor that needs to be taken into consideration is the actual installation of the security doors and windows. AS5039 is the standard that governs manufacturing of security windows and doors, while AS5040 is the Australian Standard that for installing Security screen doors and window
grilles. This standard provides installers of security screen doors and grilles with specifications for installing security screen doors and window grilles used primarily= in residential applications. If the security product is not installed correctly and according to these standards, then it is not considered secure.

Regular maintenance and cleaning

We have highlighted many factors, that influence the quality and performance of mesh – most of which are related to the manufacturing process. One very
important contributing factor, influenced by the homeowner is regular cleaning and maintenance of security doors and screens.
It’s all good to discuss advanced manufacturing techniques but it means nothing if the homeowner doesn’t regularly clean their security screens to protect against corrosion. The frequency of cleaning is dictated by the type of environment the home is located in.

What is an Aluminium Extrusion? https://darleyaluminium.com.au/what-is-an-aluminium-extrusion/ Wed, 10 Mar 2021 04:42:15 +0000 https://darleyaluminium.com.au/?p=14143 It might be hard to believe but the process of aluminium extrusion has been around since the early 1900s. Incorporating aluminium extrusions into the design and construction of residential & commercial buildings, led to significant changes in the construction industry.

Aluminium is all around us, from aluminium windows and doors to the cans of soft drink we consume every day. Today we will learn more about aluminium extrusion and the process of how they are manufactured.

What is aluminium extrusion?
Aluminium extrusion is the process used to extrude aluminium alloy into objects or shapes that can be used in a variety of applications.

The extrusion process exploits aluminium’s unique combination of physical characteristics.
The metal’s malleability makes it easy to machine and cast, while its weight is one third the weight of steel but provides the same amount of strength and stability.

What is an aluminium Extrusion – The process in 8 steps

It might be hard to believe but the process of aluminium extrusion has been around since the early 1900s. Incorporating aluminium extrusions into the design and construction of residential & commercial buildings, led to significant changes in the construction industry.

Aluminium is all around us, from aluminium windows and doors to the cans of soft drink we consume every day. Today we will learn more about aluminium extrusion and the process of how they are manufactured.

What is aluminium extrusion?
Aluminium extrusion is the process used to extrude aluminium alloy into objects or shapes that can be used in a variety of applications.

The extrusion process exploits aluminium’s unique combination of physical characteristics.
The metal’s malleability makes it easy to machine and cast, while its weight is one third the weight of steel but provides the same amount of strength and stability.

How does aluminium extrusion work?
The process consists of aluminium alloy being forced through a die with a special cross section profile. Once it has been pushed through the die, it comes out in the shape of the die opening – to extrude different types of aluminium extrusion, you only need to change the die opening.

Some people compare the process of aluminium extrusion to the force applied when squeezing a tube of toothpaste, with the opening of the toothpaste serving as the extrusion die.

Common Extrusion Shapes
Many different kinds of shapes can be manufactured with the help of the extrusion process. The most common ones are angles, channels, squares and round tubes. Aluminium extrusions can also be solid, hollow and semi-hollow.

 

The Aluminium extrusion process with Darley’s Mill Sales division
Aluminium extrusions are something Darley knows allot about – our Mill Sales division designs and manufactures customised aluminium extrusions.


Raw Materials
The aluminium extrusion process starts with raw materials. Bauxite is the world’s primary source of aluminium. The ore is chemically processed to extract alumina, which is then smelted using an electrolysis process to produce extrusion ingots. The highest quality raw materials are used to ensure quality and strength of the products we extrude.

Extrusion Ingots
The second step in the process is getting started with the production of extrusion ingot.
These ingots can be used for a variety of purposes. They are usually produced in factories.

Extrusion Die
Extrusion dies are large, flat disks with one or more openings, that allow you to create the desired cross sectional profile. Typically, they are made of H-13 die steel and heat treated to withstand the pressure and heat of hot aluminium begin pressed through the die.

Extrusion process
This is the step where all the magic happens. The ingot is heated and pushed through the aluminium extrusion die with a powerful ram that applies extreme pressure. It emerges from the die opening in the shape of the cross-sectional profile.

Surface Finishing
Once the aluminium has been extruded and left to cool down, you can then apply a surface finish, such as clear anodising, powdercoating or sublimation to enhance its appearance.  Or if you want to go with something more natural, you can choose mill finish – which is the natural appearance of aluminium after its extruded.

Value Added Services
Darley’s Mill sales division offers a number of value added services, in addition to the design and manufacture of customised aluminium extrusions – these include powdercoating, anodising, as well as light fabrication in the form of cutting or punching.

Packaging and shipping
Last step in the process is packaging the customised extrusions in bundles or secure crates and distributing them to any location within Australia.

Cutting and folding sheet Aluminium for commercial projects

Different story when you’re talking about large scale commercial projects. When it comes to commercial projects, where you need to cut or fold an aluminium sheet with a thickness of 1.6mm or more, shears and hand presses aren’t going to be strong enough.

A metal guillotine is the best option for cutting aluminium sheets with a thickness of more than 1.2mm, its hydraulic mechanism gives it the right amount of force to cut through thicker and larger quantities of aluminium sheet.

One of the key advantages of using a metal guillotine is the fact that it’s fast, cost-effective and ideal for high volume production. Darley’s Victorian branch has Brake Press and Guillotine machines onsite that can fold and cut aluminium sheets up to 3.6m in length.

The Brake Press machine can fold an aluminium sheet into different types of folds including: a top hat, angles and z shape flashings.

Guillotine Machine

Type of Sheet Flat aluminium sheet cut to size
Lengths Up to 3.6m sheets
Sheet Thickness 1.2mm to 6mm

Brake Press Machine

Lengths Up to 3.6m sheets
Sheet Thickness 1.2mm to 3mm*
Types of Folds -Top Hat
-Angles
-Z Shape Flashings

The challenges in developing a bottom rolling multi-fold door system

Open plan living has gained popularity over the last few years. Its not hard to understand why, a multi-fold door system increases living space, light and encourages integrated living.

A practical alternative to traditional sliding doors, multi-fold doors can be used in residential and commercial applications.

Popular in residential applications in the form of expanding outdoor entertainment areas, multi-fold doors systems can also transform and upgrade commercial business including restaurants, cafes & bars.

Darley’s HarbourView multi-fold door system already came in a top-rolling version and our product designers and engineers, were eager to add a bottom rolling option to the suite to prevent the need for a load bearing lintel.

In developing this bottom rolling multi-fold system, our product designers had to bridge the knowledge gap between designing a new more standardised aluminium bi-fold, that addressed all the pain points associated with commercial bi-folds including ease-of-installation, maintenance, weight and ease of motion.

How multi-fold doors work

Multi-fold doors are made up of multiple panels on a sliding track, that can be pushed to one side with the panels folding against each other.

The majority of multi-folds are top-hung, meaning that the panels are suspended from the top guide of the frame using rollers, with most of weight concentrated in the head.
With all the weight in the head, this means the system needs adequate support in the form of a lintel. It needs to be strong enough to support the weight above the lintel, as well as the additional weight of the panels

Due to the high level of customisation, complexities in installation and high installation costs, top hung multi-folds have not been a popular choice amongst many fabricators.

Multi-fold doors are also available in a bottom rolling version. With a bottom rolling multi-fold system, there is no need for the upper beam to support the entire weight, as the bottom track carries the majority of the weight.

The challenge

The challenge for Darley’s product designers was to develop an intricate bottom rolling multi-fold door system, that provides the optimal balance between water ratings, fixing screw access, extrudability, fabrication, cost and ease of use.

Another obstacle the team faced, was designing a heavy-duty multi-fold door system, that could support the weight of the panels when they are all stacked to one side.
For example, a single panel weights 50kgs – so a six-panel door stacked to one side would result in a 300kg load bearing across the head section.

Something never tried before with this type of system, the team always knew they would be faced with design challenges.

Due to the large weights having to be incorporated into the new design, this created issues with panels dragging on the track.  After a number of trials were carried out to alleviate this issue, the profiles were then re-designed and the track location was moved to under the panel to maximise performance.  This solved all operational issues and improved reliability in a shifting build.

This alteration created another issue – water drainage!
The new location under the panel, blocked access to the drainage holes, which are essential for draining water in storms and other extreme weather conditions.

Further design work and testing was carried out, which resulted in a new design that allowed the water to drain over the new track location. Final testing was carried out, which proved successful and after field trials the HarbourView Bottom rolling multi-fold was ready to go.

The bottom rolling multi-fold door system is now part of the HarbourView Multi-fold door range
and has been fabricated and installed by a number of fabricators in commercial applications such as cafes and RSLs.
