All of our aluminium window and door systems are rated by the Window Energy Rating Scheme (WERS). WERS rates the energy impact of windows in housing anywhere in Australia. With up to 40% of a home's energy for cooling or heating being lost or gained through windows, improving your aluminium windows' and doors' thermal performance and energy efficiency reduces your home's energy costs and Australia's greenhouse gas emissions. WERS enables windows and doors to be rated and labelled for their annual energy impact on a home, similar to the rating system used on whitegoods.
When windows and doors are rated under WERS they are ranked using a 10 star scale against 17 generic window types. The generic aluminium windows range from very high performance to very low performance for heating and cooling. A low star rating indicates poor performance whilst a high star rating indicates good performance. A 10 star rating indicates the perfect window system. In Australia, the highest performing windows typically fall between 6 and 7 stars for heating and 4 and 5 stars for cooling. ThermalHEART™ aluminium windows and doors fall within this range, as do many of our standard high performance aluminium window and door systems.
Our range of high performance aluminium windows and doors will improve the energy efficiency and comfort within a building. We are committed to the continual development of energy efficient window and door systems. Our entire product range of windows and doors are tested and rated to deliver the ultimate performance in weather sealing and energy efficiency in the Australian market.
To ensure energy efficient solutions to your window and door combination, attention must be given to the selection and placement of windows and doors within your home. By correctly placing the windows and doors in your home, you are able to maximise the use of passive design principles to achieve excellent thermal outcomes. Home orientation, insulation, shading, window selection and placement are important considerations in achieving the best possible efficiency and performance for your home.
Injury and death of children as a result of falls from windows are a tragic and preventable occurrence. The Australian Building Code has been updated in 2013 to establish regulations for the installation of windows with restricted openings in applications where there is a risk of injury or death from accidental falls. AWS supports this initiative and has undertaken extensive research and development to allow the supply and installation of compliant aluminium window systems that will reduce the risk of injury. When installing into applications which are deemed by the BCA to require the installation of guards or restricted openings, aluminium windows can be fitted with:
- Restricted opening chain winders
- Buffer stops
- Restricted opening latches
The Building Code of Australia requires restriction devices to be fitted and tested as outlined below.
Apply a 250N force with a 125mm bullet shaped object to the most vulnerable point perpendicular to the sash opening of the window for a period of 10 seconds then remove.
If the 125mm bullet shaped object passes completely through the opening at any point once the force is applied, the product would be deemed as a failure.
Barriers or locks are required to be fitted on operable windows in Early Childhood Centres and in habitable rooms of residential buildings (including apartments and multi-storey homes) where windows are more than two metres above the ground.
WINDOW SAFETY CHECKLIST
- Do all windows above the ground floor comply with BCA requirements for windows in elevated applications?
- In the event of an emergency, would windows fitted with guards/latches/locks be able to be opened to facilitate safe egress
- A flyscreen is not strong enough to stop a child from falling out of a window. Have you selected an appropriate and secure guard for your operable windows to prevent a fall?
- Are beds and other furniture kept away from windows so that children cannot climb up to windows?
- Are children taught to play away from windows?
- Are children always supervised when near windows?
