AWS is one of Australia’s leading designers and suppliers of aluminium window and door systems. Our brands of exterior joinery, including Elevate™ Commercial, Vantage and ThermalHEART™ are well regarded in the Australian Construction industry and are manufactured throughout the country by a network of independent manufacturers. As a market leader in its product segment, AWS recognises the importance of seeking to achieve ‘best practice’ status on a range of environmental management issues. The quest for excellence in practices that affect economic and environmental sustainability is a ‘journey’ rather than a destination, and the company recognises that ‘green’ initiatives will be part of its strategy over the long term.
ThermalHEART™ thermally broken aluminium extrusions are composed of two aluminium profiles and one or more polyamide insulating strips.
Bauxite, the ore of aluminium, is an abundant component of the earth’s crust. The smelting of aluminium and the extruding of aluminium profiles require large amounts of electricity, and this gives aluminium windows a high ‘embodied energy’. In addition, studies have indicated that aluminium and timber windows typically last for more than 40 years, while PVC only has an optimum life of 25 years.
Aluminium can be recycled indefinitely. Recycled aluminium accounts for one-third of global consumption. Even more encouraging, there is considerable scope for the recycled content of global production to be increased.
Aluminium windows are uniquely strong, lightweight, ductile and corrosion-resistant. Aluminium is also an excellent conductor of heat. By thermally breaking an aluminium window frame we can maintain the properties that make aluminium indispensable to the commercial building industry. Added insulation attributes also overcome issues associated with high conductivity, i.e. unwanted heat gain and loss to the building envelope.
The inclusion of a polyamide strip substantially improves the thermal performance of the window system. Used in conjunction with double glazing, ThermalHEART™ thermally broken aluminium window and door systems can significantly reduce the requirements for artificial heating or cooling in commercial buildings, thus lowering a building’s long-term energy requirements.
ThermalHEART™ thermally broken aluminium window and door systems are designed, tested and manufactured by Australia’s largest and most geographically dispersed network of independent window and door manufacturers. This reduces the environmental burden associated with importing and transporting similar systems from the USA, Asia and Europe. We believe that aluminium windows and doors, particularly those which incorporate ThermalHEART™ technology, offer an excellent sustainability solution for commercial green buildings.
