Environmental window film is arguably the best passive way to control heat gain and heat loss in schools.
Solar Window Film can reject as much as 80% solar energy which is equal to the highest performing glass. Low E window film can improve the winter insulating performance of clear, single glazing by 50% equivalent to base level double glazing.1 Window film also blocks 99% UV and can significantly reduce sun glare ensuring year-round comfort for students and staff alike.
Once installed Window Film starts to provide benefits immediately, within just 2 to 5 years, the energy savings on your bills will have covered the cost of installation.2
Manufacturer warranties span a generous 10 to 12 years, ensuring investment is protected for the long term.
Unlike traditional heating and air-conditioning systems, Environmental Window Film operates passively – it can't be turned off or on, and it won't wear out from repeated use like window blinds. It's the low-maintenance, high-impact solution your school needs to stay comfortable, efficient, and eco-friendly.
The headache of peak load
Peak Load poses the most significant expense for schools when it comes to heating and cooling. Just a single exceptionally cold or hot day can establish a peak load that reverberates over the next 6 to 18 months.
Window Film can alleviate the strain on your HVAC (Heating, Ventilation, and Air Conditioning) system during these extreme temperature fluctuations. By reducing the necessity for extreme HVAC usage on challenging days, Window Film becomes your ally in managing peak loads and ultimately saving substantial costs in the long run.
Solar Window Films energy efficiency star ratings
Window Energy Rating Scheme (WERS) is an independent energy-rating and certification program endorsed by the Association of Building Sustainability Assessors. The Australian Federal Government's Australian Greenhouse Office helped underwrite WERS as part of its commitment to improving energy efficiency and reducing greenhouse gas emissions from the built environment.
Within WERS lies a specialized program, WERS For Film, dedicated to assessing window film products, installers, and end users. This initiative, overseen by the Australian Window Association (AWA) and the Window Film Association of Australia and New Zealand (WFAANZ), ensures that consumers can confidently select window films that optimize energy performance, leading to reduced energy consumption and environmental impact.
How Solar Window Film works during summer
A key feature of window film lies in its capability to control the flow of solar energy penetrating glass.
When sunlight strikes glass, it undergoes three primary interactions – either passing through (transmittance), being reflected away, or absorbed. With window film, transmittance is reduced, while the levels of absorbed and reflected heat are increased.
Key benefits of window film for schools
Reducing energy consumption and environmental impact.
Help moderate peak energy usage through interior climate control.
Regulate hot/ cold spots.
Decrease demand on HVAC system – reduces (carbon and dollar) cost of HVAC maintenance and creates redundancy opportunities if the system can run more often on fewer chillers.
Reduce sun glare ensuring year-round comfort for students and staff alike.
