ASWF Sky Dual Reflective Architectural Window Film

ASWF Sky Architectural Film delivers solar heat control and glare reduction with a dual reflective design that keeps interior reflectivity lower than exterior reflectivity. Designed for year-round comfort, this architectural window film helps manage summer heat while supporting a warmer indoor environment in winter.

Solar Heat Control and Glare Reduction

Make sun-exposed spaces more comfortable with window film that balances heat rejection, glare control and visible light transmission. The Sky series offers total solar energy rejection from 55% to 83% and glare reduction from 52% to 91%, depending on the film grade.

Its dual reflective construction provides stronger reflectivity on the exterior side, with lower interior reflectivity for a less mirror-like appearance from inside.

Performance Benefits and Long-Term Value

• Reduce solar heat gain: Total solar energy rejection of up to 83% helps limit incoming solar heat and can reduce cooling demand.
• Improve visual comfort: Glare reduction of up to 91% helps make bright indoor spaces more comfortable for everyday use.
• Balance daylight and heat control: Visible light transmission from 8% to 37% provides options for different lighting preferences and project requirements.
• Reduce interior reflections: Interior visible light reflectivity is lower than exterior reflectivity across all four listed grades.
• Make informed project decisions: Grade-specific performance data, NFRC documentation and specification sheets help you compare options before selecting a film.
• Evaluate potential energy value: Match solar performance to the building’s needs when assessing potential operating-cost savings. Actual savings depend on glazing, climate, exposure and HVAC use.
