They are highly effective for insulation during cold weather, maintaining the warmth generated by heating systems. Choosing the wrong type can lead to minimal benefits or even increased glare and fading.
How Window Film Insulation Blocks Summer Heat for Better Home Energy Efficiency
Low-Emissivity (Low-E) Films: These feature a microscopic metallic layer that reflects interior heat back into the room. The primary categories focus on blocking solar heat, retaining interior heat, or providing a sealed insulating barrier.
One major advantage is the protection against ultraviolet (UV) radiation. Metric What It Measures Ideal For U-Factor Rate of non-solar heat loss.
Effective Summer Heat Block with Window Film Insulation
By rejecting solar heat before it enters the glass, they reduce the load on air conditioning systems. A low U-factor signifies better insulating value, while a low SHGC indicates the film blocks a high amount of solar heat.
