Here we go again Reno. Oh man… I thought we were past all of this! What does a really large window and a window tint deal that is to good to be true add up too? A light gap the size of the Grand Canyon! And yes, we have ourselves another Hack Alert.
Sun damage results from heat, visible light, and UV radiation. Of course, one does not want to overly reduce the visible light transmittance on a storefront window because it would make it hard to see the merchandising behind the glass. So the trick to reducing sun damage is to use spectrally select window films that allow high visibility but at the same time reject over 50% of the heat and 99.9% of the UV rays.
