Since the coating is acti= vated vis UV radiation, I have to conclude that UV has a hard time traversi= ng through transparent materials such as is used in our canopies. I think just the canopy itself is filtering a lot of UV already. As for IR, are you trying to just keep it cooler inside? =20 Kevin ________________________________________ From: Lancair Mailing List [lml@lancaironline.net] On Behalf Of Thorn, Vali= n B.

There are several products from 3M, Llumar, and others with these prop= erties used on cars and glass windows every day. Has anyone one applied any window tinting or other films to their acrylic w= indows? How did it work out or not? Kim at Lancair is checking with their acrylic window vendor to see what UV = and IR filtering properties their acrylic windows already have.
