Clear Heat Control Sky Lantern 3M Prestige 70

We have been amazed at the heat reduction since Window Treat installed 3M Prestige 70 External Film

The film has been all but invisible, so we can still enjoy the sky just the same. In fact, we enjoy it even more, as the room is now not too hot to sit in. An excellent investment, we would recommend it (and Window Treat) to anyone with a lot of glass and a heat problem
