We recently moved into a new house, which has quite a few windows. We also have had a very warm June and early July. As a result our house has been pretty warm and uncomfortable lately. Especially since I prefer to use the AC as little as possible… usually meaning none!
I am a big fan of upgrades that will reduce our energy footprint, and especially ones that have a lasting effect of several years or more. I began researching window films that I could install myself, and eventually decided to give the Gila Heat Control Residential Window Film a try. It is available on Amazon, in several sized and varieties. I opted for the 36″ x 100′ foot roll in the Platinum color. The manufacture claims an impressive reduction in cooling costs of up to 50%. They also state it rejects up to 99% of UV, and 67% of glare. I also found that the vast majority of customer reviews were very pleased with it, some stating that it has held up well even after 10+ years of use.
