And well aware my first photo of this material was subpar. The material is actually four layers, considered backing for a curtain, treatment. I’m thoroughly impressed with the stuff, and putting it to the test.

I covered three windows upstairs and felt a difference immediately. It’s also retaining the sun’s heat longer as a result of the ceiling sealing. While it isn’t bitter outside, it’s dark and I don’t need to see out all of the windows all the time.
This endeavor will give the wood heat a serious stretch. I’m thinking significant stretch, positive difference. I’m unable to measure the nuances between upgrades, so ultimately enjoying their sum.
