As the winter settles in, you are bound to notice more drafts coming from windows. Without proper insulation, windows represent one of the biggest heat wasters in your home. In fact, leaving your windows bare for the winter is about as useful as leaving one window open in each room halfway.
Caulking windows and buying expensive pre-made insulator covers can be costly. Rather than go that route, you can try this caulk-free vinyl window solution that I have been using for decades. It can easily be adapted to accommodate different climates without much in the way of additional cost.
As an added bonus, this system can easily be assembled from scavenged materials before and after a crisis.
