I spent the afternoon putting plastic window insulation film on my windows. It was supposed to be a short project, and I do get better at it every year, but it still ended up taking about an hour per window. Was it worth it? Does window insulation film work?
Window insulation film is a cheap, effective way to save money and make your house more comfortable in the winter. It can cut your heating bills by 30 percent.
