To put plastic on windows, start by cleaning the window surface. Next, measure and cut the plastic sheet to size, leaving extra around the edges. Apply double-sided tape around the window frame, then carefully press the plastic sheet into place. Use a hairdryer to shrink the plastic, creating a tight seal that helps insulate the window and reduce drafts.

Installing plastic on windows is a simple and cost-effective way to insulate your home during the winter. This method reduces drafts, improves energy efficiency, and lowers heating costs. A hairdryer helps create a snug fit by shrinking the plastic, sealing out cold air and preventing heat loss.
