The video explains how to reduce heating costs by sealing gaps and cracks around doors and windows, and then shows how to apply a thin food film to the window frame. It details the steps: attach tape to the frame, roll the film from the top, secure it at the bottom, and trim it so it doesn’t bunch up. The film creates an insulating air gap between the glass and the frame, keeps condensation out, and lets light through, helping to keep the house warm and save money.
