How to Winterize Windows With Plastic
- 1). Cut a piece of plastic film slightly larger than the window you want to cover. The two best types of plastic to use are shrinkable plastic film and heavy-duty plastic sheeting like a drop cloth.
- 2). Apply double-sided tape to the frame of the window. If you notice a draft coming from behind the window casing, apply the tape to the drywall just beyond the casing.
- 3). Put the plastic wrap onto the double-sided tape. Take your time to avoid creases and runs in the plastic, which should be applied evenly and tautly.
- 4). Shrink the plastic film using a hairdryer set on low. Constantly move the hairdryer back and forth to prevent the hairdryer from melting the plastic. Stop when there are no wrinkles on the plastic wrap.
- 5). Cut the excess plastic film from the side of the double-side tape opposite the window.
- 6). Inspect the plastic for leaks. The double-sided tape can pull away from the window frame as the hairdryer tightens the plastic. Add double-sided tape to where you find leaks.
