Window film is an easy way to add an extra layer of insulation directly to your windows. You can find this product at stores like Lowes or Walmart. Simply stick the film to your windows, and use a blow dryer to seal it.

Plastic window film covers can reduce drafts and make your home feel warmer during the winter. They are also a relatively inexpensive way to reduce condensation buildup and lower energy bills. Window wraps can also seal air leaks around the window, when those leaks extend over woodwork.

Measure the bottom of the lower sash and the top of the upper sash and then cut the foam tape with a utility knife to fit these areas. Peel off the backing and press into place.

Make Your Single-Pane Windows More Efficient
