Seal up a drafty window and keep your energy bills under control with an inexpensive window insulation kit. It isn’t pretty or a permanent solution, but an interior storm window is a quick-fix to stop wind from whistling through old rattling windows.
Window insulation kits, sold in hardware stores and home centers, contain plastic sheeting and double-faced tape that you cut and install on the inside of the window. You measure the window and cut the sheeting, tape the sheeting to the window trim to cover the glass, and then install it using a hair dryer. The blast of hot air from the dryer creates a shrink-wrap that seals the window from inside and creates a clear, tight-fitting film. You also need a measuring tape, scissors, a utility knife and a stepladder.
