Step 1 : Apply double-faced tape
Door/window insulation kits contain plastic sheeting and double-faced tape. Measure the double-faced tape to fit around the window frame and cut strips to fit around the outer edge of the window frame and on the bottom of the protruding sill or on the face of the frame. Apply the strips by pressing firmly to make sure the tape adheres securely. You can install the tape on metal, painted wood or vinyl. Don't apply to wallpaper, wallboard, plaster or veneer paneling.
Step 2 : Press on the plastic sheeting
After applying the tape wait 15 minutes before installing the sheeting. Peel the backing paper from the tape across the top of the frame to expose the second adhesive side. To avoid wrinkles, hold the plastic sheet at upper corners and apply it to the tape with firm, constant pressure. Smooth out the surface. Remove the backing from the tape across the bottom of the frame and attach the plastic sheet. Leave enough slack in the plastic sheet film so the shrinking process will not create excessive tension. Then repeat the process for the sides.
Step 3 : Apply heat
Turn on a hand-held hair dryer to its highest setting. Starting at a corner, move the dryer slowly across the plastic sheeting to shrink it until all the wrinkles have disappeared. Hold the dryer about one inch from the surface, being careful not to touch the plastic with the hot dryer. When all wrinkles have been removed, trim off the excess plastic with scissors or a utility or craft knife.
