Weatherstripping is an easy way to block cold or hot air from entering the home around doors, windows and electrical plates.
Step 4: Cover all gaps completely to stop drafts Apply the weatherstripping all the way around the top and sides of the door jamb. When the door closes, the insulating weatherstripping will fill all the gaps around the door. Adhesive weatherstripping is just as effective on windows. Simply measure, cut and apply the insulating weatherstripping to the bottom edge of the window where it meets the sill. When closed, it will stop drafts from entering along the bottom edge. Apply weatherstripping all around the jamb to seal out drafts along the top and sides of the door.
