This weatherseal weatherization product is designed to resist air, water, sound, mold, mildew, dust and insects from entering into the home. This item can be used on virtually every door and window in a residence to improve the energy efficiency of the home by sealing the gaps and leaks around the doors and windows which allow outside air to enter, and inside conditioned air to escape.
