This product category encompasses a range of materials designed to seal gaps around door frames, preventing drafts, moisture infiltration, and pest intrusion. Typically made from foam, rubber, felt, or silicone, these products feature a pressure-sensitive adhesive backing for easy installation without specialized tools. An example would be a foam tape applied to the frame of an exterior door to block cold air seepage.
Effective gap sealing contributes significantly to energy efficiency by reducing heating and cooling costs. It also enhances indoor comfort by minimizing drafts and stabilizing interior temperatures. Furthermore, such sealing protects against water damage and inhibits the entry of insects and other pests. While rudimentary forms of weatherproofing have existed for centuries, advancements in materials science and adhesive technology have resulted in highly effective and durable modern solutions.
