This product typically consists of a flexible material, such as rubber, foam, or silicone, backed with a peel-and-stick adhesive. Applied to door frames or the door itself, it forms a seal to block drafts, moisture, and insects. Examples include foam tape for gaps beneath doors and rubber seals for the sides and top.
Effective sealing around doors contributes significantly to energy efficiency by reducing heat loss in winter and heat gain in summer. This translates to lower energy bills and a smaller carbon footprint. Beyond energy savings, it also minimizes noise infiltration and protects against dust and pests. Historically, similar solutions, often involving felt or fabric, have existed for centuries, but modern materials and adhesive technology have greatly improved performance and ease of application.
