This product typically consists of a flexible material, such as foam, rubber, or silicone, backed with a pressure-sensitive adhesive. Applied to doors, windows, and other gaps, it forms a seal against the elements. For instance, a strip of foam tape applied to the bottom of a door can prevent drafts.
Effective sealing improves energy efficiency by reducing heat transfer, leading to lower energy bills and a smaller carbon footprint. It also enhances comfort by minimizing drafts, preventing moisture intrusion, and reducing noise. Historically, materials like felt and putty were used for similar purposes, but contemporary products offer superior durability, ease of installation, and performance.
