Seals designed for sliding door frames prevent air and water infiltration, enhancing energy efficiency and protecting interiors from the elements. These barriers typically consist of materials like foam, rubber, vinyl, or felt, fitted into grooves or attached with adhesive to create a tight seal between the door and its frame. Various profiles and sizes accommodate diverse door types and frame designs.
Effective perimeter sealing significantly reduces energy loss by minimizing drafts and heat transfer. This contributes to lower heating and cooling costs, and a smaller carbon footprint. Furthermore, such sealing prevents moisture ingress, which can lead to mold, mildew, and structural damage. Historically, simple materials like felt or fabric strips were employed. Modern materials and designs provide significantly improved durability, performance, and aesthetic integration.
