Seals applied to the edges of sliding doors, typically made of materials like rubber, foam, felt, or vinyl, minimize drafts, water infiltration, and energy loss. These barriers block the passage of air and moisture between the interior and exterior environments.
Effective perimeter sealing significantly improves energy efficiency by reducing the workload on heating and cooling systems. This translates to lower utility bills and a smaller carbon footprint. Furthermore, such sealing enhances comfort by preventing cold drafts and minimizing noise transmission. Historically, simple materials like felt were used, but modern advancements offer a wider range of durable and effective options tailored to different climates and door types.
