Sealing the gaps between a wooden door and its frame is essential for energy efficiency and comfort. Various materials, including foam, rubber, felt, and metal, are used to create this barrier against drafts, moisture, and noise. For example, a thin strip of adhesive-backed foam can effectively seal a small gap, while a more substantial bronze sweep might be necessary for a larger gap at the base of a door.
Effective perimeter seals significantly reduce energy loss by preventing heated or cooled air from escaping. This translates to lower energy bills and a smaller carbon footprint. Furthermore, such seals help maintain a consistent indoor temperature, enhance sound insulation, and prevent the ingress of dust, insects, and water. Historically, materials like felt and animal hair were employed; however, advancements in material science have led to more durable and effective options.
