A thin, flexible strip of bronze, often coiled or tensioned, creates a seal against doors and windows to prevent drafts, moisture, and insects from entering. This metal barrier typically fits within a channel or track, allowing for compression and expansion with the movement of the door or window. An example includes its application to the bottom of a frequently used exterior door.
Effective sealing contributes significantly to energy efficiency by reducing heat transfer, thus lowering heating and cooling costs. Historically, bronze has been a favored material due to its durability, corrosion resistance, and ability to maintain its spring-like properties over time. This makes it a robust solution in demanding environments, especially where exposure to the elements is a concern. The material’s resilience ensures long-lasting performance, reducing the need for frequent replacement and maintenance.
