Rubber weather seals, commonly referred to as weatherstripping, are designed to fill the gaps between frames and their movable parts. They work to prevent drafts, water leaks, and thermal exchange, creating an effective barrier against external weather conditions. With a variety of materials used to manufacture these seals, rubber stands out due to its flexibility, durability, and excellent sealing properties. It can handle extreme temperatures, resist degradation from UV exposure, and maintain its performance over time.
