This type of seal is designed for sliding doors and windows, typically made of flexible materials like vinyl, rubber, or felt. It’s inserted into a channel in the door or window frame, creating a barrier against drafts, moisture, and insects. An example would be the flexible vinyl seal within the track of a patio door.
Effective sealing significantly improves energy efficiency by reducing air leakage, leading to lower heating and cooling costs. It also enhances comfort by minimizing drafts and preventing outside noise from entering. Furthermore, it protects against water damage and pest intrusion. While specific dates are difficult to pinpoint, these seals have evolved alongside sliding door and window technology, becoming progressively more effective and durable with advancements in materials science.
