Abstract
A profiled rubber strip seal for bordering window and door openings. To simplify installation, or to promote relative movement between the strip and windowpanes, such seals are provided with overlay strips of friction-reducing material, especially synthetic materials that contain fluorine. To provide favorable conditions for satisfactory bonding between the overlay strips and the main strip, and also to make it possible to use difficult to handle materials, the elastomeric mixture of the main strip is altered by including therein silicic acid.
