Brush Seal for Aluminum Sliding Window Applications

Application notes

Where the seal sits

Brush seal can be used where a sliding sash meets the frame, at meeting rails or in profile channels designed for pile backing.

Movement and contact

The pile should maintain contact through the sash movement without folding heavily or creating excessive drag.

Application evidence

Use a profile section, installation-zone photo or old strip to show where the seal sits before discussing the product specification.
