Product Details
Weatherstrip Kerf Back Polyflex - 0.320" Reach
Kerf-mount weatherstrip with extended reach designed for deeper or more demanding sealing applications. Seamless compression seal with nearly 100% closed-cell foam structure prevents water penetration through the foam. The extruded skin provides a durable UV-resistant barrier, critical for south- and west-facing frames exposed to continuous sunlight.
Flexible polyflex bulb offers superior conformance to irregular surfaces while maintaining low insertion resistance. Suitable for retrofit installation in existing window frames or new construction applications requiring reliable long-term performance.
