Product Details

Weatherstrip Foam-Filled Kerf Back Polyflex Bulb - 0.250" Reach

Kerf-mount weatherstrip with flexible polyflex bulb and closed-cell foam core designed for standard window frame slots. The flexible bulb design requires minimal insertion force and conforms closely to sealing surfaces, reducing air and water infiltration without creating binding or resistance at sash movement.

Closed-cell foam structure prevents water penetration into the foam cell matrix while the extruded skin provides UV resistance. This combination extends service life in exterior applications subject to direct sunlight and moisture cycling.
