Weatherstrips
Weatherstrips seal the gaps around doors to prevent drafts, moisture, dust, noise, and insects from entering a building. They're essential for energy efficiency, comfort, and building code compliance.
Browse our selection of:
- Door Sweeps — seal the gap at the bottom of the door against floors and thresholds
- Perimeter Seals — seal the top and sides of the door frame
- Automatic Door Bottoms — drop down to seal when the door closes, retract when open
- Smoke & Acoustic Seals — provide fire-rated and sound-dampening protection
We carry weatherstripping solutions from Pemko and other leading brands — suitable for wood, metal, and aluminum doors in commercial and residential applications.
