Adhesive Gasketing (Smoke & Fire Seal)
Commonly known as "Peel-and-Stick" weatherstripping, adhesive gasketing is the standard for fast, effective smoke and draft control. These silicone or PemkoPrene™ seals adhere directly to the door stop, creating a compressed barrier that is ideal for meeting S-Label requirements in hotels and office suites.
Screw-Applied Perimeter Gasketing
For industrial and institutional environments, screw-applied door gasketing provides maximum durability. These sets feature an aluminum carrier mechanically fastened to the frame with a replaceable rubber or brush insert. This design allows for field adjustments to compensate for door sagging or frame irregularities while maintaining a UL fire rating.
Intumescent Fire & Hot Smoke Seals
Intumescent strips are a life-safety requirement for wood and metal fire doors. Under extreme heat, this material expands to fill the gaps between the door and frame, preventing the spread of flames. We stock both surface-mounted and mortised intumescent from Hager, NGP, and Pemko to restore or maintain the fire integrity of your openings.
Gasketing Fasteners
A professional seal requires the right attachment. We provide commercial-grade fasteners specifically for weatherstripping installation, including self-drilling TEK screws for hollow metal frames.
