Commercial Perimeter Gasketing, Weatherstripping & Door Seals
Maintain code compliance and building efficiency with Grade 1 commercial perimeter gasketing and weatherstripping from NGP, Pemko, and Hager. Choose the install method that matches the opening: adhesive (peel-and-stick), screw-applied, kerf-in weather seals, or intumescent fire and hot-smoke strips. Listed products are selected to support UL 10C positive pressure, NFPA 80, and S-Label smoke requirements — a barrier against fire, smoke, sound, and air infiltration.
Use adhesive-backed silicone for fast corridor and hotel retrofits, screw-applied gasketing when a school or industrial frame needs a field-adjustable, replaceable insert, and kerf-in weather seals on wood or aluminum doors that already have a kerfed stop or door-edge groove — press-in, no screws, no adhesive. Intumescent seals expand under heat to close the remaining gap on fire-rated wood and hollow-metal openings. Silicone, neoprene, encased foam, vinyl, and intumescent materials cover smoke, draft, weather, and life-safety inspections.
Perimeter Gasketing Comparison Chart
| Feature | Adhesive | Screw-Applied | Kerf-In | Intumescent |
|---|---|---|---|---|
Best for | Quick retrofit / hotels | Schools / industrial / sagging doors | Kerfed wood and aluminum openings | Fire-rated gaps |
Durability | Moderate | High (Grade 1, replaceable insert) | High (replace in the kerf) | High (specialized) |
Primary job | Smoke / draft (S-Label) | Fire / sound (STC) | Smoke, draft, weather | Hot smoke / fire |
Attachment | Peel-and-stick on the stop | Screws to the frame | Press into the kerf | Surface-mounted or mortised |
Adjustment | Fixed | Field-adjustable | Fixed (set by the kerf) | Fixed |
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.
Kerf-in Weather Seals
Kerf-in weather seals press into the factory or field-cut groove in a kerfed door stop or door edge — no screws and no adhesive. Encased foam, silicone, and vinyl inserts seat flush in the kerf and replace in place when worn. Use them on wood and aluminum openings that already have a kerf, where you need a clean smoke, draft, and weather seal without a surface-mounted carrier.
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.
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.
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.
