Pemko S44BL18 Silicone Fire Smoke Door Gasket Black

Product Description

The PEMKO S44BL18 is an adhesive-backed silicone fire and smoke gasketing strip designed for door perimeter sealing in fire-rated assemblies. Finished in black, this gasketing installs directly onto door frames and stops to create a continuous seal that limits the passage of smoke and flame at the door opening. At 216 inches (18 feet) per unit, the strip provides enough material to seal a standard door on multiple sides without splicing. It is used in commercial and residential construction wherever fire-rated door assemblies require compliant perimeter gasketing. Door hardware installers, finish carpenters, and life-safety contractors are the primary trades working with this product.

The S44BL18 is suited for fire-rated door frames in commercial buildings, multifamily residential projects, stairwells, corridor doors, and any opening requiring smoke and fire compartmentalization. The adhesive-backed design simplifies installation on wood, hollow metal, and aluminum frames without requiring mechanical fasteners in most applications. The black finish blends with dark-finished frames and door stops commonly specified in commercial interiors.

Installation Notes

Installation is performed by door hardware installers or finish carpenters as part of a fire-rated door assembly. The door frame surface must be clean, dry, and free of dust or oils before applying the adhesive-backed strip to ensure proper bond. Follow the door manufacturer's labeling requirements and local fire code (IBC, NFPA 80) for approved gasketing placement and coverage. Do not stretch or compress the gasket during application, as distortion can compromise the seal integrity at the door perimeter.
