Pemko S88W Silicone Adhesive-Backed Fire-Smoke Gasketing, 1/2" Width, 1/4" Height, White Color

The Pemko S88W is a silicone adhesive-backed gasketing designed to provide fire and smoke protection along door edges and frames. Featuring a compressible silicone bulb measuring 1/2" wide and 1/4" high, this white gasketing seals gaps to limit the passage of smoke and combustion byproducts during a fire event. Its self-adhesive backing allows for quick, tool-free installation on either the door or the frame stop. Built to withstand repeated compression cycles, the S88W maintains its sealing performance over time, making it a reliable choice for commercial openings where code-compliant fire and smoke control is required.

Features

• Silicone bulb construction delivers durable, long-lasting compression and recovery.
• Pressure-sensitive adhesive backing enables fast installation without fasteners.
• 1/2" width and 1/4" height provide an effective seal against smoke infiltration.
• White color blends discreetly with light-colored doors and frames.
• Engineered for both fire and smoke gasketing applications on commercial doors.

Functional Details

The S88W works by compressing its silicone bulb against the mating surface when the door closes, forming a continuous barrier that restricts the movement of smoke and heated gases through perimeter gaps. The adhesive backing holds the gasket securely in place along the frame stop or door edge.
