Pemko HSS2000-7 – Frequently Asked Questions

1) What does the Pemko HSS2000 hot smoke seal actually do in a fire?
The HSS2000 is an intumescent edge seal built on expandable graphite. Under heat the graphite profile swells to roughly 30 times its original size, filling the gap between door and frame so hot smoke and hot gases cannot pass through the opening. It does nothing at ambient temperature, which is the point - it stays out of the way until the heat triggers it.
2) Is the Pemko HSS2000 the right seal for a Category B fire door?
Yes. The HSS2000 is a Category G edge-sealing system, which is what a Category B fire-rated door assembly calls for. If your door schedule or listing calls out a different category of seal, this is not the substitute.
3) Is the Pemko HSS2000 a weatherstrip or a perimeter smoke gasket for daily smoke control?
Neither. The HSS2000 is an intumescent seal - it works only when heat activates the graphite. It is not a compression gasket for cold smoke, air infiltration, or sound, and it will not seal a drafty exterior opening. If you need an ambient-temperature seal, use a perimeter gasket; on a fire door you often need both, the intumescent for the fire condition and a gasket for cold smoke.
4) Does the Pemko HSS2000 smoke seal need screws or fasteners to install?
No fasteners. The HSS2000 is self-adhesive and presses onto the side of the frame, so it goes on with no drilling and no special tools. Frame surface should be clean and dry for the adhesive to hold.
5) Will the Pemko HSS2000 graphite seal break down over time in a humid or high-traffic building?
The graphite is chemically inert and the base is a flexible elastomer, so it is not affected by carbon dioxide, ozone, or moisture. That is the practical difference from fiber or cellulose-based intumescents, which degrade in service. For healthcare, education, and multi-tenant residential fire doors that sit for years before they are ever tested, that stability is what matters.
6) Can I paint the Pemko HSS2000 smoke seal to match the frame?
Yes, it's paintable. The material is gray as supplied and takes paint so it can be finished to match the door or frame color, which is usually what a property manager wants on a corridor of fire doors that are already painted out.
