** Hot Smoke Seal™ fire tested: Listed to meet the requirements of standards UL10B, UL10C, UBC 7-2,
Part 1 and BS476: 1987 for application to fire rated door assemblies. Tested for smoke controlled assemblies: Listed to meet the requirements
of standards UL1784, NFPA 105, UBC 7-2, Part 2, and BS476:Part 31, Section 31.1:1983.
It also is a chemically inert, highly stable, expandable graphite strip, tested and proven in positive pressure conditions to withstand
both hot smoke and hot gasses, resulting in the longer integrity of a door assembly. More economical to use than specially modified
doors in “tested assembly only” classifications. Chemically inert, and therefore will not degrade from carbon dioxide and ozone like
the many intumescents being offered by other manufacturers.
Hot Smoke Seal™ is not affected by moisture and will not break down like fiber or cellulose based products and does not require periodic
after market field inspections.
