FEATURES & BENEFITS
ULTIMA 60(S) Intumescent Fire and Smoke Seal is a seal which combines gap-filling properties with a high expansion pressure seal, to improve the stability of a door assembly during a fire. Using two distinctly different types of intumescent material and an elastomeric smoke blade, Ultima’s triple action provides fire and smoke protection for 60 minute door assemblies.
The intumescent fire and smoke seal consists of an easily fitted aluminium holder, with two reservoirs and a self-extinguishing, elastomeric smoke blade. The first reservoir contains an expandable graphite compound, which combines high pressure with a multi-directional foam, designed to restrict door movement. The second reservoir contains a mono-ammonium phosphate-based formula, which produces continual foaming, up to 40 times its original volume. This is especially valuable when sealing large and moving gaps. The elastomeric smoke blade acts as an efficient draught seal in normal use and resists the passage of smoke, thus meeting the needs of BS 5588: Parts 1 and 2.
Ultima intumescent compounds are inherently resistant to atmospheric carbon dioxide and moisture, so that additional protective coatings are unnecessary. These claims are substantiated by laboratory controlled tests and, in the case of the mono-ammonium phosphate formula, by actual case histories.
AUTHORITY
The Ultima Intumescent Fire and Smoke Seal has been tested by TRADA. The criteria covering evidence of performance across variable fire-resisting doorsets are wide ranging. The following example describes the independent fire test for a 60 minute door assembly.
