Norseal stock a range of Sealmaster intumescent seals, including the highly capable Ultima 60(S). The 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 at a lower pressure than the graphite.
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.
