- Fire and smoke seal featuring high expansion pressure
- BS 5588: Parts 1 and 2.
- A fire and smoke seal from Sealmaster.
ULTIMA is a seal which combines gap-filing 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, Ultimas triple action provides fire and smoke protection for 30 and 60-minute door assemblies. 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 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 a draught seal in normal use and resists the passage of smoke, thus meeting the needs of BS 5588: Parts 1 and 2.
Ultima fire and smoke seals are normally rebated into the head and jambs of the door edge. 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. 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 examples describe independent fire tests for both the 30 and 60 minute fire door assemblies.
We have technical representatives who provide assistance in the selection and specification of the products on this site and should be consulted for exact installation and product suitability. Ensure an early engagement with ourselves, designers, main contractor and specialist installers before any installation. Other trades and/or manufacturers may need to be consulted. For in-depth information, specification and technical advice please call our Head Office on Tel: +(0)1329 841416 or email email@example.com
All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 Code of Practice for the Installation and Inspection of Fire Stopping.
It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
