To provide compliant Passive Fire Stopping for all wall and floor service penetrations is a prerequisite for all new build and retrofit construction applications. At PAL we make it very simple to understand what needs to be done and why. We supply full technical back-up to our contractors and specifiers. Providing Engineered solutions is also a service we offer.
Nullifire FB750 is a lightweight 4-hour fire barrier comprising of a mineral fibre board with an elastomeric, ablative water-based sealant. To reinstate service penetration openings within compartment walls and floors, stopping the potential path for fire and providing a thermal, fire, smoke and acoustic seal.
When used in conjunction with FS702, the FB750 board is suitable for sealing around the following service types: non-combustible pipes, cable trays, ladders and baskets (perforated or non-perforated), armoured cables, data cables, HV cable, cable bundles up to 100 mm, dampers and ductwork.
Typical areas of use include: health and leisure facilities, schools, universities, commercial buildings, retail and industrial units.
FS702 cures to give a firm but flexible fire seal. Suitable for use in various construction movement joints up to 30%, whilst providing an excellent acoustic and air seal. FS702 is ideally suited for use around small annular service penetration seals in walls and floors. It can also be used for the bonding and pointing of joints and service penetrations in conjunction with Nullifire FB750 coated boards.
Nullifire FR230 is used to stop the spread of fire and smoke around services that pass-through compartment walls and floors, whilst providing an unsupported load bearing capacity (see Specification Information). The system also provides thermal, acoustic and air sealing performance.
