Rockwool 128101 Insulated Fire Sleeve 27mm od x 25mm x 300mm

Rockwool Insulated Fire Sleeves

Fire stopping and thermal insulation solution for pipework

Many combustible pipe systems are often retro-fitted through walls and floors, compromising the fire performance of the compartment. By providing three benefits in one product, ROCKWOOL Insulated Fire Sleeves go above and beyond, offering pipe systems excellent fire, thermal and noise insulation.

Insulated Fire Sleeves are a combination of ROCKWOOL stone wool and graphite intumescent. Supplied with a factory applied reinforced aluminium foil facing.

When thermally insulated plastic pipes pass through fire resisting walls and floors, the insulation is normally removed at the point of penetration to enable standard pipe collars and wraps to close the resulting void when the plastic softens and melts due to the effects of a fire. However, the removal of this insulation may result in the formation of condensation on cold pipework or heat loss from hot pipes. Insulated Fire Sleeves avoid this problem by providing both fire stopping and thermal insulation in a single product.

Insulated Fire Sleeves are intended for use on copper, steel and most types of plastic pipes, trunking and conduits to provide up to 4 hours fire resistance.
