What are Fire Sleeves?

Kooltherm FireSleeve Fire safety is a major concern for many in the building services industry, and with virtually all mechanical and electrical applications needing to penetrate through fire-rated building elements at some point, it is not enough to simply specify service products and surrounding insulation which achieve a high level of fire performance.

There are a number of fire stop options on the market, but for pipework applications the simplest solution is often to fit a fire sleeve , with vapour barriers maintained as the insulated pipework passes through the building element. Fire sleeve products typically comprise an intumescent layer inside a metal facing which is sealed at both ends with compressible rings. In the event of a fire, the high levels of heat cause the intumescent layer to swell to several times its original size and form a hard char, closing any gaps between the pipework and penetration edge.
