Kooltherm FireSleeves - Rest of World

Building Regulations around the world will require that where mechanical and engineering penetrations occur within a building, that they are effectively fire stopped. Failure to do so may undermine the compartmentalisation of the building, allowing flames and smoke to spread uninterrupted vertically and laterally through the concealed building cavities, putting both property and life at risk.

For pipework, the simplest solution is often to fit a fire sleeve with vapour barriers maintained as the insulated pipework passes through the building element. Kingspan’s Kooltherm FireSleeves are an ideal solution offering a 2 hour fire rating and all the benefits of Kooltherm FM Pipe Insulation.


Tarec Fire Sleeve TIMBERKooltherm FireSleeves are a unique combination of high performance phenolic insulation, intumescent and stainless steel.

These innovative products act as a 2 hour fire stop to BS EN 1366, on both steel and copper pipe service penetrations through timber frame and block wall applications, and incorporate the excellent fire and smoke performance of Kooltherm FM Pipe Insulation.


Kooltherm FireSleeves comprise an outer sleeve of 0.5mm thick stainless steel which is clasp fastening and 205mm in length. It is lined with intumescent material. The stainless steel sleeve, encloses a 300mm length of Kooltherm FM Pipe Insulation which is also lined with intumescent material.

Kooltherm FireSleeves benefit from all the performance attributes of Kooltherm FM Pipe Insulation for thermal performance, moisture resistance and in particular for fire and smoke performance.

Kooltherm FM Pipe Insulation products and Pipe Support systems achieve a BL-s1, d0 classification to EN 13501-1 when tested under the European Fire Classification System (Euroclass) for `reaction to fire’.
