Thermobreak RT

lightweight thermal insulation

Thermobreak® RT is a premium, thermal insulation product manufactured from physically crosslinked, closed-cell polyolefin foam. Unlike open-cell foam or fibre-based insulation, Thermobreak® RT is designed to maintain thermal performance when exposed to moisture.

Thermobreak® RT can replace conventionally used EPDM and nitrile based foams to combat condensation around air conditioning ducts, walls and ceilings. Its lightweight nature makes it the ideal choice for extremely weight sensitive applications such as in the rail industry.

The flammability properties from Thermobreak® RT meet some of the most stringent fire requirements. It achieves some of the highest fire ratings set out by rail and building industries such as EN 45545-2, BS 476 parts 6 & 7 and BSS 7239.

Thermobreak® RT’s exceptional durability and lightweight properties offer comfortable handling for all applications. It is also available with a facing to enhance product performance and protect it from water, oil and other liquid ingresses.
