140mm PIR insulation is ideal for general insulation and applications that require a thick insulation board to boost thermal performance.

What is 140mm PIR insulation?

The 140mm PIR insulation board has a thickness of 140mm. It consists of a PIR centre flanked by a foil or glass tissue backing on each side. The board has exceptional thermal insulation properties, high moisture resistance, and a lightweight build.

What are 140mm PIR used for?

Due to its thick form, 140mm insulation may be ideal for some specialised applications — check with the manufacturer. It is also commonly used for these applications:

• Flooring — Use with concrete slabs, suspended timber floors, and beam and block flooring systems.
