Description

Rigid PIR insulation board in 1200 × 2400 × 90mm format, designed for thermal insulation across new build, refurbishment and retrofit applications. PIR (polyisocyanurate) construction delivers consistent thermal performance with thermal conductivity of 0.022 W/mK, meeting specification requirements for wall, floor and roof insulation projects. The 90mm thickness provides practical balance between thermal resistance and board weight, reducing installation time and labour demands on site.

Compressive strength of 175 kPa ensures the board maintains structural integrity under typical building loads. Lightweight rigid foam construction allows straightforward handling and installation without specialist equipment. Available from leading manufacturers including Ecotherm, IKO, Mannok, Recticel and Unilin, with BBA-backed product assurance supporting specification confidence for architects, engineers and contractors working to building standards.
