Description

Rigid PIR insulation board 1200 x 2400 x 150mm is a lightweight, high-performance thermal insulation solution for new build, refurbishment and retrofit applications. The board format allows straightforward handling and installation across floor, wall and roof applications in trade and serious DIY workflows. We stock Ecotherm, IKO, Mannok, Recticel and Unilin brands depending on current availability; you will receive whichever brand is in stock at the time of order.

The product delivers thermal conductivity of 0.022 W/mK with compressive strength of 175 kPa, meeting specification requirements for structural and thermal performance. At 150mm thickness, this board is commonly specified for floor insulation, roof insulation and cavity wall applications where thermal performance and load-bearing capacity are required. BBA-backed product assurance provides confidence in performance and compliance for specification-led projects.
