Product Description

The 50mm PIR Insulation Board is a high-performance, multi-purpose rigid insulation solution ideal for use across floors, roofs, and walls. Designed with foil facings on both sides, this lightweight yet durable board delivers excellent thermal performance and long-term energy savings in residential, commercial, and industrial applications.
Manufactured from rigid polyisocyanurate (PIR), it offers outstanding insulating properties with a low thermal conductivity of 0.022 W/mK, helping to lower energy bills and reduce carbon emissions. The foil-facing enhances thermal resistance, making it a go-to solution for improving building efficiency.
With zero ozone depletion potential (ODP) and low global warming potential (GWP), this environmentally responsible product also holds an A rating in the BRE Green Guide, meeting the highest standards in sustainability and building performance.
