Xtratherm (Unilin) Thin-R PIR Insulation Boards

Xtratherm (Unilin) Thin-R Polyisocyanurate (PIR) Insulation Boards are a high-performance insulation solution designed to provide optimal thermal comfort and long-lasting energy efficiency.   

Crafted with advanced foam technology, this foil faced Polyisocyanurate (PIR) insulation boasts a low thermal conductivity of 0.022W/mK and low thermal drift. This Xtratherm insulation in 50mm, 100mm, and many other sizes effectively minimises heat transfer to reduce heat loss and ensure a warmer, more comfortable environment.  

With a CFC-free and environmentally friendly core, moisture resistance and vapour control, these boards also reduce the risk of thermal bridging, reducing condensation and mould growth for a healthier environment.
