Thermawall TW50

Thermawall TW50 is a high performance cavity wall insulation board with a thermal conductivity of 0.022 W/mK. Available in a range of thicknesses.

Product Highlights

High performance rigid thermoset polyisocyanurate (PIR) insulation - thermal conductivity 0.022 W/mK
Low emissivity foil facings significantly increase the thermal resistance of the cavity
Clear cavity is maintained - resists moisture penetration
Easy to cut, handle and install compared to some other commonly used insulants
