Kingspan Thermawall TW50 – 1200mm x 450mm All Thicknesses (Sold in Packs)


Boasting an impressive thermal conductivity of 0.022 W/mK, Kingspan Thermawall TW50 is a top-performing insulation. It has a rigid thermoset polyisocyanurate (PIR) core that is free of fibres as well as low emissivity foil facings that elevate the cavity’s thermal resistance.

Specifically designed to be used as insulation for cavity walls, this board remains unaffected by air infiltration. Furthermore, it is easy to handle and install, and the material used is non-deleterious. The blowing agent used in its manufacture also has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

  • 1200mm length x 450mm width
  • Conforms to NHCB technical requirements when used with a 50mm residual cavity
  • Low emissivity composite foil facings
  • Clear cavity is maintained and moisture penetration is resisted
  • Thermal Conductivity of (as low as) 0.022 W/mK
  • Handling and installation are easy
  • Unaffected by air infiltration
  • Fibre-free and high-performance core
