Why Kingspan Thermaroof TR22?

Kingspan Thermaroof TR22 is a high performance insulation with a fibre-free polyisocyanurate (PIR) insulation core with a high compressive strength.

Kingspan Thermaroof TR22 is used for flat roofing cover boards to overlay new and existing flat roofs waterproofed with single-ply and cold liquid applied waterproofing.

Therma insulation has a fibre-free and closed cell insulation core, which has been manufactured with zero Ozone Depletion Potential and low Global Warming Potential.
  • Fibre-free core
  • Zero ODP & low GWP
  • High compressive strength
