SOPRA-ISO is a polyisocyanurate insulation board with a closed-cell structure and a fibreglass-reinforced organic coating. Since their R-value is the highest among all types of insulation (R-5.7), the result is a thinner yet more efficient roof system. The high dimensional stability of polyisocyanurate prevents the creation of thermal bridges in the roof system.









  • Highest thermal resistance among all types of roof insulation
  • Excellent dimensional stability
  • Available with straight or shiplap edges for an installation that is twice as fast
