SOPRA-ISO PLUS is a polyisocyanurate insulation board with a closed-cell structure and a polymer-covered fibreglass 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.
