Thorfun Posted January 22, 2020 Author Share Posted January 22, 2020 3 minutes ago, A_L said: mineral wool batts will typically have a thermal conductivity of 0.035 W/m.K and PIR 0.022W/m.K. Thus 22mm of PIR will have the same insulating effect as 35mm of batt steico wood fibre batts, IIRC with a thermal conductivity of 0.048W/m.K will have the same insulating effect at 48mm thickness that actually now makes a lot of sense. thank you!
