The plywood was fastened through the rigid foam to the rafters with long screws. Rigid insulation layers exterior to existing roof sheathing must provide sufficient thermal insulation (R-value) to control condensation risk (see climate specific guidance). Install over a water-resistant barrier. "Some rigid insulation products such as extruded polystyrene are also relatively vapour impermeable. For materials with some resistance to moisture (e.g., glass-mat faced exterior-grade gypsum sheathing is quite resistant to moisture), and/or with some capacity to safely store moisture (e.g., plywood and OSB sheathing), a much less stringent design criteria is justified than for materials with no storage (e.g., foil-faced insulation) or high moisture sensitivity (paper-faced gypsum). When it comes to insulation performance, the difference is in the details. See More + FOAMULAR Extruded Polystyrene Rigid Insulation is made in Canada and offers a combination of characteristics that result in long-term thermal performance of R-5 per inch, compressive strengths of 20 100 PSI and exceptional moisture resistance. rigid insulation, plywood or OSB sheathing, and self-adhered membrane, the CLT roof panels should be covered with a water-resistive material such as roofing felt.
