The area inside a SIP building envelope is considered conditioned space and will be ventilated by the buildings HVAC system. There is no need to provide a vented attic beneath a SIP roof, and doing so would compromise the conditioned space of the building. Some advocate venting the roof by providing an air space between the C-SIP roof panels and the roofing material (known as a cold roof). This practice is not a requirement forC- SIP buildings, but an extra measure to improve the durability and moisture resistance of the building.
