Within the absence of an airtight ceiling, roof ventilation can do extra damage than superior, since air movement in rafter bays can stimulate indoor air to leak by ceiling cracks.

Set up rigid foam insulation above the roof sheathing and air-permeable insulation concerning the rafters. Such a assembly is created to dry to the inside, so the assembly must under no circumstances contain an interior polyethylene vapor barrier. If you end up picking this technique, it’s possible (although not essential) to set up vent channels amongst the top of the rigid foam and the best layer of roof sheathing by installing a number of parallel 2x4s — a single above Each individual rafter — extending from soffit to ridge. (To find out more on this strategy, see How to Install Rigid Foam On Top of Roof Sheathing.)

Make sure that the thickness on the spray foam is suitable to meet least code needs. Do not forget that open up-cell spray foam is risky in all local climate zones, and if open-cell spray foam is set up Within discover here this location in a cold weather, the underside in the cured foam need to be included with gypsum drywall which has been painted with vapor-retarder paint. Vapor-retarder paint is ineffective whether it is sprayed right about the cured foam.
