Conditioned attic with vented roof deck
I am planning on building a conditioned attic space in my new home. I was going to vent the roof deck by adding 1×4 furring strips and then a second OSB (with radiant barrier) to the furring strips. Vented soffit to ridge. Is the 0.75 inch airspace large enough to be effective for the radiant barrier? Or should I spec 2×4’s?
