new construction radiant barrier
Building will be a story and a half with four dormer windows. Roof will be 26 gauge Galvalume metal, not the dark grey I would prefer but a sliver for some hoped for "cool roof" effect. Half inch wafer plywood sheathing with #15 felt. Rafters are 2x8 on 16" centers. Deep coastal south with only a few feet at the very peak of the half story that is what might be described as an attic. For the most part it will be lived in space up there.
We haven't specified a radiant barrier...Not even sure how that would be incorporated in this style of roof...any suggestions or comments would be appreciated on any aspect of this roof. Thank you......ps....any tips on what I should insist on as for the metal roof? 26 gauge "Galvalume" is all the contract says.
