Good afternoon,
I’d appreciate some input on a decision regarding ceiling material.
It comes down to metal, ply, or nickel-gap.
I’ve built a 25’x25’ shed/cabin. It’s got a 12:1 sloped flat metal roof.
Central Texas. Hot and humid. The space will eventually be air-conditioned.
I’m thinking about putting a corrugated metal ceiling on the interior but am worried about interior condensation.
The layup from the inside would be corrugated, ”smart” vapor barrier (certainteed membrane or similar), kraft paper faced R-39 fiberglass (14”), 2” space above fiberglass, radiant barrier face, 3/4 ply, ice/water shield, standing seam metal.
The soffit is ventilated all around with perforated hardie soffit and the 16” LVLs in the roof are all drilled with double 3” holes to allow air to flow.
Closed cell spray foam is not for me as I want to avoid any possibility of trapped water.
I can get used corrogated in 25 foot lengths and run them the length of the ceiling. Would be a pretty good look.
I’m hoping for some help on whether metal will have condensation issues. Would I be better off with wood?
Thanks
