Vaulted open-beam ceiling in Hawaii — concern for trapping moisture?
We have an old Hawaii home that is open air –windows open 24/7. The inside and outside are warm with a pretty high humidity.
The main room is a high open beam vaulted ceiling with a plywood ceiling. The plywood is also the roof deck. For looks we want to install cedar planks between the open beams.
The Plan (Sketch attached) : install 1×2 (or similar) furring strips inside the beams against the ceiling. Attach the cedar planks to the furring strips.
This will leave a 1 ½” gap between the cedar planking and the ceiling.
Optional – we may install radiant barrier on top of the cedar planks with the shiny side up toward the air gap.
Question – is there any concern for trapping moisture in this space?
Thank you for your time and comments,
