Thanks to all who have responded to earlier posts about a screened porch. One last question, hopefully. I plan to use philippine mahogany (I know, not real mahogany.) I want to butt the boards together to prevent bugs from coming up from under the porch. Any problems with expansion I should be aware of? Read someplace that boards should be spaced the thickness of a putty knife. Will sealing all sides prevent any significant expansion? Thanks again.

Bugs under porch
Place screen on top of the joists before the deck boards and the gap will be sealed.
