Interior air sealing and tongue & groove in weekend cabin
Zone 3, central/south Georgia hot/humid climate 300 sq. ft. weekend cabin with wall unit a/c, on piers (2×10 joists w/R30) with 2×6 stud walls; R19 fiberglass batts; good attention to caulking all seams/cracks and can spray foam around windows, door, penetrations; 1/2″ plywood sheathing, 1/2″ Rmax; weathermate plus housewrap, then finally cement board siding. Toilet, shower and sink with vent through the exterior wall. This will be a weekend getaway place – not lived in for more than a few days at a time. No washing machine.
Question: Would we be potentially creating a problem by installing a layer of weathermate plus wrap behind the T&G pine planks? Trying to save a few labor dollars and not going with the full airtight drywall approach then attaching the T&G to the drywall. Would there be another option for behind the T&G? Or, under our circumstances of this being a weekend place, just attach the T&G to the studs and understand it won’t really matter.
Thanks in advance, Mr. Martin. You replied several months ago before the project got underway; I’m now ready to finish the interior and need your – and all other – comments.
