I'm building bonus room in the attic above a garage in central Texas. Does anyone know what r values I should be shooting for on the floor, walls, and ceiling? The roof has a ridge vent, no radiant barrier on the roof decking, and it will be cooled and heated with a mini split.
Here's my game plan so far, tell me if I'm screwing up-
Floor: do a layer of closed cell foam on the top of the sheetrock from above, then fill the rest of the space with blown in rockwool.
Walls: radiant barrier osb with batts. There's going to be a small section of cathedral ceiling on one side, I was going to install baffles and batts for that.
Ceiling: blown in rockwool on top of the sheetrock.
Any advice is appreciated! |
