Welp, back working on the addition full force on weekends. Office has all the T&G;pine walls & ceiling up, electric, tv, phone, networking & satellite internet wiring run. Bedroom has 1 small and 1 large wall left. The end walls are for the end of project. Everything concrete will be covered in dry stack ledge stone cultured stone. (Gonna be a wopper in cost). Heres a few shots of the newly insulated and covered in pine 8" T&G;. I went overkill for tightness. All the 2"x6" outside wall studs & top & bottom plated caulked with silicone where the inside of outside sheathing meets the studs. No gap sparred. Even around doors where studs are doubled & trippled in some spots, the places where the studs meet side by side are caulked. There are NO air gaps. Even caulked the outside lamp boxes where the go through wall. Now working on enclosing & prettying up the old exterior chimney which is not interior in the new bedroom. That will also get covered in cultured stone. Except the sides. While it is not unbearably hot to touch when Summit is cooking along. It does get warm, and I figure I'll take the free heat towards the bedroom. Hopefully the cultured stone will radiate a lil, even if minimal. and decided to box the sides at the step in's and put a cloverleaf pattern aluminum perforated sheet metal on the faces to let any other even if small bit of heat radiate out into bedroom.
