| Hey guys, I’m a first time poster and I am seeking some important information for finishing my basement. There are no problems with flooding and water. It is cold down there in the winter and I want to warm up the floors. So i am thinking of putting down a 1 inch thick rigid closed cell rigid insulation over the concrete floor. Then I was going to put down a vapor barrier and tuck tape both the vapor barrier and the rigid insulation seams. Over this I am thinking of putting 3/4 " tongue and groove OSB. I was then going to Tapcon a perimeter of 1" x 2" (to match the height of the rigid insulation) boards on the concrete floor in the rooms and screw the plywood sheeting to those boards, over top of the rigid insulation. The catch is I want to put tile down. I dont know if I can tile over 3/4" OSB which has been tapconed through to the concrete. I was planning on fastening the plywood through the rigid foam insulation to the concrete floor using tapcons. I know a tile substrate shouldn’t move more than a 1/16th of an inch so the grout doesn’t crack. I was wondering if there was anyone who has done this and what they would do different or if they have some suggestions. I was thinking of also putting 1 x 2 strapping every 16 in to fasten to the concrete and then fasten the plywood to the boards. But then there is the issue of the insulation not being continuous. Any suggestions? Should I Use OSB or plywood for a sub straight? Are there any better, reasonably or competitively priced insulation boards I could lay tile over IN any way. The higher the R-value the better. I want the tile job to last. This is obviously for a residential application. I could use some professional advice. I have laid a lot of tile and learned the hard way in some cases but with this I am seeking help. Thankyou. | |
