Hi everyone I joined to maybe get some help on my basement project. I have a room under a carport that we weren't using due to the very cold nature of this room. The room size is 24'L x 13'W x 7'7"H. I want to use this room for a workshop to build my model boats. I have painted/sealed the walls for moisture, then bought some 2 inch thick owens corning pink rigid foam insulation. I have it all cut to height and in place. Now from here I don't know exactly how to proceed. I thought I would cut out places for 2x4's to fit face flush with the foam, then screw them to the block wall. But if I do that I would only be leaving 1/4 of an inch of foam under the 2x4 and I am sure this thin part would break off and leave my insulation loose. I would also have to buy 2 3/4 inch concrete screws to put the 2x4's in place. So now I am thinking of buying 1x3 furring strips and maybe glueing it to the block wall with an adhesive, then placing the foam in front of that and nailing panelling to the strips. That would give me a bit of air space between the wall and the foam. It would also leave the insulation solid top to bottom. I don't know for sure if an adhesive like Liquid nails would do the job and allow me to nail up panneling to the strips through the foam? I need help to figure out what to do. I sure don't want to do this more than once. And I want to do it right the frist time out if I can. So please help me if you can.
