Basement insulation question?
I'm halfway through a basement reno, and have all of the foundation walls lined with polyiso boards. I've used all 20ga metal framing for the interior framing, seperated from the slab with sill seal. Im about to build a partition seperating what will be the finished basement area from an unheated garage and had intended to build this with 6" metal track and stud, i have already bought all material, assuming i would insulate with fiberglass batts or whatever at 6" depth (there is no issues with water in this basement). Now i hadnt even thought about thermal bridging until this evening, given the fact its attached to an unheated space, so my question is this, If i cover the garage side of the 6" partition with a 1/2" layer of polyiso and then plywood, will this then create enough of a break to get good r value with fiberglass batting, or am i just better off eating the loss on the metal material and do it with wood framing instead, is the loss in insulation value that great using metal stud? submitted by /u/Brilliant-Use-3179 [link] [comments]
