XPS Insulation Questions
Hello All, I am just starting to finish off a smaller basement and have searched and read a great deal on here about XPS. Yesterday I bought all the 1.5" board I am going to need. I plan to install this, then a 2x4 stud wall tight to it with unfaced FG in the stud wall. A couple questions though.
1. I see on the Building Science literature they recommend XPS on the inside of the rim joist if it is not installed on the exterior. Is this something that can make or break the project? The builder has unfaced FG insulation in there now.
2. I bought Tyvek tape to seal the seams panel to panel, and some Loc-tite for adhering to the wall. My question is what is appropriate to seal between the top and bottom of the panel and the concrete? I bought expanding foam, but I have heard people say caulk on this forum. If anyone can give a specific product recommendation, that would be appreciated.
Thanks alot for any responses
