Which insulation? Photos attached of room
Insulation is sized by stud size and spacing i.e; 2x6- 16" is used for a wall built with 2x6 studs and spaced 16"on centre.This is important so you don't compress the insulation when you install it, which lowers the r value. The paper is a vapour barrier, it depends on where you live whether you need one or not. I like Roxul insulation myself but I think its hard to find in some parts of the U.S.
