I removed paneling from my basement to discover the studs were all 2x2 secured to the basement wall. My questioned is do I leave the 2x2 on the wall and add another 2x2 to increase the width of the stud so 4" insulation can be added or do I remove the 2x2s and replace with 2x4.
I received many answers to resolve this problem, I'm not sure what the right one should be.
Hi take it al off. The proper way u should have an air barrier behind your studs. Second you should have at least 1"-2" behind the studs for air movement. You already have it all open do it right it will cost you more money if you have to open it up in the future ...
If it was never insulated before it will crack the first winter it sees if you just insulate.
it best to do some water prevention first then insulate with insul foam board by glueing to walls and stud in front with 2x4 walls.
will also support the house for added safety if mounted to joists and anchored to floor.
