Can I not add pictures to post here? I can't seem to find the option

So the studs are nailed to the concrete wall. What do you recommend to take them out?

What do you mean run them crosswise?

I'm in Missouri so Temps can get cold to hot

88

They are nominal 1.5 x 2.5

That's a good idea

It's not a load bearing wall, but the studs are tapcon to the concrete wall. The spaces are 24" on centre. I found some, they're just a lot more expensive

I've been pricing things out and you are right. I think I'm going to do rigid foam and just cut it to size around the framing and used spray foam for any gaps.. I have about 88 sq. ft and the price is around $224 for 2in....What do you think about 1 1/2 inch?

It's a wall in a basement laundry room. The wall is a concrete foundation wall that has some 2x3 framing on it already

Who is Jon?

I was thinking about that too

I'm not opposed to it, but that does sound a bit complicated and expensive. I'm looking to see if I can insulate this 1 wall for about $100 or less
