Reply to comment by Joecool2008 in How to insulate 24" stud spacing with 2x3 framing? by Blackking203

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

Insulation is hard to do nowadays less than a 100. Might get foam board and cut it down.

I was thinking about that too

A serrated knife cuts it well. Or, Home Depot has some pink board with perforated lines to allow for easy sections.

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?

Make sure you cut the insulation about 1/4" short on all sides. That will leave a nice gap to fit the spray foam in.

Since I don't know the temperatures around your parts, I would be looking at the R values. But, 1 1/2 board does a decent job.
