If you're stuffing r-19 into 2x4 walls, you're wasting your money.

Hi,

My contractor told me to use R13 insulation on the walls framed out by
2x4's. He said that it won't fit thinkness-wise, but I would be able
to compress it with drywall. Does that sound like good advice?

Many thanks in advance,

Just my opinion, but I use R-19, and while I have no way to measure it
for insulating value, it does a good job of keeping the cool in in the
summer and the warm in in the winter.
The reason it works IMO is draft stop, filling the cavity completely
works better (again IMO) than having a little something flopping
around not even touching the studs, which is usually the case with R13.
