Bldg/construction Question

[GGB]

I recently finished out the remaining area of our basement. I also used 2 x 4 stud walls with pressure treated plates, placed about 1/2 " off of the concrete walls. I then had an insulation company spray a 1 1/2- 2" layer of closed cell insulation directly on the concrete and behind the stud walls, followed by spraying cellulose out to the front of the studs. It cost about $1900 to cover 1100 + square feet, including spraying extra thick around the sill plate.

This is the most comfortable area of our home, and has me totally sold on using this method. I wish my whole house was done this way, but we didn't build it.

Spray foam or foam panels are good options.

If this is air conditioned space, that would really help prevent mildew and mold.

When adding A/C / heat to a den/room, you also need to add a return to the room. The return is what takes care of the humidity (so to speak). I've seen a lot of people just cut a hole in the duct to supply A/C & heat but, don't add a return

I do have a 1/2 to 1" space between the block wall and the framed wall.

you can insulate using rigid foam products and build your wall in front of it.

This is best option - otherwise use spray foam but that is more expensive
