Insulation Material Costs??
I have found insulation (kraft faced r-13 batts) to be about .24 per square foot (HD big box store), R19@ .46, R30 @ .77. We also have to do some rigid(r30) due to space contraints and that stuff starts getting expensive.
I just got a bid to insulate my house (approx 2k foot remodel). Insulation dude says $2003 (delivered / installed). I priced the material the best I could at HD and came up with about $1700+. I asked the company how much for just the insulation....just under 1600, not delivered. They'll do it in about a 1/2 day, it would take me "longer". I will however miss out on the inhalation of the fiberglass particles.....
