The initial cost of using spray foam insulation is more than conventional insulation, however the savings offset the costs by far. It can cost 1.25- 2.25$ per Sq ft. The savings repay the initial costs by around 3-5 years, depending on the amount of insulation used. Initial Isocen cost for you, broadly, would be $4200. I have seen Home Depot installing blown in insulation for around a $1 per Sq ft, or $2400 for your place A difference of $1800. This is based on online, unverified info.
