Is $2,400 to blow in rockwool insulation to R38 in garage ceiling a fair price?
Project Details
I have a bedroom over an unheated garage that is always 7-8 degrees warmer or colder than the hvac set temp. The ceiling now is R19, the minimum required by code. It's the only room in the house that has a temperature differential because the air from the space below it makes its way through the thin layer of insulation in the garage ceiling.
