Insulating - Rim/Header Joist - Basement
I searched the forums and wasn't able to gather the ideal way to do what I want.
We have an unfinished basement that is always cold, generally between 55 and 58 degrees. This results in the first floor floors being cold regardless of the temperature up stairs.
I am considering buying a DIY spray foam kit to spray 2" of foam on the rim/header joist. When I put my hand up there now, I feel cold air coming in...(not just radiating in). My infrared thermometer shows that this area is about 20 degrees warmer than the outside temperature.
This house has a basement that is 52' x 31' and has 2x12s as the floor joists. The basement is poured walls and the exterior is brick down to the top of the basement wall.
Is using spray foam the best option here vs hard foam board or batted insulation? Is it worth the cost?
I live in Southern Ohio.
I've seen the soyfoam product, as well as sprayfoamdirect and other suppliers and while itappears it may cost around $600, it should qualify for the 30% tax credit offered this year for insulation.
