What is the highest rated wall insulation?
Closed cell foam has the highest R-value of any insulation, around R-6.2 per inch, but can be expensive; open-cell foam insulation values are around R-3.7 per inch of thickness.
How do I estimate wall insulation?
Measure the height and width of any windows or doors in the wall. Multiply the measurements to find the area of each window or door, and subtract them from the total square footage of the wall. This gives you the square footage of insulation you need for that wall.
Is roll or batt insulation cheaper?
There is little to no price difference between batts and rolls, and both come in the same ranges of heat resistance values (or R-values). Though you may be anxious to get started, I urge you to spend a little time learning about the differences between the two in order to, hopefully, choose the right one for you.
