Depends on where you live and local building codes, but r20 is typically the minimum. Guess if the inspector is picky, you could install 1/2 xps board over the walls and then drywall, probably have to move electrical boxes out another 1/2 last edited by drthorne on oct 5th, 2019 9:25 pm, edited 1 time in total. The larger the r value, the better the insulation value.
Fill ‘Er Up.
A better question to ask is, what r value is optimal for my home? The canadian wood council’s wall thermal design calculator has been developed for information purposes only.
