Paula writes from Beech Grove, Indiana: "We are replacing wood paneling in our basement with new paneling and would like to insulate behind it. Can you use foam board insulation, and does it have to be covered over with a fire retardant such as gypsum board before the paneling can go back up or can it go directly over it?"

Answer: FOAMULAR® or INSULPINK® insulation will work nicely in your basement. Yes, it is recommended to cover the insulation with a fire-rated board after installation.
