Should you insulate interior walls in basement?
Walls. Basement walls should be insulated with non-water sensitive insulation that prevents interior air from contacting cold basement surfaces—the concrete structural elements and the rim joist framing. The best insulations to use are foam based and should allow the foundation wall assembly to dry inwards.
How do you insulate walls between rooms?
Soundproofing walls involves ripping the existing drywall off the walls (and perhaps the ceiling), filling the walls with fiberglass insulation, attaching metal strips called “resilient channel” to the studs, and fastening new drywall to the channel.
