Re: How to insulate inside wooden walls
I agree with GregC --- touchy situation.
However , I disagree with GregC in that cellulose is treated with a Borax solution to prevent mold and inhibits termites.
Also with fiberglass there still is a chance with mold occurring --- while the fiberglass itself is not food for mold it's organic material and moisture that is trapped within the fibers or contact with the wood structure and drywall which promotes mold.
The touchy part of this situation is the acceptable method of vapour control.
Depending on regions some practices are to allow pass through breathing. In other words the home will breathe to the outside and to the inside depending on weather . If the primary concern for conditioning is cooling then breathing will occur to the inside since the dehumidification is done by the A/C. When heating is secondary the breathing will occur to the outside.
In hot and humid areas where cooling is the main conditioning and little to no heating requirements then vapour control is done to the exterior and the breathing occurs to the inside with the A/C dehumidifying.
Generally --- in northern winter climates where heating is a primary conditioning and cooling is secondary --- vapour control is done to the interior.
If you are unsure as to what method is appropriate to your area contact your municipal building department for their advice.
