Thanks for all the help, previously. I have one more thing that you guys can help me with. Actually there are a lot more, but right now, this one...lol...

I'm getting ready to insulate the outside walls in my bathroom reno...so do I use craft paper backed fiberglass, or unbacked fiberglass and 6 mil plastic...taped.

Just wondering...

Gutted down to the studs...with exterior plywood sheathing and then brick.

Seal any seams or gaps in the plywood to avoid air movement or vapor push from outside.

Insulate with high density batt or better yet, roxul. Make sure your drywall is airtight.

No vapor barrier required.

Make sure your bath is vented properly.

Venting is via an oversized exhaust fan. The plywood is in good shape. I haven't been able to find any gaps to seal.

I was just wondering why no vapor barrior...if so, then why the craft paper insulation product.

BTW...thanks for your input. Ed

Not really indicated for your climate. Your vapor control recommendations can be supplied by painted drywall.

Make sure your drywall approach is air tight.

Bathroom insulation advice...

Thanks...looking in to the Roxul solution. Expensive, but in light of not needing a vapor barrier...I like it so far.

Thanks, Ed
