Re: Ductwork Insulation
Before you insulate the ducts, you'll want to apply duct mastic to all of the seams and joints to seal them up. It's made just for that purpose. The easy way to apply it (so I've heard) is to don some rubber gloves and just smear it on with your hands.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
