Hello fellow DIY'ers, I am renovating my 1920 home in the Washington, DC area and I ended up completely gutting it so that I may properly seal and insulate it. My question is, with regards to its original dutch lap siding, should I seal each and every joint with construction adhesive? Another concern is: at some point, presumably between 1938 and 1989, the former owners put felt over the dutch lap and resided with wavy asbestos shingles. After I wet spray cellulose into the cavities, I plan on using construction adhesive on the stud and plate faces to seal to the drywall and where the wall meets the ceiling. Will all of this lead to moisture being trapped, eventually dry-rotting the original dutch lap siding? Thanks for any insight you can provide!

Someone has this insulation and wants to give it to me for my garage. Can anyone tell me what it is? I've never seen any like this before and couldn't find any like it on the web? Is it asbestos? Thanks.
