What air-seal caulks/sealants are now available?
What caulks and sealants are currently available and recommended for air sealing walls and ceilings during construction?
My cabin is not new but I am stripping it to the studs and also installing new trusses, windows and doors. There will be 2 inches of XPS foam on the exterior and mineral wool in the 2 x 4 walls. Also 10 1/2 inches of mineral wool on the attic floor.
Is sealing the XPS with tape enough or should I also seal the OSB and all two-by joints with sealant? I want to use a sealant that will remain flexible and maintain a lasting seal.
Thank you, Tony
