Sill gasket for airtight drywall approach?
I am building a double stud wall house in Canada and have just finished the dense pack cellulose behind netting and preparing for ADA. I would like to use a gasket at all necessary areas (top/bottom plate, windows, doors, etc) behind the drywall instead of acoustical sealant to least interrupt the drywall installation i.e. we would put up all necessary gaskets ourselves and then the drywallers would just install as usual. Probably have them add screws every 8 inches to ensure full compression of the gasket and sealing of the joint.
So, I have looked at the price of 3/8″ x 3/16″ closed-cell, self-adhesive neoprene foam strips for sealing drywall to framing and it is going to be very expensive. What do people think of just ripping some regular sill gasket material and stapling it in place as an alternative? Much cheaper.
As well, I have just read another post and realized I could have side stapled the netting to help with the slight bulge. Do people think there will be a problem installing the drywall? Should I use 5/8″ drywall instead? I did not install drywall before the cellulose so the inspector could see the cellulose.
