Best way to insulate attic of new addition?
I have a new mud/laundry room addition to my house. I’m in central NY. It’s 12’x22′ with a hip roof built with trusses. I was wanting to use closed cell foam for the under side of the roof deck. The ceiling will be drywall. I was wondering if this would be OK? Do I need to supply any heated or cooled air to that attic area? Would a vented attic be OK instead although insulating it would be very difficult.
I’m also considering spraying the walls which are built with Zip R-6 panels. Any and all help would be greatly appreciated. Thank you.
