Bryan Kwater Posted: Apr 04, 2008 09:22 AM	best way to foam scissor truss I am bidding a large residential job that has 2' high scissor trusses in part of the building. There's not enough room for access to foam on top of the drywall, and an unvented attic is not an option for this building. What do you suggest for a method of installing closed cell foam in this scenario?
