Attic Exterior Perimeter Top Plate Air Sealing & Insulation – A Challenging Detail to Get Right

The area where the exterior sheathing, top plate, drywall, and soffit/eave ventilation intakes all come together is a challenging area to effectively air seal and insulate. Fortunately, there are tools and products on the market that can make it easier to effectively air seal and insulate this tight area. The presentation will cover the different common ways this tight area is put together and what to do in each situation. Additionally, the presentation will show how raised heel trusses solve the problems encountered in this area when standard framing/trusses are used.
