Image
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
Image
Image
Image
Raised heel energy trusses extend past the exterior wall and are deeper at the wall allowing room for full insulation coverage over the top plate of the exterior walls.
Image
Image
Image
Right - Continuous wall sheathing and blocking has been installed to brace the raised heel trusses.
