Provide flashing and sealing integrated with the air and water control layers for vents and other roof penetrations
Image
Right - Continuous wall sheathing and blocking has been installed to brace the raised heel trusses.
Image
Right - Foil-faced polyisocyanurate insulating rigid foam sheathing is installed below the floor framing of this house built on piers; however, the seams should be sealed with metal taped and the plumbing elevated and protected.
Image
Right - Foil-faced polyisocyanurate rigid foam is attached to the existing exterior wall with vertical wood furring strips
Image
Right - Open-cell polyurethane spray foam to R-28 on underside of roof turns new attic into conditioned space for HVAC.
Image
Right - Spray foam insulation has been sprayed onto the underside of the sloped roof and the gable end wall to provide a sealed, insulated attic for housing the HVAC ducts
Image
Right - The basement foundation is insulated on the exterior and termite shield extends out past the top of the insulation.
Image
Right - These raised heel roof trusses provide 16 inches of space over the outer walls for full insulation coverage at the attic perimeter.
Image
Right - This foil-faced polyisocyanurate rigid foam is installed on an existing exterior wall and the seams are taped so the rigid foam can serve as a water control layer
Image
Right - This new sealed attic has 5.5 inches (R-20) of spray foam insulation along the underside of the roof deck providing a conditioned attic space for the heating and cooling ducts.
Image
Right - XPS foam insulation is attached to the existing exterior wall with wood furring strips that serve as a nail base for the siding and are installed vertically to allow for drainage and drying behind the siding
Image
Image
Right – Closed-cell polyurethane foam is sprayed on the underside of the roof deck to provide structural connections and seal seams in the sheathing to increase wind resistance
Image
Right – Furring strips provide a drainage and ventilation gap between the siding and the cork insulation.
Image
Right – Furring strips provide a drainage gap between the rigid foam and the siding.
Image
