Attic-Wall Insulation with SPRAY-FOAM – Durham, NC

6/9/2011 – Agreement to Air-Seal and Insulate Knee-Walls with 2″ of Spray Foam.
Address Dryer Vent+Bath Vent, Replace. Crawlspace Door

6/16/2011 – All items complete.

SHS maximized the spray-foam, by using small sections of air-barrier to fill gaps prior to foam.

The new layer of closed cell foam is approx 2″ thick and continuous from the roof deck above the knee-wall to the ceiling surface below the knee-wall, and all of the studs were covered intentionally to minimize thermal bridging.
Enjoy the photos! This should be a happy tenant!

Other notes. The roof deck itself is nearing the end of its useful life. When it becomes necessary to replace the roof, I would recommend completely removing the roof deck, applying insulation from above in a way that forces the product in contact with the ceiling surface(rather than the roof as it is now) and then installing the new roof system.
Below the home there is an uninsulated crawlspace; SHS recommends the installation of a sealed vapor barrier to minimize the ground moisture. This should be done after the termite treatment. After the vapor barrier is in place it would be time to insulate the floors(after floor penetrations are air-sealed) or seal the crawlspace by insulating the walls, band, door, and sealing the vents. [The equipment under the home is not combustion equipment.] A drying mechanism is required for all sealed crawlspaces.
