Spray Right Louisiana applied Sealection 500 spray foam insulation to the attic of an existing home in Alexandria. The roof deck was applied with 5 1/2 inches of Sealection 500 covering the stud face.
Foam insulation was applied directly to the roof deck in order to create a tight bond between the roof sheathing and the roof joist structure while increasing the home's energy efficiency.
Another spray job to a new construction home in Alexandria Louisiana; we applied Demilec Sealection 500 spray foam insulation. It was applied at 5 1/2 inches to the roof covering stud face and 3 inches to the exterior walls of the home as well as the garage.
Homeowners also decided to install an insulated garage door to the garage in order to create a conditioned area for a work shop.
By creating a complete seal with Sealection 500, the homeowners received a tremendous return on their investment. Air leakage was reduced to an absolute minimum, and the size and cost of the HVAC equipment was lowered. Savings are predicted to be as high as 50% when compared to conventional insulation. No more high utility bills!
Other spray foam insulation job at 5 1/2 inches (R-21+) to the roof deck (covering stud faces) of a home in Alexandria, LA. The walls and gable ends were also insulated at 3 1/2 nominal inches (R-13) with Demilec Sealection 500.
By applying the spray foam insulation to the underside of the roof deck instead of the floor of the attic, it effectively extended the home's envelope to include attic space. Because this house was insulated with Sealection 500 spray foam in the walls and roof, creating the un vented attic space, it will have the lowest attic temperature ever achieved for a stick built construction. The un vented attic assembly will maintain a delta of only seven to ten degrees warmer temperature than the air conditioned space below. Sealection 500 foam will reduce the heat load on the house and its HVAC system and ductwork, dramatically changing the overall performance and comfort of the home.
With Alexandria so close to the coast line, closing soffits, gable and ridge vents, helps prevent moisture laden outside air from entering the attic and the home or building and serves as a barrier to wind driven rain. Demilec Sealection 500 spray foam insulation has been rated to withstand gust wind conditions up to 160 miles per hour. Water entering homes through soffits and gable vents proved to be the second highest cause of property damage from Florida's Hurricane Charlie. As a result, the Florida Hurricane Advisory committee has changed building codes to support the use of un vented attics.
