How to keep heat out of a house in a hot desert using open cell spray foam insulation
Our team recently worked on a new construction single-family residential home in Dragoon, Arizona. On average, there are 284 sunny days per year in this part of the country and high temps in July are around 95 degrees. The homeowner wanted their home to have a tightly sealed building envelope to allow for the least amount of heat transfer from the exterior of the home to the interior.
The Solution: Open Cell Spray Foam Application
Here are some highlights of our open cell spray polyurethane foam installation:
- The home required 8.3 inches of foam installed over 3,454 square feet in the attic roof deck
- The home required 5.5 inches of foam installed over 3,000 square feet in the exterior framed walls
- The insulation install of the house was completed in 2.5 days and used approximately 84 inches of the open cell spray foam product
How to Keep Heat out of a House
By sealing off the eaves and encapsulating the attic roof deck, this allows the hot air from outside of the home to stay outside and the air conditioning to work less by staying cool in the attic space. The walls were sprayed to close up all the exterior gaps and penetrations that were created during the building of the home and also to keep the hot desert heat from penetrating through the walls. By creating this sealed envelope the house will be airtight which cuts down the chances of mold growth significantly. Without air transfer from hot to cold there is less moisture, therefore less of an opportunity for mold to grow.
With this application and the design of the house, it will achieve a much cleaner, safer, and more energy-efficient home for as long as the home exists. The foam doesn’t break down over time as fiberglass does, which allows a lifetime of maximum heat resistance along with comfort and energy savings.
