SPRAY ON

Joshua Tree, CA

Spray-On House 2 is a 2,700 sq. ft. desert retreat being built in a remote site adjacent to Joshua Tree National State Park several miles outside of Pioneertown, California. The residence will be self-sustainable. Power is provided via a solar photovoltaic system of 5 kilowatts, other environmentally-friendly amenities include a water collection device, water storage tank, a generator and compost toilets. The foam application proved advantageous in this case as the foam allows for ease of transport to the remote location. The single-source building system addresses the challenges of getting large quantities of building materials and numerous subcontractors to the remote desert site, thus further reducing cost and environmental impact. This home will make use of a 5 lb. per cubic foot density foam, with steel reinforcement, A reinforced steel cage of rebar was embedded within the layers of spray foam and grounded to the site via a continuous spread footing. The materials and the building form provide high thermal mass, advantageous in the arid climate. An additional exterior coating will be applied over the foam for resistance to fire and UV exposure.
