Spray Foam is a two-component mixture that is combined at the job site and sprayed onto the substrate by a certified spray foam engineer. Expanding on contact to form a solid, slightly porous foam, this insulation material adheres to the surfaces of the surrounding building materials, sealing all gaps and forming moisture and vapor barriers. It can be sprayed onto concrete slabs, into wall cavities, or against the interior side of sheathing.
Open-cell Spray Foam cures in seconds as it expands to 100 times its liquid volume. Closed-cell Spray Foam cures in approximately 2 minutes and expands to 30 times its liquid volume. The type of home, its building materials and its age along with local weather conditions will all be considered with regards to Spray Foam Insulation.
Required spray foam equipment elements include a plural component proportioner pump with heaters, dual high pressure heated hoses, high pressure mixing spray gun, feed pumps, an air compressor, and an electrical generator. Typically for new construction, small areas and buildings under 14 stories, we use our mobile spray rigs, eliminating the need for transporting and using outside equipment.
