If you’re curious to learn a little more about the technology behind spray foam insulation, let Evergreen Foam & Insulation be your guide as we take a look at what spray-applied polyurethane foam insulation actually is.

Spray foam insulation is:

  • 100% water blown open-cell spray foam
  • A mixture of two components - isocyanate and a specially formulated resin
  • The separation of isocyanate and a specially formulated resin until application where they are mixed together at gunpoint using high pressure, high temperature specialized spray application equipment

Isocyanate is the base component of many plastics. When combined with a reacting agent or resin and then applied to a roof deck, wall or crawl space surface, spray foam rapidly expands to fill and adhere to all voids in the applied area. This has the effect of sealing out the outside air and sealing in the conditioned air of a structure

Spray Foam's, air barrier performance characteristics effectively mitigate energy loss affecting floors, walls and ceilings. Spray foam also helps mitigate energy loss from HVAC by sealing on conditional air within the building.

Why spray foam insulation from Evergreen Foam & Insulation makes sense

  • The U.S. Department of Energy states that a building’s floors, walls and ceilings are the largest single contributor to energy loss
  • Spray foam insulation helps seal all of these areas to guard against air infiltration and energy loss
  • Traditional insulation allows air to penetrate and pass through gaps and seams in floors, walls and ceilings with ease
  • Convective air currents are created in wall cavities and attic spaces using conventional installation materials like fiberglass causing energy lost
  • The performance of traditional insulation is drastically reduced by the infiltration of air
  • Only spray foam provides a certified air barrier to these drafts
