Spray Foam Insulation

Spray foam insulation is a popular choice in insulation for several reasons:
Spray Foam Insulation - Delmarva Spray Foam
  • Applied as a liquid, spray foam insulation expands to 100 times its volume in seconds to fill every crack and crevice. 
  • Spray foam insulation remains flexible and after installation the integrity of the building envelope seal remains intact over time. 
  • Spray foam insulation acts as a complete insulation and air barrier to minimize air leakage and seal the building envelope for optimal airtightness.

  • Although many homeowners choose to use spray foam throughout their entire home, in many cases spray foam insulation is also used for air sealing. This is a perfect solution to keep conditioned air in the home, as spray foam insulation easily expands to fill penetrations where conditioned air can escape.


Open-cell spray foam is soft. The walls (or cells) of the bubbles are broken, and air fills these spaces. This makes the foam soft and pliable, similar to a rubber ball. The R-value of the insulation is related to the value of the air inside these broken bubbles. Open cell insulation density is up to one pound per cubic foot.

Closed-cell spray foam is solid, as the cells of the bubbles remain intact, which makes the product rigid. The cells are filled with a gas that makes the R-value higher than that of open-cell foam. Closed-cell foam has varying degrees of hardness, depending its density, but is typically 1.5 pounds to 4 pounds per cubic foot.
