TYPES OF FOAM
Closed Cell Foam
Closed cell foam ranges from 1.7 pounds per cubic foot to 10 pounds per cubic foot and is durable enough to walk on. It is a tough, adhesive foam that uses non-ozone depleting refrigerant gas as its insulating medium. This property allows closed cell foam to obtain R-values up to 7 per inch, which is the highest of any insulation in the construction industry.
Closed cell foam provides a seamless air-barrier at just 1 inch, a class II vapor barrier at 1.5 inches, and it tenaciously adheres to any clean substrate. It can even make a wall 2 to 3 times stronger. These properties make closed cell foam the most versatile insulation product in the construction industry. Closed cell foam works well interior or exterior, and it’s the only insulation material that continues to perform during and after being submerged under water.

Open Cell Foam
Open cell is a light-weight foam weighing only ½ pound per cubic foot. By comparison, it would be somewhat similar to dry angel food cake. Open cell foam is filled thruought with small bubbles of air and tops out with an R-value of 3.9 per inch after the first inch.
Open cell foam provides a seamless air-barrier at 3.5 inches and never settles. Open cell foam has a lower cost than closed cell foam and provides comparable thermal efficiency in many indoor applications.
