Most open cell foam has a density of about 5 pounds per cubic foot.

Closed cell spray polyurethane foam.

The description closed cell comes from the cell structure of the finished insulation material. Reduced uncontrolled air leakage results in lower utility bills and reduced greenhouse gas emissions. A 2 component polyurethane spray foam roof system permax 3 0 hfo closed cell foam insulation permax 3 0 hfo is a 4th generation low global warming potential 2 component polyurethane spray foam roof system consisting of resin components a and b which when sprayed through plural component spray equipment will produce a premium seamless monolithic and durable closed cell polyurethane foam. Closed cell foam is much denser than open cell foam.

The cell designation relates to vapor control. The blowing agent provides a more effective thermal barrier than air leading to higher r values compared to other insulations. Closed cell spray foam insulation is one of the most efficient insulating materials commercially available with aged r values above 6 0 per inch. Closed cell spray foam provides a higher r value per inch 6 5 than less expensive insulation types like cellulose and fiberglass 3 5 to 3 7.

The 2 lb ft 3 high density foam is also referred to as closed cell spray applied foam and the 0 5 lb ft3 low density foam is also referred to as open cell. Basf manufactures both closed cell and open cell spray polyurethane foam products for residential and commercial construction providing the right spf system for any type of well engineered building envelope. Multiple immediate passes with no wait time may also be applied. Closed cell foam uses the same suspended bubbles in a polyurethane matrix as the open form but the bubbles are filled with a blowing agent.

Closed cell closed cell is a two component medium density one to one by volume spray applied polyurethane foam. Most spray polyurethane foam is called two component foam. Polymer planet liquid urethane 2 part closed cell rigid pour foam 2 lb density fast acting formula great for boat buoyancy flotation filling soundproofing insulation 1 gallon kit total. High density closed cell spray polyurethane foam is typically 2 lb ft 3 whereas low density open cell spray polyurethane foam is 0 5 lb ft 3.

Closed cell foam can be over three times that with a density of 1 75 pounds per cubic foot or more.
