Closed Cell Spray Polyurethane Foam

To produce closed cell requires the use of an a component iso and a blended b component resin which contains zero ozone depleting blowing agents catalysts polyols and fire retarding materials.

Closed cell spray polyurethane foam. As an industry leader in high performance spray foam insulation lapolla strives to raise the bar in energy efficiency and sustainable building practices. Multiple immediate passes with no wait time may also be applied. The description closed cell comes from the cell structure of the finished insulation material. 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 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. 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. 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. Closed cell foam can be over three times that with a density of 1 75 pounds per cubic foot or more.

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. Reduced uncontrolled air leakage results in lower utility bills and reduced greenhouse gas emissions. Closed cell foam is much denser than open cell foam.

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. 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. Johns manville corbond iii closed cell spray polyurethane foam insulation offers and r value of r 7 per inch and can be applied in a single pass to a maximum of 3 5 inches providing superior thermal performance with seamless air sealing and moisture control in a single step. 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.
