Closed-cell

Closed-cell spray polyurethane foam (SPF) is one of the most advanced insulation solutions available, providing nearly twice the R-value of open-cell foam per inch and superior energy savings. This dense, polyurethane foam insulation is extremely durable, expanding and fully adhering to surfaces, strengthening the structure of buildings.

It provides incredible thermal performance and can be installed in areas that would be inaccessible or difficult for other forms of insulation. By effectively isolating air currents and moisture, it increases the comfort and life of buildings. Closed-cell spray polyurethane foam insulation can only be installed by a trained and certified professional.

After the closed-cell foam insulation is sprayed in, it requires the application of an ignition or thermal barrier. All fire protective requirements detailed within Section 2603.4 of the IBC are mandatory.
