Closed cell foam is a spray applied polyurethane foam that expands 30 x its liquid volume. It utilizes an inert gas blowing agent that is trapped in the cell structure of the foam allowing for an R-value of approximately 7 per inch or more. It contains no formaldehyde and shows no levels of off gassing.
Closed Cell SPF does not allow water to pass through it and is approved by FEMA (Federal Emergency Management Agency) as a flood-resistant material. Closed Cell SPF would also be a good choice where small framing sizes need added structural integrity and the greatest R-value per inch possible.
