ENVELO-SEAL™ spray applied polyurethane foam is a two component, medium-density, structural insulation system designed for commercial, residential, and industrial applications.

Closed-cell polyurethane foam yields a high R-value.  Minimizes air and moisture infiltration.  The spray applied nature of ENVELO-SEAL™ SPF allows for tremendous sealing properties which contribute to healthier homes and workplaces.  The rigid nature of ENVELO-SEAL™ increases overall structural integrity resulting in more durable structures.  ENVELO-SEAL™ expands during application to provide increased performance values by sealing the building envelope.

The ENVELO-SEAL™ system is comprised of an “A” component or aromatic diisocyanate, and a blended “B” component which includes polyols, fire retardant materials, catalysts, and non-ozone depleting blowing agents.
