GenSpray™

GenSpray™

GenSpray™ is a rigid, froth-based closed-cell polyurethane foam system engineered for insulation, sealing, cavity fill, and flotation across a wide range of applications. Designed as a self-contained, portable kit, it provides a convenient and efficient solution for projects requiring thermal performance, air sealing, and structural support.

Developed for versatility, GenSpray™ delivers excellent thermal efficiency, moisture control, and air management while also enhancing structural integrity and reducing sound transmission. Its closed-cell foam structure ensures strong adhesion and long-term durability in both residential and commercial environments.

Engineered for ease of use, GenSpray™ systems are simple to transport, set up, and apply, making them an efficient alternative to larger, more complex spray foam equipment while maintaining consistent, high-quality results.
