Froth-Pak™ 630 is a high-capacity, professional-grade closed-cell spray foam insulation kit built for larger jobs that require greater coverage and long-lasting performance. This two-component system is designed to seal, insulate, and create a continuous air barrier across a wide range of applications. With a theoretical yield of 630 board feet (at 1” thickness), this kit is ideal for contractors handling larger projects such as full-room insulation, extensive air sealing, or multi-area jobsite work.
The closed-cell foam expands and cures into a rigid, high-density insulation layer, helping block air movement while also adding strength to the structure. With an R-value of approximately 6.2 per inch, it delivers strong thermal insulation while helping reduce moisture intrusion, mold growth, and airborne allergens. Froth-Pak 630 features an ergonomic dispensing system designed for consistent, on-ratio application with minimal waste. Its flexible hose and controlled output make it easier to cover larger areas while maintaining precision. The fast-curing formula allows for efficient installation and jobsite turnaround, with re-entry possible after about one hour when properly ventilated.
