Honeyfoam HF600 Closed Cell Spray Foam Kit 2 Part Foam Sealant 600 Board Feet

Stop energy leaks before they drain your wallet. Honeyfoam 600QR Spray Foam Kit is a premium closed-cell insulation system designed to seal gaps, block drafts, and improve year-round comfort. Its quick-rise formula expands into cracks, seams, and hard-to-reach spaces, then cures into a dense, rigid, airtight insulation layer. With approximately 600 board feet of coverage, R-6.2 per inch thermal performance, and ASTM E84 Class A fire rating, Honeyfoam 600QR gives homeowners and contractors a strong, long-lasting solution for insulation, air sealing, and energy efficiency.

Unlike fiberglass or loose-fill insulation that can leave gaps around framing, rim joists, attic edges, crawlspaces, basements, garages, and wall cavities, Honeyfoam expands in place to fill cracks, seams, and hard-to-reach areas. Once cured, it forms a strong insulation barrier that helps improve your building envelope and supports long-term energy efficiency.

With approximately 600 board feet of coverage, the Honeyfoam 600QR is ideal for larger insulation projects where performance, speed, and durability matter. The quick-rise formula expands and cures rapidly, helping you complete jobs faster while creating a strong closed-cell foam layer with excellent air-sealing performance.

Honeyfoam 600QR is ASTM E84 Class A fire rated and provides an R-value of 6.2 per inch, helping reduce energy loss while adding a durable layer of thermal insulation. Its closed-cell structure also helps resist air infiltration and moisture-related issues when properly applied, making it a smart choice for basements, crawlspaces, garages, attics, rim joists, metal buildings, and renovation projects.

The kit comes ready to use with included PPE and maintenance supplies, giving you the essential items needed to start your project with more confidence.
