BEEST FullStop Spray Foam Insulation Kit, 240 Board Feet, 12 Cans, Class A Rated

BEEST FullStop is a spray foam insulation kit for sealing and insulating walls and attics, delivering up to 240 board feet and an R-value of 8.24 at 2 inches (5.08 cm) thick.

• Tested to ASTM E84 with a Flame Spread Index of 0 and Smoke Developed Index of 120 — meets Class A surface-burning criteria.
• Includes 12 foam cans, a Pro X applicator gun, one solvent-based cleaner, gloves, goggles and a coverall — supplies a complete DIY application setup.
• Moisture-cured hybrid polyurethane foam with short-term water absorption tested under EN 1609 — fills gaps while helping resist water absorption.
• Bonds to wood, metal, drywall, concrete and brick — seals common building surfaces.
• Recommended application temperature is 68–77°F (20–25°C) — supports consistent expansion within that range.

FullStop is made for insulation work where gaps, cracks and hard-to-reach spaces can allow air movement and heat transfer. Use it in walls, attics and other suitable areas of a building to create an insulating seal. The foam is intended for thermal insulation and soundproofing, with its R-value providing a concrete measure of thermal performance.

What insulation and surface-burning performance does FullStop offer?

At 2 inches (5.08 cm) thick, BEEST FullStop has an R-value of 8.24. Its ASTM E84 test results are a Flame Spread Index of 0 and a Smoke Developed Index of 120, meeting Class A surface-burning criteria. These figures help buyers compare its thermal insulation and surface-burning performance for building projects.

The foam is also designed to help limit drafts by filling openings and reducing unwanted air movement and heat transfer. FullStop is intended for thermal and sound insulation; no acoustic rating is provided here.

• Designed for gaps, cracks and hard-to-reach spaces.
• Helps improve year-round comfort by reducing air movement and heat transfer.

What comes in the BEEST FullStop insulation kit?

The kit contains 12 spray foam cans, one solvent-based cleaner, a Pro X applicator gun, gloves, goggles and a coverall. Together, these components provide the foam, application equipment, cleaner and protective gear for a DIY insulation setup. The foam yield is up to 240 board feet; the actual coverage depends on the application.

The included cleaner is solvent-based, and the applicator is a heavy-duty gun. The gloves, goggles and coverall are included as part of the kit, so the listed contents extend beyond the foam cans alone.

• 12 spray foam cans.
• One Pro X applicator gun and one solvent-based cleaner.
• Gloves, goggles and a coverall.

Which surfaces and application conditions suit this foam?

BEEST FullStop’s moisture-cured polyurethane formula bonds to wood, metal, drywall, concrete and brick. Apply it within the recommended 68–77°F (20–25°C) temperature range, where it expands consistently to fill spaces and form an insulating seal after curing.

Its hybrid foam combines strength with controlled expansion for gap filling and coverage. Short-term water absorption was tested under EN 1609, and the cured foam structure helps resist water absorption. For best fit, plan the application around the stated temperature range and the building surfaces being sealed.

• Compatible surfaces include wood, metal, drywall, concrete and brick.
• Moisture-cured polyurethane formula.
• Expansion is described for the recommended application temperature range.

FullStop suits DIYers and building projects that need a spray-applied insulation seal for walls, attics, gaps or cracks, along with the core application equipment and protective gear in one kit. BEEST is an American family-owned company with U.S.-based support for application questions, product guidance and technical support. For buyers seeking measured thermal performance and Class A surface-burning results, this kit combines an R-value of 8.24 at 2 inches with ASTM E84 test results.
