Spraycoat Fire Rated Spray Foam Insulation Kit 18 Pack - 360 Sq.Ft

Our review of the Spraycoat Fire Rated Spray Foam Insulation Kit (18 Pack) finds it best for homeowners, contractors, and marine technicians who need a durable, high-performance closed cell spray foam that also carries a Class-A fire rating. The single biggest reason to buy is its combination of flame resistance and energy savings: the formula is ASTM E84 Class-A rated and promises significant reductions in heating and cooling costs when applied correctly. This kit is aimed at projects where a rigid, long-lasting seal and strong adhesion to diverse substrates are required.

Key Features

• Class-A Fire Rated: Provides enhanced flame resistance for safer insulation in roofs, walls, basements and tanks, meeting ASTM E84 expectations for surface burning characteristics.
• Energy Saving: Closed cell polyurethane reduces heat transfer and can lower heating and cooling costs substantially when used to seal cavities and thermal leaks.
• Long-Lasting Durability: Cures to a rigid, dense structure that resists cracking, shrinking and settling to preserve insulation performance over time.
• Dual-Nozzle Application: Includes two interchangeable nozzles for vertical surfaces and ceilings to improve control, reduce dripping and enable paintability after cure.
• Wide Surface Compatibility: Adheres to drywall, wood, concrete, metal, PVC and more, allowing use across residential, industrial and marine projects.
• Cleaner Included: The included foam gun cleaner is effective for maintenance and was reported to clean as well as soap and water by some users.

Who It's For

The kit is aimed at installers and advanced DIYers tackling larger insulating projects where fire performance matters, such as attic conversions, basement sealing, commercial walls and marine vessel gaps. Professionals will appreciate the 18-pack supply and the dual-nozzle system for directional control on ceilings versus walls.

Those who should look elsewhere include casual homeowners who need only a small patch or who are uncomfortable with pressurized spray foam application; a smaller one- or two-can kit or a professional applicator service might be more suitable.

Pros & Cons

Pros

• Class-A fire rating gives peace of mind for flammable-exposure areas.
• High coverage per kit and dual nozzles make it efficient for larger jobs.
• Rigid cured foam improves structural stability and blocks air infiltration.
• Included cleaner and reported ease of application add value for regular users.

Cons

• Some customers reported mixed experiences with nozzle quality and installation consistency, so careful setup is needed.
• A few users mentioned adhesion variability on certain substrates, so pre-test in an inconspicuous area.

Specifications

Our Verdict

The 18-pack Spraycoat Fire Rated Spray Foam Kit is a strong value for projects that demand both flame resistance and lasting thermal performance. It suits contractors and serious DIYers who need broad coverage, durable airtight sealing and a controlled application system. While nozzle quality and adhesion should be checked before full deployment, the overall combination of Class-A safety, structural stability and included cleaner makes it a practical choice for medium to large insulating jobs.
