Kraken Bond Fastcoat Fire Rated Spray Foam Insulation 48 Pack - Fire

In this review the Kraken Bond Fastcoat Fire Rated Spray Foam Insulation is examined for DIYers and contractors who need a high-efficiency, fire-rated closed-cell foam solution. The biggest reason to consider it is the combination of a Class-A fire rating and a strong thermal performance, which makes it suitable for attic, wall and crawl space work where both safety and insulation value matter. The kit ships as a complete set designed for immediate application, so buyers who want a ready-to-use spray foam solution will appreciate its convenience.

Key Features

• Class-A fire rating: Meets stringent fire safety standards including ASTM E84, providing added peace of mind for interior applications.
• High thermal performance: Closed-cell polyurethane foam delivers an R-value of 5.66 per inch for effective heat resistance in conditioned and unconditioned spaces.
• Complete kit: The package includes multiple cans, an ergonomic application gun and cleaner plus basic PPE so work can start without sourcing extra parts.
• Versatile adhesion: Adheres to most common building materials to create an airtight, watertight seal that helps block drafts and pests.
• Temperature guidance: Designed to perform best when the can is at about 68F and remains usable between 41F and 86F, allowing flexibility across seasons.
• Dense monolithic fill: Closed-cell chemistry reduces thermal bridges and limits dew point issues when applied properly and with ventilation.

Who It's For

This product suits homeowners tackling attic or crawl space insulation, small contractors who need a ready-to-use spray foam option, and studio builders seeking improved acoustic isolation because of the foam's acoustic damping qualities. The included gun and cleaner make it practical for single-day jobs where set-up speed matters.

Those who need very large commercial volumes or prefer single-tank professional reactors should look elsewhere, as this kit is packaged as multiple handheld cans for moderate coverage and convenience rather than continuous industrial application.

Pros & Cons

Pros

• Class-A fire rating provides enhanced safety compared with many consumer foams.
• High R-value per inch improves thermal performance in confined cavities.
• Complete kit format (cans, gun, cleaner, PPE) reduces prep time and extra purchases.
• Works across a practical temperature range for most DIY conditions.

Cons

• Coverage reports are mixed; some users find adhesion and board-foot yield vary, so expect differences by surface and technique.
• Not a substitute for large-scale professional spray rigs when very high continuous volumes are required.

For moderate-sized jobs where convenience and safety matter, this kit is a sensible buy.

Frequently Asked Questions

Is the kit ready to use out of the box?
Yes. The package includes cans, an ergonomic gun, cleaner and basic PPE so users can begin work immediately after following the temperature guidance.

What temperatures are best for application?
For peak performance bring cans to about 68F; the product is usable between 41F and 86F but colder cans should be acclimated first.

Does it provide good acoustic insulation?
Yes. The closed-cell foam offers acoustic damping in addition to thermal insulation, making it useful in studio and room isolation situations.
