Sprayman Spray Foam Insulation Kit (120 Sq.Ft.) - Closed Cell Foam

In this review of the Sprayman Spray Foam Insulation Kit the bottom line is simple: this kit is aimed at homeowners and DIYers who need a robust, long-lasting closed cell polyurethane foam for small to medium sealing and insulation jobs. The single biggest reason to buy is the combination of a Class-A fire rating and strong thermal performance that can reduce energy loss, making it appealing for attic, wall and gap sealing where durability and safety matter. The review notes the kit comes with a dispensing gun and cleaner for convenience and requires following temperature guidance for best results.

Key Features

• Class-A Fire Rated: Provides a trusted safety profile with ASTM E84 compliance so treated areas meet a recognized flame-spread standard.
• Energy Saving: Closed cell polyurethane helps reduce heat transfer and can contribute to significant energy savings when used to insulate roofs and walls.
• Durable Seal: Creates a long-lasting bond that reduces the need for frequent rework on roof and wall insulation once applied correctly.
• Simple Bonding: Adheres well to common building materials and is paintable, making it straightforward to finish after application.
• Accessory Included: The kit ships with a gun and cleaner so users have the basic tools needed to apply and clean up.
• Wide Application Range: Can be used on many surfaces such as drywall, wood, concrete, metal and composite panels for thermal and acoustic improvements.

Who It's For

The kit is best for homeowners, contractors doing small sections, and DIYers who need a compact solution for sealing gaps, insulating attic spaces or spot-treating walls. Its Class-A fire rating and closed cell chemistry make it suitable where durable thermal and acoustic protection is desired.

It is less suited for very large commercial projects where bulk or specialized equipment is required, or for users who need guaranteed uniform coverage across wide areas; some customers reported variability in can performance, so those needing strict consistency may prefer pro-grade, bulk systems.

Pros & Cons

Pros

• Class-A fire rating and ASTM E84 compliance provides added safety for building applications.
• Strong insulating performance that helps cut energy loss when applied correctly.
• Good adhesion to a wide range of building materials and the ability to be painted after cure.
• Includes a gun and cleaner, simplifying setup and cleanup for DIY use.

Cons

• Coverage per kit is modest and value perceptions vary among users depending on application size.
• Some customers reported inconsistent sprayability or bad cans, so occasional product variability is a realistic limitation.
