Spray Foam Insulation 360 Sq.Ft. - Closed Cell Polyurethane Foam

In this review the Sprayman Spray Foam Insulation 360 sq.ft. kit is evaluated for DIYers and small contractors who need a compact, high-performance insulation option. The single biggest reason to consider it is its combination of thermal and acoustic protection with a claimed Class-A fire rating and substantial energy savings potential; this makes it appealing for attic and wall patches where boosting R-value and cutting heat transfer matter most.

Key Features

• Class-A Fire Rated: The product carries a Class-A fire rating including ASTM E84, which gives confidence in its fire safety performance for interior roof and wall use.
• Energy Saving: Manufacturer guidance suggests up to 40% to 60% energy savings by reducing heat loss through improved roof and wall insulation.
• Wide Material Compatibility: The foam adheres to many substrates such as drywall, wood, concrete, brick and metal, making it useful for diverse repair and retrofit tasks.
• Ultra Technology Formula: The user-friendly polyurethane formula is designed to limit warping of door and window frames and offers both thermal and sound insulation.
• Temperature Guidance: Best results require cans near 68F and an effective application range from 41F to 86F, which gives practical guidance for planning jobs.

Who It's For

This product is best suited to homeowners doing attic, wall or small roof insulation projects and to handymen who need a portable spray foam solution that claims high fire rating and broad adhesion. It serves well for insulating sheds, campers, RVs and small boats where spot repairs and localized insulation are required.

Professionals with large-scale commercial jobs or anyone needing an application gun and cleaner included should look elsewhere, since the kit does not include a gun or cleaner and the sprayability and adhesion received mixed feedback from customers.

Pros & Cons

Pros

• Class-A fire rating and ASTM E84 compliance provide a safety advantage in interior applications.
• Claims of 40% to 60% energy savings make it attractive for improving thermal performance.
• Adheres to many common building materials and is paintable, simplifying finishing work.

Cons

• Some customers report inconsistent foam quality and sprayability, including instances where the foam behaved like open cell rather than closed cell.
• Gun and cleaner are not included, so additional purchases are required for many users.

Our Verdict

For homeowners and small contractors seeking a portable insulation option with a Class-A rating and broad substrate compatibility, this Spray Foam Insulation kit delivers clear advantages in thermal and acoustic protection and good value when the cans perform as intended. However, those who prioritize guaranteed closed cell performance, flawless sprayability, or need an out-of-box gun should factor in the mixed customer reports before buying.

Frequently Asked Questions

Does this kit include an application gun and cleaner?
No, the cans are supplied without a gun or cleaner, so those must be obtained separately for most spray applications.

Yes, but cans should acclimate to room temperature; optimal results occur at about 68F and the cans perform between 41F and 86F.

Will it stick to common building materials?
Yes, it bonds to drywall, wood, concrete, metal and many other substrates listed, but some users have reported varying adhesion in practice.
