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

In this review the Spray Foam Insulation 360 Sq. Ft. kit is evaluated as a ready-to-use option for homeowners and contractors who need fast thermal and acoustic sealing for walls and attics. The biggest reason to consider it is the claimed combination of a Class-A fire rating and strong energy-saving potential, which promises up to 40% to 60% lower heating and cooling costs when applied correctly. The kit ships with a gun and cleaner and targets jobs where a compact, canned polyurethane solution is more practical than rented spray rigs.

Key Features

• Class-A fire rated: The foam is reported to meet ASTM E84 standards, giving buyers assurance about surface flame spread and smoke development compared with untreated cavities.
• Energy saving: The product is intended to deliver significant insulation performance, helping reduce heating and cooling costs by creating an air seal in roofs and walls.
• Durable insulation: Once cured, the polyurethane is designed to be long lasting so users can expect reduced need for repeat roof or wall insulation work.
• Simple bonding: The foam adheres to a wide range of common building materials and can be painted over, allowing for straightforward finishing after application.
• Application flexibility: Two nozzle options support vertical wedge spraying and ceiling work, while the included gun and cleaner simplify on-site use.
• Wide surface compatibility: The formula is described as usable on drywall, wood, concrete, metal, PVC and many other substrates for both thermal and acoustic improvement.

Who It's For

The kit suits DIY homeowners, small contractors and renovators who need a compact, portable spray foam solution for moderate coverage areas such as attic rim joists, wall cavities and around penetrations. Its bundled gun and cleaner make it practical for one-off projects without renting larger equipment.

It is not the best choice for large commercial insulation projects that require continuous spray rigs, nor for users who cannot ensure recommended application temperatures; buyers should also be prepared to check sprayability and adhesion in a small test area before committing to large runs.

Pros & Cons

Pros

• Class-A fire rating gives a safety advantage for interior insulation work.
• Claims of 40% to 60% energy savings when installed as an effective air barrier.
• Included gun and cleaner and two nozzles make the kit ready for varied small jobs.
• Paintable and bonds to many common building materials for easy finishing.

Cons

• Some users report inconsistent foam quality and sprayability, so performance can vary by can and conditions.
• Adhesion and strength have been questioned by purchasers on certain substrates, so pretesting is advisable.

Specifications

Our Verdict

The Spray Foam Insulation 360 Sq. Ft. kit is a practical value option for homeowners and small contractors who need a portable insulating sealant with a Class-A rating and broad material compatibility. It offers strong potential energy savings and comes ready to use, but buyers should test for sprayability and adhesion on their specific substrate before larger runs; when it performs as intended it represents a cost effective way to improve thermal and acoustic performance.

Frequently Asked Questions

Is this truly closed cell foam?
It is marketed as closed cell polyurethane, but some customers have reported open cell-like characteristics, so test a can to confirm the cured foam meets your expectations.

What temperature should the cans be at?
For best results the can should be about 68F; application is effective between 41F and 86F and colder cans should acclimate to room temperature before use.

Will it stick to metal and concrete?
The formula is designed to bond to many materials including metal and concrete, but adhesion can vary by surface condition so cleaning and a small adhesion test are recommended.
