Introduction: Why Class 0 Foam Matters
In industries where safety and performance are non-negotiable, Class 0 Foam stands out as one of the most trusted materials. Engineered with a mineral compound to provide a nil burn rate, it has become the go-to solution for areas with high fire risk. More than just a fire-resistant material, it also functions as an acoustic barrier, reducing unwanted noise in environments such as engine rooms, heavy vehicles, marine applications, and industrial machinery enclosures.
Often referred to alongside Fireseal technology, Class 0 Foam ensures not only fire safety but also a more controlled acoustic environment, making it invaluable across multiple sectors like construction, automotive, and power generation.
Understanding Class 0 Foam and Fireseal
Class 0 Foam is a highly modified flexible open-celled polyurethane foam, specifically treated to resist fire. It doesn’t support combustion, is chemically inert, non-dusting, and remains flexible enough to be shaped for curved or complex surfaces. This makes it versatile for installation in confined or irregular spaces.
In addition, Fireseal acts as an added protection layer, enhancing the foam’s fire-retardant capabilities. When used together, Class 0 Foam and Fireseal provide a dual benefit—fire resistance and sound absorption.
Available in different forms—sheets, rolls, profiled foam, and composite designs—it can also be customized with self-adhesive backing, metallic foil facings, or polymeric barriers to match specific project needs.
Key Benefits of Class 0 Foam
The popularity of Class 0 Foam isn’t accidental—it offers multiple advantages that other conventional foams cannot match.
1. Fire Resistance
The foremost benefit is its fireproof performance. With a nil burn rate, it helps reduce risks in high-temperature or flame-prone environments.
2. Acoustic Performance
The high-density Class 0 Foam delivers excellent sound absorption, reducing reverberations and enhancing clarity in noisy industrial and commercial settings.
3. Flexible & Easy to Install
Its lightweight and flexible structure makes it easy to cut, shape, and fit—even on irregular or curved surfaces.
4. Safe & Sustainable
- Nontoxic
- CFC & HCFC free
- Non-fibrous, meaning it doesn’t release harmful particles into the air.
5. Multiple Finishes
It can be supplied with spray-applied coatings, silver dolphin fabric for automotive interiors, or foil facings for marine and high-heat applications.
Applications Across Different Sectors
Automotive Industry
In vehicles, Class 0 Foam is used for cabin trim panels, headliners, and soundproofing. The Fireseal property adds fire safety, while its sound absorption helps improve passenger comfort.
Marine and Boats
Marine environments demand materials that can resist both fire and noise pollution. Class 0 Foam with foil facings is ideal for engine rooms, control cabins, and bulkheads.
Power Generation
Generator canopies and power plants often generate intense noise and heat. By installing Class 0 Foam, operators benefit from noise reduction while also mitigating fire risks.
Industrial Machinery
Factories and workshops are notoriously loud. Class 0 Foam works effectively in machinery enclosures, helping reduce noise exposure for workers and meeting health and safety regulations.
Construction & HVAC
From office spaces to HVAC ducts, Class 0 Foam is used as both an insulator and Fireseal barrier. It improves energy efficiency while preventing the spread of fire in buildings.
Comparison with Acoustic Foam
While acoustic foam is widely used for soundproofing in studios, offices, and public spaces, it does not provide fire resistance. Class 0 Foam, on the other hand, combines both fireproofing and soundproofing properties.
For projects where safety and sound control are equally important, Class 0 Foam is the superior option compared to regular acoustic foam panels.
How Class 0 Foam is Supplied
Acoustafoam, one of the pioneers in the field, supplies Class 0 Foam in multiple forms:
