Introduction: What Is Class 0 Foam?
When fire safety meets acoustic performance, Class 0 Foam, also known as Fireseal, rises to the challenge. In today’s demanding industrial, automotive, and commercial sectors, this foam offers a unique blend of fire resistance and sound absorption. Unlike regular foam, Class 0 Foam is treated with a mineral compound to ensure a nil burn rate, making it the ideal solution for high-risk fire environments.
Its chemically inert and non-dusting nature means it is safe and versatile across multiple applications. Whether you’re trying to reduce noise in an engine room or improve safety in public transport, Class 0 Foam delivers. Plus, its flexibility allows it to contour easily to curved or complex surfaces, ensuring a snug fit no matter the installation area.
In this article, we’ll explore the key features, benefits, applications, and industries that rely on Class 0 Foam, as well as why it stands out as a modern solution to acoustic and fire-related challenges.
1. The Science Behind Class 0 Foam
The unique composition of Class 0 Foam sets it apart from conventional insulation and acoustic materials. Here’s a breakdown of its scientific advantages:
- Fire Resistance: Treated with a mineral compound, the foam does not support combustion. In fact, it holds a nil burn rate, making it a prime choice for environments with elevated fire hazards.
- Chemically Inert: This means it does not react with other chemicals, making it suitable for sensitive environments like medical equipment or HVAC systems.
- Non-Dusting and Non-Fibrous: Safer to handle than fiberglass alternatives, especially in confined or air-circulated spaces.
Its availability in different densities also allows engineers and designers to choose the perfect fit for their specific acoustic or fireproofing requirements. For example, high-density Class 0 profile foam is especially praised for its exceptional sound absorption properties.

2. Key Benefits of Class 0 Foam
✅ Versatility of Form
- Available in sheets, roll foam, and profiled foam
- Can be customized with foil facings, self-adhesive backing, or even composite layers like lead foil and polymeric barriers
✅ Exceptional Acoustic Control
- Used in generator canopies, marine vessels, and industrial machinery
- Efficiently absorbs mid- to high-frequency sounds and minimizes echo and reverberation
✅ User-Friendly
- Easy to cut and shape to match curves and complex shapes
- Safe to handle, even in air movement zones, as it doesn’t erode or release particulates
✅ Eco & Health Conscious
- CFC & HCFC free
- Nontoxic, which is crucial in domestic goods and public transport sectors
3. Major Applications of Class 0 Foam
From small studio spaces to massive marine engines, Class 0 Foam finds its place in nearly every industrial niche. Here’s how:
🎙️ Recording & Audio Rooms
- Reduce echo and background noise
- Enhance audio clarity in recording and broadcasting environments
🚚 Automotive and Heavy Vehicles
- Ideal for headliners, cabin trims, and engine soundproofing
- The Silver Dolphin fabric is recommended for aesthetic and functional finish
🚢 Marine & Boat Insulation
- Suitable for high-heat environments
- Often equipped with foil-facing fronts to resist moisture and improve fire retardancy
🏗️ Construction and Machinery Enclosures
- Used in construction vehicles and machinery housings to prevent the spread of noise
- Also helpful in HVAC systems where noise control and fire resistance are both required
🏥 Medical Sector
- Chemically safe for use in sterile environments
- Acoustic properties help reduce operational noise in medical machinery
4. Installation Tips for Maximum Effectiveness
Proper installation ensures that Fireseal performs to its full potential. Consider the following guidelines:
- Surface Preparation: Ensure the application surface is dry, clean, and free of debris.
- Adhesion: Use appropriate adhesives like spray glue or self-adhesive backing.
- Coverage: To effectively reduce noise, cover at least 25–30% of reflective surfaces in the room.
- Placement: Focus on areas with high sound reflection like corners, machinery panels, or around HVAC ducts.
5. Industry Use Cases and Success Stories
✅ Public Transport & Rail
Acoustafoam Ltd supplies customized foam profiles to the public transport sector to improve passenger comfort and reduce cabin noise—all while complying with strict fire safety standards.
✅ Power Generation
