Fireseal Class 0 Acoustic Foam Sheets

Fireseal™ is an acoustic foam with a class 0 fire rating; the highest level of fire resistance possible for a flexible acoustic foam. It has passed the following fire safety tests – BS 476 Part 6 & 7 (Class “0”), EN 13501-1 Euro Class B-s1, d0 and UL94 94-V-0.

This foam is non-fibrous and does not shred through contact with high velocity airflow. It received a PASS when tested for Air Erosion Resistance (4001 – 6000 FPM) (ASTM C1071-05 12.7). This means that it can be safely used in airflow systems as it does not dust or migrate.

Fireseal Class 0 Acoustic Foam is also resistant to most fungus and bacteria as it contains anti-fungal agents. When tested for Mildew (Fungus) Resistance (ASTM D-2020-92) it was found to not support growth.

As with all acoustic foam, the acoustic performance of Fireseal improves according to the thickness.

The NRC (Noise Reduction Coefficient) of a 12mm thick random incidence is NRC > 0.27. Meanwhile, a 50mm thick random incidence is NRC > 0.67. This means that a 12mm thick piece can absorb up to 27% of sound wave energy, while a 50mm piece can absorb up to 67%.

Fireseal Class 0 Acoustic Foam Sheets are available in thicknesses ranging from ½” to 2”. Each sheet measures approximately 200 cm x 100 cm (78.7” x 39.3”). Please note that sheet sizes may vary slightly as a result of the manufacturing process (+/- 2 cm tolerance).

Common Applications for Fireseal Class 0 Acoustic Foam

There are many effective applications for Fireseal Class 0 Acoustic Foam. As well as general acoustic treatment in buildings, this advanced foam grade can be used to treat the following areas –

• Automotive – (Cars, Buses, Vans, Tractors, Trains, Trucks, Excavators, etc).
• Watercrafts / Marine Vessels.
• Power Generators.
• Extractor Fans.
• Compressors.
• Ductworks.
• Air Handlers.
• Home Appliances.

Fireseal is often used for acoustically treating a wide variety of buildings and is a popular foam for shop fitting. From cinemas to retail stores and office buildings, it can be used to improve room acoustics whilst maintaining high fire safety standards.

Because it has a class 0 fire rating, this foam can also be used on oil rigs, inside generator rooms to form a fire seal and as a mattress to offer increased protection in prisons and other high hazard environments.
