CC400 Class ‘0’ Acoustic Foam

CC400 Class ‘0’ Acoustic Foam

CC400 Class ‘0’ Acoustic Foam is manufactured by impregnating standard foam with liquid minerals resulting in a fire-resistant acoustic foam which is able to withstand various ignition sources. With its flexibility and non-irritant characteristics, it is a safe and easy to install product it can be cut and shaped easily and safely. It will readily accept facings, acoustic barrier layers and self-adhesive backing for ease of fixing. We recommend Class ‘0’ for multiple s/noise absorption applications including, Air-conditioning equipment and duct system/acoustic wall panelling and enclosures/ generator rooms/engine bay compartments/automotive/marine applications/M.O.D. vehicles. 

Do not confuse this product with standard fire retardant foam, Class ‘0’ is fire-resistant not fire retardant, with the difference being Fire retardant foam will burn until the ignition source is removed, whereas Class ‘0’ will not burn.

High-Density Open Cell Class ‘0’ foam


To obtain a Class “0” certificate some companies supply test samples at the higher end of their density specification range knowing a lower density product would fail. Based on many years of experience we know we need the density to be 90kg/m3 or more to ensure a fully fire-resistant foam.

We would suggest all impregnated PU foams are weighed to ensure they are at least the same density or greater than the product test certificate states.

High-Density Open Cell Class ‘0’ foam has exceptional acoustic properties and is an excellent sound absorption material, it is a safer alternative to conventionally used products, it is easy and safe to handle, it does not erode or migrate in air movement and is non-fibrous eliminating the potential health hazards associated with fibrous products.  Independent acoustic tests confirm noise reduction performance is greater when the thickness of the product is increased.

CC400 Foam is a flexible open cell acoustic foam that includes anti-bacterial & fungal additives, passing both BS476 Part 6 & Part 7 achieving Class “0” and tested to ASTM C1071-05 (Air Erosion Test) making CC400 “The safest solution”.

The BS476 fire test has to be carried out at a registered test facility, Warrington Exova. The fire test is made using a number of samples which have to be conditioned for a number of days to ensure they are as they would be supplied. All the samples have to pass.  The actual fire test measures only the surface spread of flame, it is possible to apply foil or a fire-rated facing to the tested face of material to get a Class “0”. CC400 is tested plain and has also been tested to the European test standard EN13501-1 achieving a B-s1,d0. CC400 is also tested for other applications, by cutting through the surface and attempting to burn the inside of the foam, again passing the test well.


 Do not accept foam tested at 90kg+ density but supplied at 85kg or less as it is a potential fire risk.
