Class 0 Frequently Asked Questions

Fireseal Pyrosorb foam example
  • Is Class 0 open or closed celled foam? - It is an open celled foam. Open celled foams provide access for sound to penetrate the surface enabling sound absorption to take place.
  • What is Class "1"? Class 1 Spread of Flame. A surface Spread of Flame classification of Class 1-4 is achieved using the BS 476: part 7 method for the classification of the surface spread of flame of products. The test is a means of classifying the rate and speed of the spread of flame of a given product. The product is classed on a rating of 1-4, 1 being the best result.
  • What is Class "0"? Class 0 Fire Propagation. The Class 0 test requires the product to have already had a Class 1 spread of flame classification. This test, using the principles of BS 476: part 6: 1989, examines the contribution that the product would give to the growth of a fire. If the product achieves a Class 0 classification then its fire propagation rating is seen to be acceptable according to appropriate specifications.
  • Where can Class 0 be used? - It can be used in almost all acoustic applications.
  • What adhesives should be used? - There are three types of adhesive that are fully compatible with Class 0 foam. These are Neoprene, Acrylic and Polyurethane. Never use a synthetic butyl rubber based adhesive as this may plasticise and lose adhesion over a short period. You may wish to purchase Class 0 complete with a self-adhesive backing.
  • How long will Class 0 remain serviceable? - Providing Class 0 is used in applications where it is not subjected to continuous excessive heat (above 100 degrees Celsius), UV light or water there is no evidence to suggest a serviceable period of less than ten years.
