Pyrosorb-S is a class "0" accredited cellular acoustic foam.
Class 0 is the best Building Regulations designation for materials that protect from the spread of flames and limits the amount of heat released from the surface during a fire.
With its flexibility and non-irritant characteristics class 0 foam is a safe and easy to install product.
Its durability has been proved on many prestigious projects throughout the world.
Class 0 foam can be cut and shaped easily and safely. It will readily accept facings,
acoustic barrier layers and self adhesive backing for ease of fixing. Class 0 Acoustic foam is available in sheets, tiles or cut to size.
UK's largest Pyrosorb-S acoustic foam supplier
Pyrosorb-S Class 0 accredited foam is a superior grade of foam in its class, manufactured in the UK and distributed worldwide by Efoam.
Class 0 is a fire resistant, flexible, open celled polyurethane foam.
Being open celled with a high density it is an excellent sound absorption material.
Is a safe alternative to conventionally used products.
Easy and safe to handle (reduced labour costs).
Does not erode or migrate in air movement (up to 6,000 ft/min, 2,800Mt/min).
Is non-fibrous eliminating the potential health hazards associated with fibrous products.
Class 0 foam may be used in almost any absorption or containment of noise application, including:
Air-conditioning equipment and duct systems
Acoustic wall panelling and enclosures
Generator rooms and forming a fire seal
Engine bay compartments
Automotive and Marine applications
Due to the popularity and high demand of the Pyrosorb-S material, Efoam have invested in a larger warehouse facility to ensure that we maintain high stock levels at all times.
We have supplied the Pyrosorb-S foam in vast quantities to international customers in Dubai (UAE), Sultanate of Brunei, Sultanate of Oman, Malaysia and many other international destinations. Efoam are proud to have worked with some of the world's most distinguished architects, specifiers and construction companies.
Over the last ten years, the feedback we have received from our customers when sending samples of the Pyrosorb-S compared with a leading UK competitor's material, the overwhelming preference on the part of our customers has been towards the Pyrosorb-S material.
Although both products are class 0 accredited, the feedback we have received leads us to have a firm belief that the astounding preference towards the Pyrosorb-S is due to the superior, rich aesthetic and high quality nature of this product in comparison to other class 0 materials that are available in the UK.
We currently ship to the Republic of Ireland on a 2-3 day delivery service. However, Efoam will shortly be completing on a commercial distribution contract in collaboration with a leading logistics company in the Republic of Ireland. This will allow Efoam to offer a next day service on the Pyrosorb-S material.
Efoam are also in the process of negotiating on a purchase of a central distribution facility in the EU, allowing us to deliver on a next day service to mainland Europe. Our commercial partners are looking into the feasibility of manufacturing this product in the EU due to the economic uncertainty that the Brexit has posed.
United Nations and other NGO's Procurement departments needing further clarity to class 0 foam mattress or other foam requirements can contact our dedicated NGO support team by email.
Efoam also produce bespoke die-cut foam components using the Pyrosorb-S material for use as a fire seal in air conditioning, ducting systems and electrical cabinets. Efoam are more than happy to discuss any requirements that you may have, whether it is for UK market or international markets.

Is Pyrosorb-S open or closed celled foam? - Pyrosorb-S 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
Where can Pyrosorb-S be used? - Pyrosorb-S can be used in almost all acoustic applications.
What adhesives should be used? - There are three types of adhesive that are fully compatible with Pyrosorb-S. 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 Pyrosorb-S complete with a self-adhesive backing.
How long will Pyrosorb-S remain serviceable? - Providing Pyrosorb-S 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.
