Class 0 Acoustic Foam Sheets

Buy Class 0 acoustic foam sheets for specification-led acoustic treatment. These fire-rated acoustic foam sheets are available as a flat sheet in four thicknesses or a 35mm convoluted Class 0 foam sheet, with adhesive and unbacked options available. Both products use the All Foam Class 0 technical data sheet, which states BS 476 Parts 6 and 7 fire performance.

Choose the Class 0 Acoustic Foam Format

The Class 0 foam sheets on this page are intended for suitable acoustic treatment applications, but they differ in surface profile, thickness choice and backing arrangement. Select by the actual project specification rather than appearance alone.

Flat Class 0 acoustic foam 6mm, 12mm, 25mm or 50mm Two sheet sizes with or without self-adhesive backing. Convoluted Class 0 acoustic foam 35mm egg-crate profile Two sheet sizes with optional self-adhesive backing. Check the specification BS 476 Parts 6 and 7 Review the All Foam technical data sheet before specification-led or critical installations.
Class 0 acoustic foam is acoustic treatment, not a complete soundproofing system. It can help control reflected sound and enclosure noise, but stopping sound transmission normally requires a wider construction using appropriate mass, isolation and sealing.

Flat and Convoluted Class 0 Foam

Quick answer

Understand the material

What Is Class 0 Acoustic Foam?

All Foam Class 0 acoustic foam is an open-cell acoustic and thermal polyurethane material manufactured with impregnated fire-retardant compounds. Its technical data sheet states UK Building Regulations Class 0 to BS 476 Parts 6 and 7.

Customers also sometimes search for Class O acoustic foam using the letter O. The classification stated on the All Foam technical data sheet is Class 0 with the number zero, so always check the exact project specification and technical document before ordering.

Acoustic treatment

The open-cell structure allows sound energy to enter the foam rather than reflecting entirely from the surface. This makes the material relevant to suitable acoustic treatment and enclosure applications.

Fire performance

The current All Foam technical data sheet states Class 0 to BS 476 Parts 6 and 7, Class 1 surface spread of flame to BS 476 Part 7, and UL94 V-0 and 94-5V.

Specification-led use

Class 0 should not be treated as a generic quality label. Where a project names a fire standard, compare the exact requirement with the supplied data sheet and confirm suitability for the finished installation.

Where Class 0 foam is used

Class 0 Acoustic Foam Applications

The All Foam technical data sheet identifies commercial and public-building acoustic treatment and metal-enclosure vibration dampening among the relevant uses. The correct choice still depends on the complete project specification.

Commercial and public spaces

Cinemas, theatres, hotel lounges, restaurants, cafés, schools, lecture spaces and other premises where the stated Class 0 acoustic material is appropriate to the project specification.

Studios and listening spaces

Suitable acoustic treatment can help control reflections and reverberation inside recording, rehearsal, media and listening spaces. Check whether the project requires the Class 0 grade rather than standard acoustic foam.

Machinery and metal enclosures

The technical data sheet notes vibration dampening within metal enclosures. Check temperature, fixing method, airflow, fire specification and any additional industrial requirements before installation.

Specification-led acoustic projects

Where a contractor, venue or client provides a named fire standard, use that wording to check the data sheet. Contact All Foam when the requirement or finished assembly needs technical confirmation.

Backing and installation

Self-Adhesive Class 0 Acoustic Foam

Both the flat and convoluted Class 0 sheets can be ordered with or without self-adhesive backing, allowing the fixing method to be matched to the installation. The live product price updates when the backing option is changed.

1. Check the substrate

The receiving surface should be suitable for the selected fixing method. Check cleanliness, stability, finish and whether adhesive could affect the surface.

2. Plan the sheet layout

Measure the treatment area before removing any backing liner. Plan joints, edges, access panels and obstructions so sheets do not have to be repositioned after bonding.

3. Confirm the environment

For machinery, public buildings, heat exposure or other critical applications, confirm that the complete product specification and installation method suit the environment.

4. Keep the data sheet

Where a project is specification-led, retain the technical document with the product grade, thickness, installation location and purchase information.

Acoustic treatment explained

Acoustic Treatment vs Soundproofing

Customers often search for fire-rated soundproofing foam, but acoustic absorption and structural sound isolation are different jobs. Class 0 acoustic foam is primarily an absorptive treatment material.

Use Class 0 acoustic foam to treat suitable reflections, reverberation and enclosure noise. If the goal is to stop noise travelling through walls, floors, ceilings, doors or openings, the project normally needs a broader sound-isolation design. Do not rely on acoustic foam alone as a complete noise barrier.

Helpful answers

Class 0 Acoustic Foam FAQs

Clear answers about Class 0 fire information, sheet sizes, backing, acoustic treatment and specification-led use.

Ask the All Foam Team
What is Class 0 acoustic foam?

The All Foam Class 0 data sheet describes an open-cell acoustic and thermal polyurethane foam manufactured with impregnated fire-retardant compounds. The sheet states UK Building Regulations Class 0 to BS 476 Parts 6 and 7 and Class 1 surface spread of flame to BS 476 Part 7.

Is Class 0 foam the same as ordinary fire-retardant acoustic foam?

No. Fire-retardant is a broader description. The Class 0 products on this page have a separate technical data sheet with stated Class 0 test information. Check the exact grade and supporting document when a project specifies a fire classification.

Is Class O acoustic foam the same as Class 0 acoustic foam?

Class O acoustic foam is a common search spelling that uses the letter O. The classification stated on the All Foam technical data sheet is Class 0 with the number zero. When a project specifies a fire standard, check the exact wording and supporting technical data rather than relying on the spelling used in a search.

Does Class 0 acoustic foam soundproof a room?

Class 0 acoustic foam is used for acoustic treatment and can help control reflected sound, reverberation and enclosure noise. It is not a complete structural soundproofing barrier on its own. Reducing sound transmission through walls, floors, ceilings, doors or gaps normally requires a wider construction approach.

What sizes and thicknesses are available?

The flat Class 0 sheet is available in 100cm × 100cm and 200cm × 100cm sizes at 6mm, 12mm, 25mm and 50mm thicknesses. The convoluted Class 0 sheet is available in the same two sheet sizes at a fixed 35mm thickness.

Does Class 0 acoustic foam have self-adhesive backing?

Both Class 0 products can be ordered with or without self-adhesive backing. Select the backing option that suits the installation and the live product price will update automatically.

Should I choose flat or convoluted Class 0 acoustic foam?

Choose the flat sheet when you need an even surface and a choice of 6mm, 12mm, 25mm or 50mm thickness. Choose the convoluted sheet when a 35mm egg-crate profile suits the installation. Do not assume one profile automatically provides better acoustic performance without project-specific test information.

Can Class 0 acoustic foam be used in machinery or metal enclosures?

The All Foam technical data sheet identifies acoustic treatment and vibration dampening within metal enclosures as relevant uses. Confirm the operating temperature, fire requirement, fixing method and complete enclosure specification before ordering for critical industrial applications.

Where can I check the Class 0 technical specification?

Use the Class 0 Acoustic Foam data sheet linked from both product cards. It lists the stated fire performance, density, hardness, tensile strength, elongation, thermal conductivity, erosion resistance and working temperature range.

Can All Foam help with non-standard Class 0 foam requirements?

Yes. The online selectors show the standard sheet sizes and purchasable options. For non-standard dimensions, specialist conversion or specification-led applications, contact All Foam with the required dimensions, use and technical requirement before ordering.
