Acoustic Foam Roll

Class 'O' acoustic polyurethane foam rolls

Acoustic Foam Roll

Advanced Seals and Gaskets Ltd pride themselves on being one of the UK’s largest stockists and suppliers of non-metallic materials including foams, sponges, rubber, plastics and specialist papers.  One such material is Class O acoustic polyurethane foam, used to manufacture acoustic polyurethane foam rolls, which may also be referred to as acoustic foam, impregnated polyurethane or Pyrosorb. 

Class O acoustic foam is converted in-house, where 2-meter x 1.2-meter blocks can be joined and split down into continuous acoustic polyurethane foam rolls at various lengths and thicknesses to order starting from just 1.5mm thick. 

Our state of the art machinery and conversion facilities also allows us to use these acoustic polyurethane foam rolls to cut down into parts such as gaskets, pads and strips allowing us to keep our lead times low, prices competitive whilst producing high-quality products. 

Our on-site laminating and adhesive service also means we can supply acoustic polyurethane foam rolls in a plain finish or laminated with a choice of self-adhesives, foils or even laminated to other materials.

What are Class ‘O’ Acoustic Polyurethane Foam rolls?

Class ‘O’ acoustic polyurethane foam rolls is an open-cell, lightweight foam used for acoustic control, noise and vibration treatment and as thermal insulation material. When used as sound absorption panels or flooring, the material attenuates the sound waves, lowering their amplitude to reduce and control the noise whilst the captured energy from the sound waves is dissipated as heat. 

Class 'O' acoustic polyurethane foam rolls is flame-retardant and meets UL-94 V-0 and  BS476 parts 6 & 7, it is Non-toxic, HCF & CFC Free doesn’t support fungal growth, is dust-free making it ideal for marine, building and construction, automotive, heating & Ventilation and manufacturing.

Class O acoustic foam can be manufactured and supplied as continuous lengths of material (a acoustic polyurethane foam roll), usually at 10 meters long as standard, however, these can be made longer or shorter depending on the material thickness. 

We can use acoustic polyurethane foam rolls to cut smaller parts such as gaskets, strips, pads and washers, or supply them as full rolls for customers to cut down use as and when parts are required.

    Why use Class ‘O’ Acoustic Polyurethane Foam Rolls?

    Many customers use class 'O' acoustic polyurethane foam as a solution to sound, vibration and thermal insulating applications. Acoustic polyurethane foam rolls and products can be found used in most industries including engineering, construction, automotive and HVAC to name a few. Class 'O' acoustic foam rolls can be used for sound reduction by controlling the reverberation that sound makes when bouncing off the walls and flooring. 

    As well as the sound-absorbing properties, acoustic foam is used in many other applications as the material has high performance in fire protection and thermal insulation. This makes acoustic foam great for use in the construction and automotive industries where strict regulations apply. 

    The durable nature of acoustic foam allows us to cut the acoustic polyurethane foam rolls down into other usable parts using our specialised in house equipment to your specifications. Class 'O' acoustic foam rolls can be manufactured in thicknesses of around 1.5 mm, and supplied plain or with a range of coverings such as foil, self-adhesive or even laminated to other sponge and rubber materials in order to increase the number of uses and properties the rolls have.

    The Advantages of using Class ‘O’ Acoustic Polyurethane foam rolls

    Using Class ‘O acoustic polyurethane foam rolls offer a huge number of benefits and uses, with blocks of material kept in stock ready for conversion. Not only do these rolls of material help with soundproofing, but they also act as sound and vibration absorption panels and can help sound transmission loss. 

    These rolls of material and products cut from them can be used to create soundproof enclosures in which noisy machinery and equipment can be housed and also as linings within automotive and HVAC applications.  

    As the class ‘O’ foam is flame retardant, it is often one of the safest materials to use within building and construction for soundproofing underlay under flooring, combined with plasterboard on walls and ceilings, especially studios or home cinema rooms and even within engine rooms such as on marine vessels.

    Benefits of using Class ‘O’ Acoustic Polyurethane Foam

    • Can be used as floor, wall or ceiling linings for soundproofing
    • Reduce unwanted vibration
    • Flame retardant
    • Can be supplied as an acoustic foam or laminated to foils, barrier sheets or adhesives
    • Sheets can be cut down into smaller parts such as pads, strips or even gaskets
    • Available in various thicknesses and weights
    • Doesn’t support mildew or fungal growth

    Different Types of Acoustic

    We at ASG supply a variety of materials with acoustic properties, with Class O acoustic foam being the most popular where a combination of soundproofing and flame retardancy is required.  It is a lightweight and flexible material excellent for use as pipe lagging, duct lining and engine room/automotive insulation and much more.  Class O acoustic foam is available in various forms including:
