Foil Faced Acoustic Foam Seals

Advanced Seals & Gaskets Ltd pride themselves on being one of the UK’s largest suppliers of non-metallic sealing products, including those manufactured using foams, sponges, rubber, plastics, corks and specialist papers, taking the form of gaskets, washers, O-rings and strips, which are all designed for the purpose of preventing leaks or the ingress of air, fluids, dust, dirt and gas. 

One such material is foil-faced acoustic polyurethane foam. Class O acoustic foam is manufactured and stocked in block form, where it can be converted into products at various thicknesses starting from just 1.5mm thick and laminated with the foil layer. Our state of the art machinery and conversion facilities also allows us to also produce sheets and cut parts such as gaskets, washers and other seals which are all made to order and are manufactured using samples or drawings provided by customers. 

As each form of seal needs to be manufactured using a different process, ASG has invested heavily in various machinery meaning we can supply seals in high and low volumes, 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 seals in a plain finish, laminated on the reverse face with a choice of self-adhesives or even laminated to other materials.

What are Foil Faced Polyurethane Foam Seals?

Foil-faced polyurethane foam is a combination of Class ‘O’ acoustic foam is an open-cell, lightweight foam covered in layers of aluminium foil, 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. 

Foil-faced acoustic foam is flame-retardant and meets UL-94 V-0 and  BS476 part 6 & 7, it is Non-toxic, HCF & CFC Free doesn’t support fungal growth, is dust-free making it an ideal material for gasket production for use in marine, building and construction, automotive, heating & Ventilation and manufacturing applications. 

Foil-faced polyurethane foam seals are one of many products often taking the form of cut gaskets, strips, washers or extruded profiles, used to join surfaces together, acting as a separator or a barrier to prevent liquids, particles or gases from escaping or penetrating the application. 

Most of the seals produced by advanced seals and gaskets can be supplied with a choice of self-adhesives which assists with the placement of the seal and holding it in position.

    Why use Foil Faced Polyurethane Foam Seals?

    Many customers use class foil faced polyurethane foam and products manufactured from this material as a solution to sound, vibration and thermal insulating applications. Acoustic foam materials and products can be found used in most industries including engineering, construction, automotive and HVAC to name a few.

    Class O acoustic foam is primarily used for sound reduction and in many other applications as the material has high performance in fire protection and thermal insulation.  The addition of the foil facing adds additional thermal and insulation properties, as the aluminium foil reflects and isolates heat, whilst offering extra shielding against vibration and noise. Foil-faced PU foam seals are designed to prevent the escape or ingress of dust, air,  gases and in this case flames when compressed between irregular surfaces - very much used in the same way as a gasket.

    Seals can also be used as an aid for shock, noise and vibration dampening in a range of industries, 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 and shape the material using our specialised in house equipment to your specifications.  

    Foil-faced PU foam seals can be made in thicknesses of just a few mm, and supplied plain, laminated with foil on both faces, covered with self-adhesive on the reverse face or even laminated to other sponge and rubber materials in order to increase the number of uses and properties the seals have. 

    Advantages of Using Foil Faced Polyurethane Foam Seals

    Using foil-faced polyurethane foam seals offers a huge number of benefits and uses.  Not only do they offer additional soundproofing, but they also provide vibration absorption and can help sound transmission loss. 

    These seals can be used as components within soundproof enclosures in which noisy machinery and equipment are housed and also in many automotive and HVAC applications.  

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

    The foil offers resistance to moisture and oils, which is also easy to clean, it is lightweight, easy to apply foam odour free and can be recycled.

    Benefits of Using Foil Faced Polyurethane Foam

    • Can be used as floor, wall or ceiling linings for soundproofing enclosures and rooms
    • Reduces unwanted vibration, noise
    • Flame retardant
    • Can be supplied as foil faced on both sides or with a self-adhesive backing on the other face
    • Available in various thicknesses and weights
    • Doesn’t support mildew or fungal growth

    Different Grades

    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:

    • Class O acoustic foam sheet
    • Convoluted egg box foam
    • Class O acoustic with barrier foam
