Foil Acoustic Foam Sheet

Advanced Seals & Gaskets Ltd pride itself on being one of the UK’s largest converters, stockists and suppliers of non-metallic materials including foams, sponges, rubber, plastics and specialist papers.  One such material is foil-faced acoustic polyurethane foam. 

Foil-faced acoustic foam sheets are converted in-house, were 2 meters long by 1.2 meters wide polyurethane foam master blocks are split down into various thicknesses, made to order starting from just 1.5mm thick and then laminated with a foil covering. 

Our on-site state of the art machinery and conversion facilities also allows us to cut down these sheets into smaller sized or parts such as gaskets, pads and strips allowing us to keep our lead times low, prices competitive, whilst producing high-quality products. 

Our laminating and adhesive service also means we can supply foiled faced acoustic polyurethane foam rolls with foil applied to both faces, with a choice of self-adhesives or laminated to other materials.

What are Foil Faced Polyurethane Foam Sheets?

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, these sheets attenuate 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 foam 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.

During the conversion process, the acoustic foam material is laminated with aluminium foil which is also non-flammable and wear-resistant.  Foil-faced acoustic foam can be manufactured and supplied as continuous lengths of material (a roll), usually at 10 meters long as standard, for customers to cut into sheet sizes of their choice or as pre-cut sheets.

    Why use Foil Faced Polyurethane Foam Sheets?

    Many customers use class O acoustic foam 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 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. 

    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.  The foil material is resistant to wear and tear and is often found used in plant machinery, hydraulic power pack enclosures, internal engine compartments and compressor housings.  

    Foil-faced acoustic foam sheets can be manufactured in thicknesses of around 1.5 mm, and supplied with the foil on one or both faces, with foil on one face and self-adhesive on the other or laminated to other materials to create composites.

    Advantages of Using Foil Faced Polyurethane Foam

    Using foil-faced polyurethane foam offers a huge number of benefits and uses, with blocks of material and various roll thicknesses kept in stock ready for conversion.  Not only can these sheets of material offer additional soundproofing, but they also act as sound and vibration absorption panels and can help sound transmission loss.

    These sheets 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 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 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. 

    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 also be supplied as foil-faced barrier sheets or with a self-adhesive backing on the other face
    • 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 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
    • Class O acoustic foam with foil on both faces
