Here at ASG we convert and supply a large array of non-metallic sheet materials including Polyurethane foam, in a number of grades, one of which includes acoustic convoluted egg box polyurethane foam sheets, also sometimes called egg box foam or egg crate foam. Egg box foam is usually manufactured in block form and then split to thickness as acoustic egg box foam sheets using a specialist splitter which produces the sheets with a convoluted surface consisting of peaks and troughs.
These acoustic egg box foam sheets are available in several different thicknesses (measured from base to tip of the peak) and are usually supplied in pairs that interlock, especially when they’re being used for packaging purposes. Acoustic egg box foam sheets are usually available in thicknesses from 25mm to 50mm thick and in a standard sheet size of 2 meters by 1.2 meters but can be made to order at bespoke sizes.
Acoustic eggbox foam can be supplied to customers as full sheets or we can convert the acoustic egg box foam sheets into other usable products including pads and gaskets using one of our many presses, bandsaws or CNC machines. Egg box foam sheets can be supplied in a range of finishes using our in-house adhesive and laminating facilities, where they can also be laminated to other materials to produce composite sheets, or covered with one of our many foils or self-adhesives.
What are Acoustic Egg Box Foam Sheets?
Acoustic convoluted egg box polyurethane foam is an open-cell polyurethane product, manufactured to create a surface consisting of continuous peaks and troughs and containing flame retardant additives which creates a class ‘O’ non-flammable material with excellent sound-absorbing properties.
Acoustic egg box foam sheets are split directly from jumbo blocks and are specially designed for sound absorption whereby the convoluted finish creates an increased surface area and therefore reduces echo and reverberation inside enclosures and studios.
Our acoustic egg box foam sheets can be converted into a range of other products, or supplied in full allowing customers to cut their own parts as and when required.

Why use Acoustic Egg Box Foam Sheets?
Acoustic egg box foam sheets, also sometimes called convoluted acoustic foam sheets or eggbox foam are a very popular product used for both packaging, usually in the form of case inserts, and for sound control in rooms such as cinemas, music studios or machinery enclosures.
Egg box foam is a very soft material that can be easily cut and will hold adhesives well so that they can be used to adhere to walls and ceilings, it also offers class ‘O’ flammability performance meaning it is safe to use within buildings and automotive applications.
Advantages of Using Acoustic Egg Box Foam Sheets
Acoustic egg box foam sheets offer a number of benefits and uses, they’re manufactured using a material that is open cell, soft, and flexible made with flame retardant additives, meaning it complies with UL94 HF1 standards.
Acoustic egg box PU foam sheets offer excellent sound-absorbing qualities as the textured surface profile creates a larger surface area, which disperses waves more efficiently than the flat-surfaced variant.
Our egg box foams can also be used as packaging or case inserts for securely transporting irregular shaped or delicate items which are securely sandwiched between 2 interlocking layers of the convoluted foam, offering to cushion, abrasion resistance and impact protection.
Applications that utilise acoustic convoluted egg box polyurethane foam sheets include HVAC systems, enclosures for machinery, compressors or generators, acoustic panels for sound insulation and within automotive and marine. Acoustic convoluted egg box foam is easy to cut using scissors, knives or press tools.
Benefits of using Acoustic Egg Box Foam
- Non-toxic, HCF & CFC and Dust Free
- Acoustic egg box foam sheets sheets are Suitable for packaging and acoustic applications
- Durable and easy to cut
- Acoustic egg box foam sheets are shock and abrasive resistant
- Doesn’t support mildew or fungal growth
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
- Foil-faced class O acoustic foam
- Class O acoustic with barrier foam
