Product Description

NeoFill acoustic foam is used as an acoustic infill layer for resonance reduction for in-frame insulation, stretched fabric applications, and making DIY acoustic panels. Our acoustic foam is manufactured to high standards, provides a high volume weight, is porously foamed, and is thus optimized for acoustic insulations. Additionally, all of our foams come with a flame protection and provide therewith a plus of safety.

What are the benefits of NeoFill foam?

As you can see on our website, we offer various types of acoustic foams. NeoFill is a high-quality PU foam that is manufactured with a particularly high density of 48 kg/m3, has the smallest pores and an optimised pores per inch ratio. The high density is conducive to a long service life (normally 15-20 years); the small micro-porosity ensures improved absorption, because sound waves are caught and absorbed better and more intensively in foam; and we have optimised the base/profile ratio by means of reverberation chamber measurements so that you can realise the best possible sound in the room. All in all, this sound absorber represents a premium product.

The panels have a very uniform and even colour, and the thickness is accurate upto 0.05mm. The foams also feature a flame-retardant finish to further increase safety. It is sensible to use a foam that is at least flame-retardant, especially in the vicinity of electrical appliances, sockets, etc. The price is slightly higher than local foams, for example, but the quality and the absorption levels are outstanding. If you are planning a more professional application, or want to mount the foam for a longer period (for longer projects) and have very high expectations regarding the acoustic development in the room, you should choose our NeoFill series.

All NanKarrow acoustic foam products have been specially engineered to:

  • Maximize acoustical performance
  • Maximize longevity
  • Maximize flame retardancy
  • Maximize aesthetics

Non-Nankarrow ”poly-” foams (can be polyesters, polyethers, polyurethanes, etc.) usually:

  • Have inferior acoustical performance
  • ”Crumble” or otherwise deteriorate over time
  • Are much more flammable
  • Aren’t as aesthetically pleasing

Acoustical Performance

The acoustical characteristics of foams are dependent on many factors. The more important of these are density and surface area. Nankarrow research engineers strive to maximize these two factors in all our products to achieve the highest possible acoustical performance.

There are numerous look-alike products that have a similar appearance, but are lacking in performance. Many of these copies are of much lower density, which keeps costs down, but severely diminish the absorptive performance. This is especially true in mid and low frequencies.


We hear many, many horror stories of folks who have gone with ”other” foams only to find little foam ”crumbs” all over their gear – sometimes in a matter of months! Our ”secret recipe” of acoustical foam minimizes this effect. This is highly dependent on the environment in which the panels are in – temperature and moisture changes are the biggest causes of premature ageing. Placing the panels in direct sunlight will also affect them negatively. Nankarrow as been around for over two decades in some installations and it shows no signs of deterioration. ”As good as new!”

Flame Retardancy

You may or may not have read disclaimers on ”other” foams about how they are ”flammable.” We strongly suggest that you take a matchstick or lighter and try to set fire to any acoustic foam you buy! You will find that Nankarrow foams have serious flame retardant properties. Several of our products achieve the highest possible by polymeric acoustical foams – Class A*. The foam will ”self-extinguish” if briefly exposed to a flame.


Ever been to a studio that used bedding foam for treatment? Looks cheap, doesn’t it? Well, Nankarrow offers a wide range of colors and shapes of acoustical foams to meet almost anyone’s tastes. All designs yield looks that are consistent with state-of-the-art décor and high-class tastes. Please browse through the many installation photos to see just a small sampling of the different ‘looks’ you can get!
