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 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.

    Improved flutter echo and general acoustics in my 12ft x 10ft bedroom. I have a live / recording / mixing project studio. Used with Nankarrow bass traps, very happy.

  2. Twice the mass of pyramid and wedge foam = twice the performance

    Sumiran Singh

    QUICK SUMMARY: Worked to deaden the reflected sound in a small nook of my bedroom that I’ve turned into a recording studio.

    BACKGROUND: I’ve turned an unused wardrobe space in my master bedroom into a home recording studio. The built-in space is walled-in on three sides with a large mirror behind the countertop. Without treatment, the sound was reflecting off all the hard surfaces. On a recommendation, I ordered NeoFill instead of going in for pyramid and wedges. It worked! The space I’m working with is approximately 3′ x 3′ x 4′ (Depth). Two sheets of 100mm were enough and my recordings are crystal clear. Ashutosh was helpful in explaining how I can cut the foam cleanly by myself.

    INSTALLATION: To attach the Neofill to my walls and mirror, I used Fevicol Heatx.

    PERFORMANCE: After installing just the squares on the three walls, I sampled my voice above the foamed walls and within the foamed walls. It was very, very noticeable the difference! My microphone Rode NT1 is picking up crystal clear sound, with good depth. My client ( a leading audiobook company) tells me the recordings are up to the mark.

    CONCLUSION: I’m not a musician or recording artist, just somebody who has a need to professionally record my voice at home without a big investment. To me, getting my room setup in under Rs 10000 really worked well.

Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.
