Product Description

For premium projects where excellent sound absorption is required along with minimum weight, we offer Nankarrow GeoFill™ polyester wadding acoustic rolls and boards. These sheets are created from natural polyester fibers. These are known for their durability and reliable performance. Nankarrow GeoFill™ is used as backing material for drop ceilings, walls, and floors in premium recording studios, offices, and in the loudspeaker building industry. We offer 500 to 2000 GSM range.

GeoFill™ is made from natural polyester fiber thermally bonded to provide the rigidity and porosity required for broadband acoustic absorption. Due to no chemicals being used during manufacture, they are naturally fire resistant. These high performance acoustic polyester insulation batts help with reducing unwanted noise transfer through walls & ceilings to create quieter living spaces, for higher noise level situations, particularly suitable for media rooms or between floors. The 2000GSM variants have an NRC rating of NRC0.95 Polyester is a safe, non toxic, allergy friendly, light weight material that has high tensile strenth, robsutness & is unaffected by moisture. Nankarrow polyester batts are itch free, contain no Formaldehdye Binders, require no protective clothing to install, making them a safe insulation option for you & your family. Polyester Acoustic Insulation Batts also have a Zero Ozone Depleting (ODP) rating, contain negligible Volatile Organic Compunds (VOC’s) and 80% of the fibers that go into these polyester batts are recycled from plastic bags & other packaging materials, so they are safer for the planet too. GeoFill also meets the ASTM E84 standard for fire safety

The best solution for drop ceilings

GeoFill™ drop ceiling soundproofing insulation above your ceiling tiles will dramatically improve the sound-blocking characteristics of any suspended ceiling. If you are tired of noise coming down through your ceiling or up through the floor from the basement below and you’ve already got a suspended ceiling (or can install one), GeoFill™ acoustic thermal suspended ceiling insulation can make your drop ceiling quieter in no time. With this revolutionary ceiling insulation you will immediately see the difference, feel the difference and most importantly hear the difference.

Unlike fiberglass and mineral wool insulation, with GeoFill™ there is no itching and no scratching, nothing but the velvety feel of the best insulation product ever. Can be handeld safely without gloves. These panels are developed with environmental friendliness in mind.

For beauty with ultimate sound blocking performance, use GeoFill™ in combination with Nankarrow polyester fiber ceiling tiles, or any generic mineral based soft ceiling panels to create a modestly priced designer ceiling that both sounds great and looks terrific. Not only that, GeoFill’s™ impressive 6.5 R-Value will significantly augment your existing ceiling tiles R-Value to help any room feel warmer in the winter and cooler in the summer – and that’s good for you and for your pocketbook.

  3. Good product, excellent quality and packing

    Manish Gupta

    purchased these to make 4inch acoustic panels for my listening room. The 2000gsm boards arrived in perfect shape and were actually very clean and easy to work with. This is the safest product available in India for acoustic insulation and recommended by my acoustic consultant from UK. I covered my panels with natural jute fabric (not bought from here) and they perform very well. If you place these strategically to eliminate early reflection points, you will be surprised at the results you can attain. Everything just sounds so much cleaner and the ringing and flutter has been greatly if not completely reduced. Topped with the black fabric, the panels look amazing and blend in to my room very well.

  4. Satisfied with performance and safety

    Kanishka Mathur

    I currently have 12 panels installed in my small HT room and have been experimenting for optimal results. So far I have primary reflections almost completely under control and now I’m creating bass traps for the corners. As I said, this particular brand and product (nankarrow geofill) is highly regarded in the audiophile community in my city. They confirmed that it is completely chemical free and does not use any binders, giving superior acoustic performance. You can’t go wrong!

  6. Top class

    Kaushik Agrawal

    I purchased Geofill to make acoustic panels for my listening room. Placed 4 panels at the first reflection point to the sides of the listening position, they work beautifully to widen the soundstage and lessen unwanted mid / high reflection bounce off the side walls. I also placed 2 panels, 2 inches thick, behind the speakers on the front wall.

    For front corner bass traps I am using same materials but these are 6 inches deep (used 3 panels per trap) and the bass performance in my room has improved nicely. This evens out the peaks and nulls in the room, especially since I dont like using EQ. Covered in fabric over wooden frames, they are light weight and blend in with room design nicely. Great product.

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.

It is understood that the use and suitability of the product is entirely the responsibility of the buyer or specifying engineer and as such, these parties agree to hold Aural Exchange, or its associated company, and/or officers, harmless from any responsibility whatsoever other than what is clearly outlined in this warranty.
This warranty is void if the product is found to have been tampered with or misused by the purchaser, and shall not apply if the product has been physically damaged intentionally or due to accident and/or neglect, including burns, cuts, water damage, fungus, mold, stains, or is otherwise abnormally soiled or unsanitary. Any problems that are caused by abuse, misuse, or weather-related destruction are not covered.

Also, consequential and incidental damages are not recoverable under this warranty. Additionally, the products listed below are not covered under this warranty: 1. Accessories & Enhancements 2. Installation Materials 3. Product Samples To minimise colour-fading of acoustic foam products due to exposure to oxygen and ultra violate light, carbon is employed during the colouring process. This does not guarantee the colour fastness of the foam component and you should expect the appearance to change over time. Colour fastness is not covered under the Warranty. This warranty does not cover damage to furniture or equipment caused by contact with or destabilization of the foam components or adhesives and hardware used for installation. Care should be taken when placing the product on finished wood surfaces or other surfaces to ensure there will not be a chemical interaction between the surface finish and the foam component.
