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.

Was recommended this as the best acoustic infill for studio builds by renowned acoustic consultant John Sayers, since it does not have any binding agents, so the flow resistivity is very close to theoretical predictions. Worked great and delivered before time. We tested the density and thickness and they were as advertised. Overall a good experience working with Ashutosh and Aural Exchange.

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.

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!

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.
