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 for manufacturing acoustic panels, as backing material for drop ceilings, walls, and floors in premium recording studios, offices, and in the loudspeaker building industry.
GeoFill-XL™ is made from natural polyester fiber thermally bonded to provide the rigidity and porosity required for broadband acoustic absorption. No chemicals are used during manufacture. 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. Nankarrow GeoFill is 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.

Nankarrow GeoFill-XL™ Density for Acoustic Applications:
GeoFill-XL is superior to both rockwool & glasswool, because its fibers are not bound together with any chemical binder so they do not clump together. This allows extremely low flow resistivity values which helps you achieve the most linear absorption curve. This in turn helps create a natural sounding acoustic environment. Based on air flow resistivity values, we recommend the following thickness of GeoFill for your acoustic panels
- For 2″ to 4″ thickness use GeoFill 40 kg/m3 slabs (Air Flow resistivity 12800 Pa. s/m²)
- for 6″ to 8″ thickness use GeoFill 20 kg/m3 slabs (Air flow resistivity 9600 Pa. s/m²)
- for 10″ and more thickness use GeoFill 10kg/m3 (Air flow resistivity 6200 Pa. s/m²)
GeoFill-XL can be used in various places like Recording studios, Home theaters, Rehearsal rooms, Auditoriums, Dubbing rooms, Hotels, Server rooms, Restaurants, Schools & Colleges, Hospitals, Voice Over (VO) Rooms, Commercial places, etc.
How to Use:
Due to its light weight nature, Nankarrow GeoFill_XL™ can be directly placed inside, above or behind any kind of wall, ceiling, or floor panels. It can be stuck directly to walls and ceilings using a suitable adhesive and also be attached using Nankarrow ProPin™

Nilesh Naik –
Spoke to Ashutosh before ordering GeoFill-XL for home theatre panels. Product arrived in Pune within 3 days and quality is solid, much better than local options.
Prashant Gupta –
Used GeoFill-XL in my recording setup and results are satisfactory. Heavy material so installation needs two people but worth the effort.
Karthik Venkatesan –
Building bass traps for studio with GeoFill-XL and the thickness helps. Cuts clean with proper blade and stays within wooden frame without compression issues.
