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.
