Acoustic Glass Wool or acoustic fiberglass is lightweight and has excellent acoustic absorption even at low densities. Glass wool is created through a unique process, as small pockets of air are trapped by fine glass fibres to produce a reliable insulating material. Aural Exchange has become a reference quality supplier for our top quality glass wool and our annual supply capacity is over 200000 square meters.

Glass wool insulation, also known as fibreglass, is made from glass fibres. Glass is heated to very high temperatures until it melts, and is then spun quickly to create fibres. These fibres are then bound together to be used as insulation. The glass fibres create pockets of air which act as barriers to prevent heat loss because air is a poor conductor of heat. Glass wool can be found in batts and rolls, loose-fill insulation and also within insulation boards.


When comparing the two, glass wool has an R-value of around 2.2-2.7 which means it is moderately effective at preventing heat loss through conduction.


If you’re looking at the most sustainable option, glass wool is generally made up of up to 50% recycled materials. As environmental impact and sustainability are becoming more of a focus, this is becoming more of an important factor when choosing the right insulation material.

Sound Proofing / Sound Insulation

In terms of sound insulation, mineral wool is often the preferred choice for noisy areas. This is because it is cheaper and denser than glass wool, so much less sound travels through the insulation.

Ease of installation

If you’re considering installing the insulation yourself, mineral wool is considered much easier to handle. Although heavier than glass wool, mineral wool is much easier to cut, move and fit into place. Glass wool on the other hand is limper, which makes it hard to fit into the spaces required.

Advisory: India has the most dubious quality of glass wool available in local markets. When working with or installing ordinary Indian glass wool from the local market, the small fibers can be swallowed or inhaled, where they may remain in your lungs for long periods of time, potentially leading to health problems. Further, you will experience severe itching on the skin and throat and may have spells of feeling dizzy due to the formaldehyde present in local variants.

To mitigate these health risks, we recommend using high quality internationally certified glass wool. We only keep the highest grade of glass wool from reputed international brands like Knauf and Nankarrow. By spending just a little more, you can safeguard your health and also the environment, because our glass wool does not contain any added formaldehyde.
