If you think the difference in noise levels between single glazing and double glazing is enormous, acoustic glazing will blow your mind.

Acoustic glazing is engineered to absorb sound and vibrations at all frequencies, so it’s better at stopping unwanted noise than other types of glazing. It’s perfect for noisy areas like city centres, motorways, train lines and airports.

How does acoustic glazing work?

Acoustic glazing consists of layers of laminated glass bonded together with a sound dampening core between the panes. This glass sandwich is a near-impenetrable wall that absorbs, reflects and dampens sound and vibrations.

The effectiveness of acoustic glazing is determined by the thickness of the product and the quality of the core. The core is meant to stop sound and vibrations from moving between panes, and the most common material is PVB (Polyvinyl butyral).

7 acoustic glazing benefits

  1. Extreme noise reduction

Standard acoustic windows have a dB rating between 32 and 38, around 20% better than standard double glazing, and better than triple glazing. As a rule of thumb, each additional mm of thickness reduces sound by 1dB.

  1. Soundproofing

Acoustic glass is better than double and triple glazing for soundproofing rooms like music studios and home cinemas. The material stops sound and vibrations both ways, helping to keep neighbours happy by keeping noises inside.

  1. Variety of thicknesses

Acoustic glazing is commonly available in thicknesses ranging from 6.8-12.8mm, making it suitable for most window boxes. Thicknesses above 6.8mm may require modification to the window box, to accommodate a thicker frame.

  1. Variety of styles

Acoustic windows can be manufactured in any style. They can replace sash windows, bay windows, bow windows and casement windows. Many standard designs are available, or we can manufacture custom windows for your home.

  1. Cheaper than you think

When comparing acoustic glass with modern double glazing, acoustic glass is around 20% more expensive, on par or slightly less than modern triple glazing. This may be suitable for your budget and we offer finance to spread the cost.

  1. Enhanced security

It is more difficult to smash through acoustic glazing than double and triple glazing because there is no air between the layers. The layers are bonded and laminated, creating a thicker, stronger product that is harder to penetrate.

  1. Good thermal efficiency

Acoustic glazing can be as thermally efficient as standard double glazing. There’s no gas between the panes, but the product is thick and laminated. It offers a good sound-thermal balance, weighted more heavily to the sound side.

Should I get acoustic glazing?

You should consider acoustic glazing if double glazing isn’t reducing sound and vibrations enough. One of our customers contacted us because they live near an airport, while another wanted acoustic glass because they live next to a train track.

You will typically pay a 20% premium for acoustic glazing over double glazing, in return for a 20% improvement in acoustic performance.

Whether acoustic glazing is right for you depends on whether its performance will meet your expectations for the price. Acoustic glazing makes a big difference, but like all glazing, it doesn’t eliminate sound and vibrations completely.
