Acoustic & Laminated Glass

Acoustic & Laminated Glass
At Express Glass Warehouse, we provide both acoustic glass and laminated glass for projects big and small.

Laminated glass is a popular type of safety glass, holding together in the event of breakage – available in a range of colours and thicknesses.

Depending on your requirements, EGW can supply both acoustic laminated glass or laminated glass to suit your every need.

This includes any shape or size, with glass thicknesses ranging from 6.4mm to 13.5mm.

Not only can you find a tailor-made solution at EGW, but you can also purchase the necessary glass fixtures and fittings to complete your project, making us your one-stop-shop glass experts.

Acoustic Laminated Glass

Noise Control Diagram - Pilkington

Acoustic laminated glass is specifically designed to reduce noise pollution, providing a sound barrier between an inside area and external noise sources. This type of glass is typically used in airports, recording studios, and meeting rooms.

The acoustic glass works in two ways: reflecting noise back, and absorbing most of it within the polyvinyl butyral (PVB) interlayer. Increasing the thickness of glass can further reduce noise pollution.

Why not try the Pilkington Sound Simulator to test the noise levels for yourself? 

What are the benefits of acoustic laminated glass?

  • Custom acoustic glass from EGW provides security, sound reduction, and thermal efficiency
  • Dramatically reduces noise pollution whilst also being very difficult to break, holding together after impact
  • Ideal for use in busy urban areas with increased road and foot traffic, including nearby railways, airports, factories, or pubs and clubs
  • Helps to soundproof indoor spaces like recording studios, private meeting rooms, and play areas, or reduce sound transfer with office partitions
  • Can decrease the sound of weather such as rain on skylights or roof glazing
  • Increased thermal insulation means it’s also more energy efficient, reducing energy bills

Laminated Glass

While acoustic laminated glass targets noise pollution, the job of regular laminated glass is mainly to protect against physical force and the breakage that usually results from such impacts. A single pane of glass would simply shatter into shards, posing a danger to everyone around.

It takes a larger amount of force exerted on laminated glass to crack or break, and in the rare event that this happens, it won’t shatter everywhere. The special EVA interlayer will hold the glass together, keeping the pieces in place for optimum safety and security. 

What are the benefits of laminated glass?

  • Extremely difficult to break; the inner plastic layer can hold shattered glass together
  • Ideal where security glass is required as a high impact barrier, such as shopfronts, outdoor balustrades and balconies
  • Can be used for walk-on glass flooring or stair treads, glass balustrades and Juliet balconies
  • Also perfect for glass furnishings like tabletops and shelves
  • Better at keeping noise out and keeping heat in

Additionally, laminated glass is highly customisable. We can provide a range of thicknesses from 6.4mm to 13.5mm, with the following types of finish:

  • Clear
  • Soft Coat
  • Diffused
  • Grey
  • Bronze
  • Acoustic

Acoustic & Laminated Glass FAQs

Acoustic laminated glass is usually implemented as a noise reduction solution in high-traffic areas. Many of us live and/or work in urban environments where noise pollution is a growing concern – the constant disturbance from nearby loud sounds can cause distraction, stress, and sleep disruption.

Whether your building is close to a main road, shopping centre, train station, or airport, or you just have especially loud and anti-social neighbours, acoustic glass can provide relief from nuisance noises in situations like these. This type of glass can significantly reduce levels of unwanted noise.

Since it’s often used for exterior applications to block out external sounds – such as glass windows, doors, and walls – acoustic glass must also be laminated for security purposes. This makes it thicker and stronger, keeping noise to an acceptable ambient level while preventing it from shattering.

Laminated glass is known for close-to-unbreakable properties, sandwiching a bonding interlayer typically between two layers of toughened glass. This construction makes it safer, because it won’t break into sharp shards on impact, but it also provides more barriers that external sound has to travel through.

Offering more insulation than single-layer laminated glass, reduces most sounds that would come right through standard glass. For the best possible sound absorption, you’ll need more than regular lamination. Upgrading to specially designed acoustic laminated glass improves the noise reduction.

This type of glass is laminated using a PVB (polyvinyl butyral) interlayer, which enhances sound insulation without affecting impact resistance or light transmission. This layer both reflects and absorbs sound vibrations to stop them from passing through, and also improves thermal efficiency.

Although laminated glass will offer a noise reduction, acoustic laminated glass may be the solution for maximum efficiency. Modern PVB interlayer technology is better than traditional resin at insulating against sound transfer, and the thicker the glass, the more it can dampen sound vibration.

However, it’s important to note that soundproofing glass is only as effective as its frame. If there are unsealed gaps around windows or doors, or the building envelope is too thin, then sound can find a way through anyway. When installed correctly, acoustic laminated glass can be extremely effective.

Acoustic glass is given an ‘Rw’ value according to the Weighted Sound Reduction Index, which rates its noise insulation effectiveness in decibels. The higher the Rw value, the better. Acoustic laminated glass at least 12mm thick can reduce noise by up to 50dB. At EGW, we use Pilkington Optiphon™ glass (formerly known as Pilkington Optilam™ Phon), which has an average Rw value of 45dB.

Thin panes of glass can only absorb a small amount of sound vibrations before allowing the rest to travel through, so acoustic grade glass has to be laminated with an insulating interlayer to absorb and dampen much more of the noise. This means that all acoustic glass is a type of laminated glass.

The difference is that not all laminated glass is acoustic, just it’s a form of toughened glass, but not all toughened glass is laminated. For laminated glass to achieve acoustic grading, it needs thicker layers of glass or asymmetrical thicknesses, and an improved insulating material for the interlayer.

Consider acoustic glass to be an upgrade from standard laminated glass. The ‘sandwich’ method of construction is more or less the same, and both types visually look like any standard pane of glass, but laminated glass isn’t as effective at reducing noise unless the sound insulation is optimised.
