Acoustic Glazing Cut To Size

Sound reducing glass windows for noise reduction.

Acoustic glass has the main function to reduce noise levels. It soundproofs against external noise such as traffic, loud passersby, the weather and animals , allowing for a quieter environment. Nonetheless, this glass can also be used for interior windows, such as in office spaces, acting as a soundproof partition between rooms or offices.

Acoustic Glass Windows

Acoustic glass windows also offer superior security than normal double glazed windows. It is constructed with a PVB internal layer which means that the glass will not shatter into small fragments after a simple strike to the glass.

Commonly, the sticky middle sheet will hold together the broken pieces upon breaking This will reduce the risk of injury from flying glass fragments as well as preventing easy access through the window, therefore providing greater security.

For Many Applications

Whether it’s uPVC or timber, acoustic glazing can be installed in many different types of window profiles and frames. As well as this, the glass can come in various thicknesses and you are able to have it cut to size according to your needs.

Soundproof Glass Windows

Sound proof windows are usually referred to acoustic windows or noise reducing windows. Therefore, it is important to understand that these windows are not completely soundproof and are designed to reduce sound as much as possible. That is why we use the terminology sound reduction instead of soundproof to accurately describe our acoustic products.

Noise Reduction dB Rating

The results for our acoustic glass and glazing are exceptionally good and bring external noise to acceptable levels in noisy environments. There are different levels you can achieve starting from a 36 decibel noise reduction for an acoustic double glazing unit to a higher value depending on the thickness of glass used.

FAQs

Yes, it is possible to reduce sound in your existing double glazing windows, but it depends on the current setup. Double glazing is effective at insulating against noise, but you can enhance its performance further by using acoustic glass. Replacing one or both panes with thicker acoustic glass can help block more sound waves.

While you may not achieve full soundproofing, this upgrade can make a noticeable difference in reducing external noise, particularly from traffic or loud environments.

The cost of soundproofing windows varies depending on the method used and the type of window you have. For a standard window, here are some options and their costs.

Acoustic glass:

Replacing existing glass with thicker, laminated acoustic glass can range from £100 to £900 per window, depending on the size and specifications. Sound reducing panes are usually 6.4mm but can go up to 8.8mm for better noise insulation but will have an effect on the price. 

Secondary glazing:

Adding an additional layer of glazing (secondary window) is a more affordable option for enhancing sound insulation. This does depend on the space available to install the secondary glazing which may not be a viable option for you. We currently do not offer this product.

Sealing gaps:

Simple fixes like sealing window frames with acoustic caulking, filling gaps with acoustic expanding foam or adding weatherstripping are less expensive, on average around £50 per window.

Overall, full soundproofing, or sound reduction which is the correct terminology, can be a significant investment, especially for multiple windows, but even small adjustments can offer noticeable noise reduction within a reasonable budget.

Replacing your whole window for noise reduction can be effective but isn’t always necessary. Full window replacement is ideal if your current windows are outdated, poorly sealed, damaged or not double glazed. New windows with acoustic or laminated glass, larger air gaps between panes, and proper sealing can significantly reduce noise. This option also enhances energy efficiency and security.

However, replacing the entire window is costly, typically ranging from £400 to £1200 per window, depending on the size, materials and installation. Before opting for a full replacement, consider more affordable solutions like upgrading only the glass to acoustic gkazing.

If your current frames are in good condition, you might achieve similar soundproofing results with less expensive modifications, making a full replacement only necessary when your windows are very old or structurally unsound.
