Acoustic Draught Seals

Draught seals from Trade Timber Windows and Doors London are one of the most effective solutions for reducing draughts, air movement and subsequent noise. This type of external draft-proofing works by filling voids around a window’s security bars and lock, with an acoustically sealed material that is designed to stop unwanted noise.

In addition to excellent noise reduction, the low u-values of these windows will also help to keep your home warmer in winter, making them a great investment.

Secondary Glazing

Get some peace and quiet no matter how loud things get with secondary glazing. We create noise-reducing secondary glazing that can reduce external noise pollution by up to 80% which is 54dB, making a vast difference. With improvements in technology, we are able to improve the acoustic performance of secondary glazing by a huge margin.

Acoustic Glass

Acoustic glass mainly reduces noise levels from outside the home and improves aesthetics. Acoustic glass works by absorbing sound and vibration with a layer of air between its two layers of glass. This glass is also much stronger than normal glass, making it less likely to get damaged in a break-in. With our acoustic glass, you will have the confidence of knowing that your windows are fortified with effective, sound insulation to help guard against the high levels of noise pollution in today’s world.

Sash Windows Replacement

We replace your sash windows with bespoke high-performance noise reduction sash windows. Using this approach for noise control, the original appearance of the historic windows can be maintained within a cost-effective balanced design.

Frequently Asked Questions

Do you need planning permission for soundproofing sash Windows?

If you replace your sash windows with like-for-like replacements, then in most cases planning permission will not be required.

Can acoustic sash windows be installed in conservation areas?

Yes, they can. Acoustic sash windows are designed and manufactured to be as unobtrusive as possible. They come in a range of colours with subtle detailing for use within conservation areas.

Is it possible to retrofit acoustic glass in ordinary sash windows and double casement windows?

It is possible to retrofit acoustic glass in ordinary sash windows and double casement windows. The house that the windows are situated in can also have a soundproofing treatment applied such as the installation of an internal or external acoustic (usually fibre) batt within the wall space. When this has been completed, a layer of acoustic glass can then be applied to the surface area of the window itself.

Can I install acoustic glass in my sash windows?

Acoustic glazing can be installed in either single or double-hung sashes. Acoustic glass units are suitable for residential as well as commercial applications. Acoustic glass can be used in sash windows that are normally used to open.

Can you really hear the difference after soundproofing?

Yes, you can. We use modern technologies that acoustically dampen sound from the outside or inside and improve sound quality inside of your home after installing unique acoustic windows that help you achieve an unparalleled level of high performance and peace of mind.

How effective is acoustic glass?

Acoustic glass is more than twice as good. Acoustic glass reduces noise across the frequency spectrum at low frequencies (particularly unpleasant unwanted frequencies) and high frequencies. It’s the world-leading noise protection enhanced by double glazing.

How do you measure the effectiveness of acoustic glass?

A great way of measuring the effectiveness of acoustic glass and glazing at absorption is to calculate the R-value, it’s a universal unit of measurement that can be used to determine the effectiveness of a material in absorbing noise. Controlling sound is critical when it comes to designing and fitting acoustic glass and glazing systems; with the addition of mass in the glass system, you can achieve up to 75% sound reduction.
