Noise-reducing windows

Our noise-reducing glazing gives homeowners peace and quiet and peace of mind in one fell swoop. Perfect for busy areas in London where road and pedestrian noise can be a serious nuisance – our soundproof glass installation is your ideal solution.

Harnessing the unique potential of our specialist, laminated glass

It’s fair to say that no one appreciates the constant noise of passing
vehicles, sirens, and people going about their business at all hours, even if
you’re well and truly accustomed to it after years of city life!

Our noise-reducing windows and soundproof glass are specially designed
to keep exterior noise levels down, whilst being structurally tough and a
perfect-fit for your existing frames, whether they be timber sash windows
or modern casement windows.

How does noise-reducing glass work?

Glass thickness

Ranges from 3 – 8mm. The thicker the glass: the better it performs in reducing noise! This works in tandem with the specialist inter-layer, which is laminated between two panes of glass of different thicknesses, ensuring optimal performance. You can expect quality laminated glass noise reduction from us

 A specialist inter-layer:

A thin (~0.76 mm to 1.14 mm) layer of polyvinyl butyral (PVB) is laminated between the sheets of glass. The PVB works by dampening sound waves and vibrations, which it achieves without reducing any light transmittance and without being visible to the naked eye.

Draughtproofing

Draughtproofing reduces noise ingress by 6 – 10 db. This is achieved by sealing the gaps around the windows and door: holes which could equate to a sizeable hole in the centre of the glass.

All round Superb

" I used London Sash Windows and Doors to replace some old timber sash windows. They were superb to deal with, from start to finish. The initial meeting was very efficient. They explained to me that it was not necessary to replace the complete window box, which led to a significant cost saving. The team that arrived on the day were friendly, got the job done swiftly and left my flat cleaner than when they arrived. The windows have substantially reduced noise, the flat is much warmer and my condensation issues are fixed. I wouldn't hesitate to recommend London Sash Windows and Doors to anyone."
