Harnessing the unique potential of our specialist, laminated glass

Our noise-reducing glass is a great way to improve your property value while being able to better enjoy your home. Soundproof glass from London Sash Doors & Windows is designed to reduce exterior noise levels while also offering a structurally tough laminated glass option - perfect to install in your existing frames.

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 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.

Very Impressed

All work was carried out efficiently and they cleaned everything up after them (including a tidy up at the end of day 1 - which we said was ok to leave but they said they liked to leave things in order!). We were very impressed by the quality of the workmanship and the pride they all took in their work. This is a family firm and it shows. We were given an estimate of two days but the work was completed in a day and a half as there were 4 in the team who worked together really well. I would highly recommend this company
