Acoustic reduction

Outside noise can be a real nuisance, and seriously affect your quality of life, especially in an older building where the original glazing may be quite thin.


Whether it comes from traffic, construction or just city living, noise pollution can impact on your living or working conditions. With restraints of living in a listed building, standard double glazing is not usually a suitable option when dealing with noise reduction - but secondary glazing is.

Adding an additional internal layer of Storm bespoke secondary glazing to a primary window will vastly improve the noise reduction to your building. Science has played a large part in the development and production of our window systems. We pride ourselves on the quality of our product, and the fact we have hard evidence of our secondary glazing’s heat retentive and resulting energy-efficiency attributes.

Following rigorous acoustic testing at Salford University, we now also have irrefutable proof of their auditory protective properties and can confidently declare our sealed glazing units are the slimmest on the market to offer such high-performance protection from both drafts and noise. 

Together with their ease-of-use and imperceptible installation, our window systems truly are leaders in their field for period homes, listed and historic buildings where the preservation of feature windows is of paramount importance.

Acoustic testing


The acoustic test procedure adopted follows that detailed in BS EN ISO 10140-2:2010 - “Acoustics – Laboratory measurements of sound insulation of building elements; Part 2: Measurement of airborne sound insulation.”

The test involved installing Storm’s glazing units in an aperture between two rooms, producing a known sound field in the source room and then measuring the resultant sound level difference in the receiving room. The tests covered a frequency range of 50Hz to 5,000Hz.

Results showed Storm glazing consistently reduced noise levels by 40%.
