Soundproof Windows

Live on a busy road?

Living on a noisy road and don’t want to move? Trying to block all the annoying noise from outside has been a headache for most people in such cases. Especially experienced by people living near busy roads, entertainment areas, airports and railways. Well, people sometimes are not aware that they can soundproof their windows and block all the nuisance. Windows are being one of the weakest points in a home when it comes to sound insulation and considered first when assessing one’s home for the sources of noise pollution. Soundproofing has been proved to reduce noise levels up to 80%. Soundproof windows are second windows fixed behind the existing window and function just like the current window and do not require replacing the existing windows. The best option to go for when it comes to soundproofing windows would be installing sound proof secondary glazing with specialist acoustic glass, which is the best value for money when comes to tackling the issue..

Existing Window VS Soundproof Window

Your initial window is likley to have a standard 4 mm thick glass pane that will reflect some of the noise but not the majority. By fitting secondary glazing approximatly 100 to 150 mm away from the existing window will reduce noise by up to 80%. The cavity between the two windows will absorb a large percentage of the noise and the 6.4 or 6.8 mm thick Stadip Acoustic Glass used within the secondary glazing will reflect further sound waves.

What is Soundproof Secondary Glazing Window

Soundproof Windows

Secondary Glazing Secondary glazing involves adding a slim second window to an existing window. It is a cost-effective way to insulate and soundproof windows especially within listed buildings and conservation areas. Secondary glazing has been proofed to have a lot of benefits and many homeowners are been encouraged especially in areas that have restrictions on the installation of double glazed windows. Secondary glazing is also encouraged in areas where there is a lot of traffic noise, people can be heard talking after hours, construction sites, in buildings where it would be difficult to modify the current external windows such as the single glazed timber sash windows or single glazed metal crittall windows. The best part about secondary glazing is that it can be manufactured in a wide range of styles, shapes and colours so as to match the current windows and blend in and retain the external character of one’s property. The acoustic glass within secondary glazing acts as a form of double-glazing but with a bigger cavity through trapping the air between itself and the existing window and creating vacuum barrier. The secondary windows contain robust frames that firmly close thus providing a tight seal that timber frames aren’t able. Fitting secondary glazing to windows is considered less costly compared to double glazing and often fitted over newly fitted double glazed windows to provide better noise insulation that double glazed windows cant offer. When considering windows there are generally three options available for maximum achievable sound reduction:

6.4mm or 6.8mm Thick Stadip Acoustic Glass (with a interlayer of Polyvinyl butyral and thicker up to 11.5mm thick. 

A wider airspace between the windows.

Preferably the combination of all two above.
