Acoustic Secondary Glazing

Did You Know?

Many people would advise that triple or double sealed pane of glass would have a greater sound deadening ability. Unfortunately, triple or double glass only offers a very slight enhancement over standard single pane of glass due to the glass that is commonly used as well as the very minial cavity between the panes of glass and not a good way to soundproof windows. This is where Acoustic Secondary Glazing is different and offers a significant amount of noise reduction, this is achieved by placing the Secondary Glazing Window preferably at least 100mm away from the existing window. The cavity combined with the Acoustic Glass used in Secondary Glazing can achieve up to 80% in noise reduction.

Working Conditions

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 mm to 150mm 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.

Acoustic Soundproofing Windows with Secondary Glazing

Acoustic Secondary Glazing is a great way to provide acoustic insulation and a great way of soundproofing the windows from everyday activities such as traffic, pedestrians, airplanes, pubs and clubs.

Secondary Glazing provides better sound reduction as well as heat insulation than standard double or tripple glazed windows and many would consider it essential for houses close to busy roads or other high noise generating areas. When considering windows there are generally three options available for maximum achievable sound reduction:

6.4mm, 6.8mm, 8.8mm, 10.8mm or 11.5mm Thick Stadip Acoustic Glass (with a interlayer of Polyvinyl butyral).

A wider airspace between the windows. Preferably the combination of all two above.
