Why Secondary Glazing Works!
The science behind secondary glazing
Here are just a few reasons why StopNoise Secondary Glazing works in shielding your home from unwanted noise:
- The ability to form a large 70 - 100mm air gap between your existing glass , and the secondary glass.
- It has dense weather pile seals on both sides of the sash to reduce noise infiltration.
- The large air space between the 2 panels of glass creates a cushioning effect. The use of 2 different thickness of glass also helps to change the frequency of the sound therefore helping to further reduce the noise to a baffled sound.
- The noise level will drop by 10 decibels in most cases which is perceived as a 50% reduction in noise levels.
- The use of other products like Roller Shutters, Heavier Glass and Cheaper quality Double Glazed units will not give you a better than 20% Noise reduction If you can’t achieve a minimum 50% reduction its not worth doing !
- The current building codes require you to insulate your Roof and walls but not the windows. In most cases the windows only have 3mm thick glass so it makes sense to insulate your window as well.
