Keep always in mind that standard windows are made from a single sheet of 3mm glass. This isn’t enough to give noise insulation. Using thicker glass can deliver some insulation. Double glazing offers the best protection against exterior noises, but some types of double glazed windows work better than others. Here’s what you need to know about noise reduction with double glazing.
The most effective soundproof glass windows are ones that are double glazed; that is, they consist of two panes of glass with a 20mm void in between. it is two panels of glass separated by an air or gas pocket. Standard double glazed windows have two panes of 3mm glass separated by a 6mm air or gas pocket. Of course, not all double-glazed windows can reduce noise at all. The thickness of the glass, the gap in between the panes, and how well fitted all contribute to their efficiency.
Below are some of the number’s researchers have come up with. Percentages are improvements over a standard 3mm single glass window:
- 19%: 4mm/12mm gap/4mm (voice noise reduction)
- 34%: 10mm/12mm gap/6mm (voice noise reduction)
- 46%: 10mm/12mm gap/6.38mm laminated glass
- 57%: 6mm/100mm gap/4mm (traffic noise reduction)
One of the commonest ways to slash noises is also the most efficient. Instead of replacing your windows, you can retrofit them with windows fitted on your current windows. The air gap among your existing windows and the new window is around 90 – 100mm. If correctly fitted with no air gaps, this type of double glazing can decrease traffic noise by up to 70 percent.
How Much do Double Glazing Window reduce noise?
Generally, People prefer windows and doors with double glazing thickness as “hush glass”. These frames are substantially better to wood and aluminum, which simply don’t cover properly. In fact, metal conveys noise quicker than any other raw material!
