Upgrading your home to achieve reduced noise will probably require soundproofing your windows with double glazing or triple glazing acrylic glass. These types of treatments can be the quickest and most cost effective means to cut noise. Retrofitting a glazing system to the existing double windows is a proven means to sound proof glass from outside racket and can even be a great secondary means of soundproofing windows to achieve an even greater effect.
The double glazed window treatment creates an air cavity that acts as an insulation block for noise and energy loss. Depending on the size of the window and frame, the air break can be manipulated to be wider or narrower, to maximize the noise insulation. The sub-frame that you can insert will be made, most likely, of PVC and allows it to attach to almost any window frame, including wood, aluminum, and even steel frames.
An acrylic double glazing for soundproofing windows is up to six times more efficient for holding back noise than standard glass. A fully installed sound proof system using this type of system will cut back noise in any room it's used in, but will provide the maximum result if used on every window in the home. The best part about double glazing glass windows is the convenience they can offer. The window doesn't need to be replaced and when installed it can be also easily opened.
When talking about noise reduction and triple glazing there are three factors you should consider. The first is the thickness of the glass being used. Different thicknesses of glass will be able to block different frequencies of noise. The second factor is the gap between the double windows.
The larger the gap, the better the triple glazing will keep out unwanted sounds. By having two gaps, or three panes, it will attenuate more sound than just using double windows. The final factor is that the panes can have an inert gas filling in the gaps. If so, the gas itself will improve the soundproof windows ability to block or reflect any frequencies you find annoying.
If triple glazing is going to be the only means of soundproofing windows, then the idea of double glazing should be used instead. The air gap for double glazing is greater and will provide a better quality of sound reduction, keeping exterior noises from reaching the room you're in. Triple glazing should definitely be used just as a secondary means of treatments to soundproof windows.
When adding new acrylic windows it's a good idea to make sure the look fits the aesthetics of the home. If it doesn’t look decently, then it's almost not worth doing. Soundproofing windows can be a great idea, but when it clashes with the looks of the home, it's best to find a method that will add to the appearance and the noise reduction rather than benefit just one or the other.
In the end, the criteria that should be looked for is an airtight window with a storm window, it should be sealed properly to the surrounding wall, no ventilators whenever possible. There should also be a large air break between glass panes; having alternating thicknesses of glass will also help rebound the noise back to the source.
