The essence of double glazing is that windows are placed in two rows in the window opening. Do not confuse with the usual Scandinavian windows, according to the principle of which carpentry windows of two frames are arranged. In this case, the plastic windows are connected in one single construction.
An important feature of double glazing with plastic windows is a slightly reduced light opening. This occurs only when windows of different sizes are installed in the same opening. Well, for the quality you need to pay. But, fortunately, this is the only drawback, besides, the light opening diminishes very slightly and there are solutions without reducing the light opening.
Each window in the second outline is always an individual solution, so standard installation technologies do not exist: sometimes only one window of two changes, sometimes both, in some cases the second window is made of special thin frames to open the first one through it. But most often the option is used, when a new window of a slightly larger size is attached to the already installed window with a preliminary recess into the escarpment and the windowsill. You can count on the double glazing companies for the same.

Solutions are better than double glazing, does not exist.
To express in figures the degree of protection against noise, unfortunately, is not possible. The level of efficiency depends on the type of noise, as well as on the performance of the windows used.
Which windows need to be used for the best result?
For the best sound insulation, it is necessary to use the widest profile in combination with a wide double-glazed window, in which all the glasses have different thicknesses. The wider the profile and the thicker the glass in the double-glazed window, the quieter the window will be.
Useful knowledge about the sound insulation of windows
In half the cases, the window that is already installed remains in its place and does not need to be changed. Only the window for the second loop is set. But it is not always possible to use the old window, so it is likely that it will not come in handy and will have to install both new windows in one opening.
How greatly dim the window’s light opening
Depending on the solutions setting the second thread glazing, different changes of the light opening. Often it is possible to solve the problem of noise insulation in general without changing the light opening.
