Why choose soundproof windows<\/h1>\n\n\n\n

A guide to get to know the best models of soundproof windows and learn how to choose them. To improve the comfort of your home or office, pay attention to the acoustic insulation of your windows.<\/em><\/strong><\/p>\n\n\n\n

Excessive exposure to loud sounds is one of the most significant environmental problems in our noisy urban areas. This is noise pollution, a widespread problem in Italy. According to a survey by the portal Homepal, in a city like Milan, more than 40% of citizens are daily exposed to noise above the threshold of allowed decibels.<\/p>\n\n\n\n

Although little is said about noise pollution levels, a recent European directive requires European cities to commit to noise exposure maps and new noise plans. Excessive exposure to annoying outdoor noise can adversely affect quality of life and can cause health problems.<\/p>\n\n\n\n

To understand the level of noise to which we are usually exposed, just think that the screeching of a tram convoy can reach 80 db, the noise of a barking dog is at least 90 dB and that of a construction site where a jackhammer is used, reaches 120 db.<\/p>\n\n\n\n

To reduce noise pollution in indoor spaces, one of the most immediate remedies is to choose soundproof windows.<\/p>\n\n\n\n

What factors contribute to the sound insulation of a window?<\/strong><\/h3>\n\n\n\n

From a technical point of view, there are various factors that influence the good sound insulation of windows and it is precisely from the combination of these that the best performance can be achieved.<\/p>\n\n\n\n

From the type of glazing and its thickness, to the number of locking points and the presence of more or less powerful seals. Insulation is also influenced by the material of the frame itself, which can be made of wood, aluminium, steel or PVC. But how do you choose the most suitable anti-noise window frames? This guide will help you to find out which are the best sound-insulated window solutions.<\/p>\n\n\n\n

Requirements for sound insulation of windows with noise barriers<\/h2>\n\n\n\n

For the soundproofing of a window, the glass is the most important element as it consists of the 80% glass surface and the 20% frame and sash.<\/p>\n\n\n\n

 Glass for soundproof windows<\/strong><\/h3>\n\n\n\n

For a window or door to perform well in reducing noise pollution, it is necessary to take into account the characteristics of the glass panes. For sound-absorbing windows, it is better to opt for a double glazing with triple glazing or laminated glass.<\/p>\n\n\n\n

In order to be an effective noise barrier, glass must have certain characteristics. Such as adequate and diversified thicknesses between them. The diversified thickness is important to avoid the possible negative effects of resonance of the sheet.Whether the thicker glass is the one placed inside or outside, for sound insulation of windows, there is no difference.<\/p>\n\n\n\n

The size of the air gap between the two panes of glass is negligible. Instead, what affects it more is the thickness of the glazing and the internal films, since it is the mass that blocks the noise.<\/p>\n\n\n\n

The best soundproof windows are normally fitted with glass with acoustic plastic elements such as PVB (polyvinyl butyral), a plastic material, transparent and adhesive, used to join two laminated glasses. The one used for soundproofing glass is called \"special\" PVB, a film that is 0.50 mm thick and has an acoustic insulation power that is about 3 dB higher than traditional PVB.<\/p>\n\n\n\n
