Soundproofing in a metropolis: how to choose windows for a comfortable sleep

15.06.2025

In the conditions of the city bustle and constant traffic, the road to a quiet rest often lies through high-quality windows. The level of sound insulation is determined not only by the type of glass unit, but also by the combination of the profile, seals and correct installation. When choosing windows for the bedroom, it is important to understand which parameters affect the efficiency of noise absorption and how they are combined with each other.

The first step is to determine the sources of sound. Tram rails, multi-lane highways or night clubs create different acoustic loads: low-frequency hum, sharp blows or a constant background. There are optimal solutions for each type of noise. Low frequencies are better dampened by a massive multi-chamber glass unit with alternating layers of different thicknesses, and sharp sounds - by glass with a laminated intermediate film that holds back noise vibrations.

The window profile is no less important. IMZO aluminum and plastic frames are equipped with special thermal inserts and reinforced walls, which, along with thermal insulation, reduce the "transmission" of vibrations into the room. The number of chambers in the profile is of particular importance: each air chamber creates an additional barrier for sound waves. In combination with the correct selection of double-glazed windows, this allows you to achieve sound insulation levels of over 40 dB, which is considered sufficient for a peaceful sleep even in the center of a metropolis.

Seals and fittings are often underestimated, but it is the tightness of the seams that determines how street noise will penetrate into your bedroom. High-quality EPDM seals remain elastic when the temperature changes and do not lose their tightness for decades. Multi-point locking mechanisms additionally press the sash to the frame along the entire perimeter, eliminating gaps and "bridges" sound waves.

Window installation is the third key stage on the path to silence. Correct installation requires taking into account the unevenness of the walls, humidity and the actual thickness of the slopes. IMZO specialists use anchor fasteners designed for dynamic loads and two-stage sealing: internal vapor barrier prevents condensation, and external waterproofing does not allow rain moisture and street noise to pass through. The final adjustment of the sashes and checking of the seals are carried out after the shrinkage of the building and seasonal temperature fluctuations.

Additional elements can significantly increase the effect of sound insulation. Installation of external roller shutters or sound-reflecting blinds creates an active barrier and reduces noise by another 5-7 dB. Internal decorative panels with acoustic properties help distribute the remaining vibrations, increasing comfort inside the bedroom. Integration with a “smart home” will allow the roller shutters to close automatically when a specified noise level is reached or at night.

Maintaining the stated characteristics is only possible with regular maintenance. It is recommended to lubricate the fittings once a year and check the seals for wear or mechanical damage. If necessary, IMZO specialists will promptly replace worn elements and re-adjust the sashes so that your window does not lose its soundproofing properties throughout its entire service life.

Choosing windows for a comfortable sleep in a metropolis is a complex task in which the quality of materials and professional installation work in tandem. IMZO windows with a well-thought-out double-glazed window, a sealed profile and precise installation will become a reliable shield from city noise and guarantee a calm atmosphere in your bedroom. Any night, even in the busiest area, can become a real rest.
