But i do not want so much, but that is not worse. There is a way, windows with energy-saving glass, the so-called I-glass, where the surface of glass microscope applied coating of various metal oxides, including silver. If you look at the certificate testing the most common glass to glass-and Top-N, we see that the single-chamber windows with a standard 24 mm thick with a single-glass has a coefficient of 0.66, but if you upload an inert argon gas, then all 0.69! And coating of energy-saving glass is almost negligible and the light transmittance in the visible spectrum is triple-pane windows with ordinary glass. Energy-saving glass, gives a few more positive effects. First 30% reduces the heating facilities of direct sunlight, and secondly, do not miss the ultraviolet rays, which prevents fading of furniture coatings. We now turn to the issue of sound insulation of the room.
If your windows face the courtyard or a vacation home, then the standard single-chamber glass for soundproofing, fully meet your expectations from the new windows. Want to draw attention that many firms is recommended for increasing the noise insulation properties of windows triple-glazed windows, arguing that the triple-pane windows provide soundproofing rooms 34dB, 26dB only a single chamber. In part, this statement is true, but only for high-frequency sounds (whistling cry baby), but for the low-frequency sounds, like a passing truck, sound insulation that a twin-, triple-pane windows that is the same and lies in the range of 24-25 dB, since the resonant frequency of vibration of glass coincides with the low-frequency noise and does not depend on the number of cameras.
