The soundproof windows three elements: 1, frame in contact with the concrete wall and within the framework of the seal. 2, within the frame, and the inner frame of microleakage. 3, soundproofed windows, glass type soundproof windows Note soundproofed windows, water tightness, air tightness, wind pressure and noise attenuation. Soundproof windows, but the effect is not a panacea. Because the principle of soundproof windows is installed on the frame material efforts adhesions, and then with a thick glass barrier, indoor and outdoor noise. In general, the double window must be better than the single-window sound insulation and soundproof windows is far superior to another window, another soundproof windows tightness than ordinary window. Usually ordinary window can into a glass, the maximum thickness of about 8mm, but in the face of more than 80-90 decibels (dB) of noise, or can not achieve full mute. Above only for 8mm glass portions not contain Aluminum window slit factors. So, ordinary window in the closed state, can reduce the window audio dozen decibels, Bebel static sound soundproof windows can reduce 41 decibels. Therefore, aluminum windows gap is small, it is important under the conditions of heavy acoustic BER glass and soundproofed construction quality sound insulation to ensure extraordinary. Choose the expensive soundproof windows, soundproof windows in the conditions of a limited budget can also choose 10 mm acoustic BER glass. In order to make you spend money incision priority should be given to installing a sound-proof windows, home study and bedroom. Soundproofed windows in the domestic and foreign companies are many, varied, and therefore, should be a small gap between the purchase thick the BER glass soundproof windows, excellent construction quality is the primary condition. Second, the noise preferential proportion should be noted that, to find a good soundproof soundproof windows in a limited budget, of course, is the ideal situation, but can not make the event. Why soundproof windows prices high? High cost, difficulty of construction, expensive the Bebel static soundproof glass are reasons. According to the construction site, the noise frequency (Hz), and the sound of the noise, size (dB), and you need to soundproof subtraction, choose the BER glass thickness, budget-conscious, good construction quality changes, I believe you can make your maximum price effective than!
