Sound insulation principle of soundproof windows: Sound insulation is the use of dense materials to isolate sound into a certain space. The noise reduction effect of sound insulation glass is called sound insulation performance. The harder the material is, the better the sound insulation performance of the glass. On the contrary, the loose glass of the material is very thin and the sound insulation performance is poor. Therefore, in addition to the sound-insulating glass, the sound density of the material with high density (multi-layer composite glass) is good, but the premise of sound insulation is to cut off the path of noise. There are two ways to transmit noise, one is air propagation, the other is object propagation, that is, building propagation. In the process of using the soundproof window, do not leave gaps, otherwise the noise will propagate through the gap, and the sound insulation effect will drop. Henan Bofu soundproof window uses a specially processed sound insulation layer, which is made of PVB film sound-insulating glass, which is firmly bonded by high temperature and high pressure. According to indoor and outdoor noise, 80 dB of traffic noise can be reduced. Extremely quiet to below 45 decibels. Sound insulation is especially good. The general sound insulation effect is between 30 and 35 decibels. Bofu soundproof window features advantages Installation of soundproof windows: Install the soundproof windows without removing the previous windows. Install them directly in the windows.

Bofu laminated rubber sound insulation window consists of: pvb laminated acoustic insulation glass + profile window frame + imported sound insulation sealing strip.
1, sound insulation: generally can reduce most of the noise, noise reduction performance of more than 80%, basically can not hear the outside sound in the living room.
2. Safety: The outer layer of the sound insulation layer of the window will only be cracked after being damaged by external force, and will not fall off or splash, and protect the surrounding people and objects from harm.
3, security: with explosion-proof, anti-theft, anti-ballistic effect, especially for malicious damage, theft and violent invasion have a good resistance and impact resistance. However, it is limited to the outer layer of the soundproof window. When the outer layer of the sound insulation layer is broken by impact, the outer layer fragments will be stuck by the PVB, which is not easy to injure, but forms a radial crack and maintains the original shape and visibility. You can continue to use it during the time.
4. Optical: Generally, the visible light transmittance ranges from 10 to 50%, and the reflectance is 13 to 25%. The sound-absorbing glass layer contains UV-absorbing additives that filter out 99% of the UV rays, which not only reduces the glare, but also prevents the fading of the interior decoration items.
5, energy saving: can effectively reduce the heat transfer coefficient U value. It can reduce the transmission of sunlight, reduce the cost of air conditioning, and save energy.
6. Sealing: It adopts the mature elastic structure technology of the United States to achieve the overall sealing performance as much as possible. It adopts butyl rubber and polysulfide rubber or structural rubber double-pass sealing to ensure the sealing and prolong its service life.
7, anti-condensation: the sound insulation layer is absolutely dry, no condensation.
8. Deteriorating fire: When the sound-proof window glass is heated and fired, it will not be broken and disintegrated immediately, resulting in a longer time limit of fire in one place, which is conducive to timely detection of alarm, evacuation and extinguishment.
