The soundproof window is mainly a window that pursues energy-saving performance such as sound insulation, heat preservation and heat insulation. Yongduo soundproof window is equally good in wind pressure resistance, air tightness and water tightness, and its heat preservation and heat insulation performance is medium. However, ordinary windows, because of only a thin layer of glass and frame, and poor sealing, the indoor temperature will rise and fall rapidly with the change of outdoor temperature contrast, and the cold and warm air will overflow quickly, which will lead to rapid energy consumption and waste of expenses.
Scientific research shows that people prefer the sound environment below 6 decibels. When the sound exceeds 7 decibels, not only will they feel noisy, but also the hearing nerve cells will be damaged. At present, the country has the corresponding allowable range of environmental noise: the noise should not exceed 3 decibels at night (from 22: to 6: the next day) and during the day (from 6: to 22: ), and a survey of residents around the factory shows that the threshold of noise level that interferes with sleep and rest is 5 decibels during the day and 45 decibels at night.
The soundproof window is composed of glass and window frames with different densities. It is made of specially processed materials and has high temperature resistance and firmness. The glass used in Yongduo soundproof window is special glass, which is very different from ordinary glass. It can block 9% of ultraviolet rays and avoid the harm of skin epidermis caused by direct sunlight. And it also has an effective waterproof function, effectively preventing the corrosion of indoor furniture caused by moisture, and it can also resist the dust blown by the outside wind, so that the cleanliness can reach 1%.
Good thermal insulation: the plastic in the three-layer composite vacuum soundproof window has low thermal conductivity, and the thermal insulation effect is 125 times better than that of ordinary aluminum profiles. In addition, it has good air tightness. In cold areas, although it is MINUS ten degrees outdoors, it is another world indoors.
2. Good sound insulation: its structure has been carefully designed, with sealing strips imported from Britain, and the joints are tight. The test results show that the sound insulation capacity is over 4dB, which meets the national industry standards.
3. Good air tightness: each gap of the three-layer composite vacuum soundproof window is equipped with sealing strips imported from Britain, with air tightness of Grade I, which can give full play to air conditioning and save 5% energy.
4. Good sealing performance: the doors and windows are designed with rain-proof structures, which completely isolate the rain from the outdoor, and the water tightness meets the national industry standards.
5. Good fire resistance: the materials used in the three-layer composite vacuum soundproof window are all flame retardant materials, which are environmentally friendly and energy-saving.
6. Good anti-theft: the three-layer composite vacuum soundproof window is equipped with excellent hardware fittings, advanced decorative locks and toughened safety glass, which makes the thieves helpless.
7. maintenance-free: the three-layer composite vacuum soundproof window is not easy to be corroded by acid and alkali, and it will not fade for 2 years. It has been certified by authoritative experiments and hardly needs maintenance. When it is dirty, it can be scrubbed with water and cleaning agent, and it will be as clean as ever after cleaning.
8 Good design: The three-layer composite vacuum soundproof window is scientifically designed and adopts reasonable energy-saving profiles, so it has been recognized and praised by the national authoritative departments, which can add luster to the building.
at present, there are mainly insulating glass, laminated glass and vacuum glass on the market. Vacuum glass can reduce noise by 3-4 decibels by applying the principle that vacuum cannot transmit sound. If the floor is high, such as more than 2 floors and there are no trains or large trailers nearby, you can consider choosing insulating glass or laminated glass; If the floor is low and close to the road or viaduct and there are low-frequency noise sources nearby, then we should consider using Yongduo vacuum glass for sound insulation, so as to completely solve the noise problem.
in terms of sound insulation technology, sound insulation glass is only an element in the design of soundproof windows. We don't deny that sound insulation glass plays a great role in noise, but we can consider that Yongduo soundproof window can sound insulation because of its large area density and very heavy weight.
from this point of view, the sound insulation window with multi-layer glass has no advantages in terms of technology or sound insulation effect, which is also the reason why it has not been popularized in the market. At present, double-layer soundproof windows are the mainstream. For ordinary traffic noise, even train noise or airplane noise, the sound insulation capacity of double-layer soundproof windows is sufficient.
