The further acceleration of urban construction inevitably exacerbates the level of noise pollution. In particular, traffic noise accounts for up to 40% of urban noise. Many urban residents who accompany the road day and night are naturally “unforgettableâ€. Pursuing a quieter living environment and choosing some effective soundproofing materials has become a concern of many citizens. Steel doors and windows The sound insulation performance of the horizontally-sliding window depends on the tightness between the two windows and between the window and the window frame, and the opening of the window depends on the tightness of the closed window and the frame, and the plastic steel doors and windows are generally sealed by a rubber strip. Different from the "hard hit" of ordinary aluminum alloy windows, the sound insulation effect is more obvious. At present, there are various styles of plastic steel doors and windows. In addition to the traditional inner and outer swinging, push-pull and folding styles, there are also interiors that open and close the doors and windows, push and pull the hanging doors and windows, push and pull the lower hanging doors and windows. In terms of color, the common plastic steel doors and windows on the market are mainly white, because the white or gray PVC profiles have good weather resistance and light stability, but there are also colored profiles, and the decorative design has more freedom to play the space and be more personalized. Although the price is higher, the market potential is still huge. The sealing performance of plastic steel doors and windows is good, ensuring sound insulation. But it also brings weaknesses in the lack of air circulation. In response to this situation, the manufacturer developed a ventilator for closing the window, which does not affect the sound insulation and ensures the exchange of indoor and outdoor air. The ventilator can be installed between the window and the window line, and does not occupy a place. Prices range from 1,000 yuan to 6,000 yuan, depending on quality and specifications. If you want to switch the timing window, you may be selected on the market new time switch device. Its price is about 2,000 yuan. At present, the prices of plastic steel doors and windows on the market are mixed. Plastic steel windows are as low as 200 yuan per square meter, and imported products can cost more than 1,000 yuan. The price of plastic steel doors varies greatly, ranging from a few hundred yuan to more than 3,000 yuan. New aluminum doors and windows The average person thinks that the sound insulation effect of aluminum doors and windows is not good, but in fact, the new aluminum doors and windows have made great improvements in sealing sound insulation performance. The sound insulation performance of the window mainly lies in the sound insulation effect of the glass which accounts for about 80% of the area, and the sealing performance of the door and window. Some aluminum door and window products on the market cooperate with the principle of resonance and transmission of sound waves, and adopt different glass composite structures to enhance the sound insulation effect. In terms of the airtightness of the door and window structure, the use of high-quality rubber strips and plastic sealing accessories has also largely solved the problem of poor sealing performance of aluminum doors and windows. The coloring ability of aluminum doors and windows is strong. After special processing, it can make the effect of imitation wood grain and imitation granite, which makes the appearance of doors and windows more colorful and colorful, suitable for people's different decorative requirements. Consumers can choose products of different grades and price points according to different practical requirements, and the price range is about 300 yuan to 1000 yuan. Insulating glass The insulating glass is composed of two or more layers of flat glass, and two or more pieces of glass are bonded to the aluminum alloy frame or the rubber strip by a high-strength and airtight composite adhesive, leaving a space between the sealing glass. Inject inert gas for excellent thermal and acoustic insulation. Due to the poor heat transfer performance of the air or gas sealed in the glass, superior sound insulation is produced. Insulating glass can also be placed in different layers of the window to make a special decorative effect. It is especially common in villa renovations. Laminated glass Laminated glass refers to a PVB interlayer film sandwiched between two or more sheets of glass. The PVB interlayer film reduces the amount of noise that penetrates the glass, reduces noise decibels, and achieves sound insulation. For example, laminated glass made of Safles PVB plastic interlayer can effectively block the usual 1000 to 2000 Hz anastomosis noise. At present, the “Silent Villa†has been popular in foreign countries, and the use of laminated glass in foreign houses has already accounted for a considerable proportion. Sound-absorbing decorative panel sound-absorbing decorative board is a new type of building material that combines sound absorption and decoration. It has excellent sound-absorbing performance and flame retardant effect. Generally wide range of colors and patterns to choose from fabrics, some products may occur depending on design requirements sound absorbing body processed into various shapes.
