Classification of Soundproof Windows

1) Insulating Glass

Generally, people often think that the sound insulation performance of Double-layer Insulating Glass is very good. In fact, it is a misunderstanding. The commonly used Double-layer Insulating Glass is composed of two pieces of 3 to 6mm. The small hollow distance makes the air layer between the two glass appear stronger "rigidity", does not play the role of air spring and loses the general double-layer board structure advantage. At the same time, due to the resonance of the double-layer structure, the small hollow distance causes the resonance phenomenon to occur at middle and low frequencies, resulting in a decrease of the sound insulation. In addition, the market of Double-layer Insulating Glass in the production of aluminum or glass with more than two pieces of glass glued together, aluminum and glass of the "acoustic bridge" also makes the sound insulation performance degradation, so double-hollow The sound insulation performance of glass structure much better than the Single-pane Glass. Of course, it is undeniable that the insulating properties of double-layer insulating glass is better.

2) Vacuum Glass

The Double-layered Vacuum Glass and Double-layer Insulating Glass are basically the same in structure and manufacture, except that the Double-layer Insulating Glass has an air layer in between, and the middle of the Double-layer Vacuum Glass is "vacuum". First of all, the vacuum of Double-layer Vacuum Glass is very difficult to achieve, that is, the inner liner of a thermos flask, which is a vacuum-like product made in a special environment, and its thermal insulation performance is often not as good as people think, Double-layer Vacuum Glass, the more technical difficulty. Small and medium-sized manufacturers in general do not have the strength to produce Double-decker Vacuum Glass. If you can not or can not be long-term stability of the relative "vacuum", not as good as Double-insulated Glass effect, and, glass is a fragile items, get away is not a small sound, hurt people but a big deal . Therefore, people generally do not choose double vacuum glass to noise.

3) Laminated Glass

Double Laminated Glass is sandwiched between the two layers of glass in a layer of sound-absorbing material, so that the noise in the composite structure for multiple reflections and absorption, to achieve the purpose of sound insulation. If you then equipped with a good window profile, good window seal, Double Laminated Glass can often achieve good sound insulation. This method is technically advanced and feasible in practice. Therefore, the Double Laminated Glass has been generally accepted by people.

4) Polyester Glass

Polyester Shade Mute Glass, it is based on Double Laminated Glass sound insulation principle, the organization of the domestic acoustic industry's top experts after years of research and development and testing, and finally developed an economical and Practical Polyester Shade Mute Glass. Polyester Shade Mute Glass using the finest quality glass, the use of double or three-tier structure, independent research and development will have super "wall" sound-absorbing, sound-insulating properties of transparent polymer materials, with high-tech production process from composite. Polyester Shade Silent Glass sound insulation effect is ideal, in the same industry in the world in a leading position. And won the 2008 Olympic tour of science and technology outstanding product title.
