In the specifications of Doors and Windows, the biggest correlation between the overall thermal insulation and sound insulation performance of doors and windows is the glass. Why do we say that? Because glass occupies more than 85% of the surface area of doors and Windows, so we should know the importance of glass. The choice of glass is generally configured according to the environment in which you are located, and the most commonly used is insulating glass, which can meet the basic requirements of most families for sound insulation and thermal insulation performance. You can also upgrade the glass specifications based on demand.
Multilayer glass
The role of insulating glass is mainly heat preservation and sound insulation. Insulating glass can block the exchange of indoor and outdoor air heat energy to a certain extent, so as to achieve the purpose of heat preservation. Cold areas are suitable for using three glass two cavity or even four glass three cavity to improve the thermal insulation performance of the window, winter is not too cold areas, ordinary insulating glass can meet the needs.
Argon
In addition to the glass , argon is also one of the optional items for window and door glass. Argon is an inert gas, density is greater than air, can prevent the temperature of the glass chamber body pressure reduction, resulting in glass self-priming phenomenon, can also prevent the expansion of insulating glass in hot weather, generally a single area of more than 2.5 square meters of glass self-priming phenomenon is more common, so large area of insulating glass is recommended filled with argon. Argon filling can also reduce the convection and heat conduction of the gas in the hollow glass cavity, and improve the effect of thermal insulation and sound insulation performance, so it is recommended to fill argon if there is a high demand for thermal insulation performance. Argon gas filled with glass is a dry gas, which can prevent the condensation of water mist in the glass cavity to a certain extent. Sealed qualified insulating glass, the annual escape rate of argon is about 0.1%-0.3%, the role of argon can be effective for more than 15 years, but the service life of unqualified insulating glass will be greatly reduced, sealed unqualified insulating glass, the interior will enter cold air and fog.
Laminated glass
Laminated glass is suitable for houses with sound insulation requirements, such as roads, schools, downtown areas, lower floors and houses along the street. The selection of hollow laminated glass noise reduction effect is better than three glass two cavity, if there is a higher demand for sound insulation, you can even choose double hollow laminated glass. At the same time, laminated glass can also increase the safety of glass, even if broken, the two pieces of glass in the PVB adhesive layer will be firmly fastened together. Bank counters use multi-layer laminated glass.
Tempered glass
Tempered glass is also called safety glass in the construction industry, which is basically the standard for high-rise residential Windows. China has mandatory regulations that seven floors and above residential Windows must use safety glass, generally in the window corner there are 3C logo and product identity code, according to the code can be queried to the manufacturer. In addition, it should be noted that tempered glass has a certain self-detonation rate. In addition, during the process of glass tempering, there will be stress changes inside the glass, and if the tempering process is not handled well, the water ripple on the glass surface will be particularly obvious.
LOW-E glass
LOW-E glass, also known as low-emmissivity glass, can block a part of the infrared rays in the reflected sunlight, so that visible light can penetrate, to achieve the purpose of heat resistance and light resistance, effectively reduce the thermal radiation effect of sunlight, and reduce the energy consumption of summer air conditioning. Suitable for places with strong sunshine and long sunshine time.
