Double insulated glass
When it comes to windows, you can't help but talk about glass. The previous windows are made up of single-layer glass or ordinary double-glazed glass. In recent years, hollow glass has appeared in China. Insulating glass was actually invented by Americans in 1865. It was used in the military. This kind of product has superior performance to ordinary double-layer glass due to heat insulation, sound insulation, sealing, frost resistance and dustproof. Recognition. In Beijing, there are currently regulations that should be hollow glass as long as it is close to the road.
Insulating glass seals two or more glass edges together, forming a static dry gas between the glass, and has a certain vacuum performance. Its main materials are aluminum alloy spacers, angled plugs, butyl rubber, polysulfide rubber and desiccant.
According to the experts of Meichi doors and windows, the sealing performance and thermal insulation performance of insulating glass are very good. It is mainly because of its special material. It is very simple to distinguish whether the insulating glass is qualified in winter. Just look at whether it is frozen inside or outside, if it is frozen. Not qualified. Because the insulation of the insulating glass is that the polysulfide rubber used can prevent the infiltration of water vapor; the butyl rubber can adhere to the two glasses to make it tightly sealed; the aluminum alloy spacer has a desiccant to absorb moisture.
Generally speaking, the effective life of insulating glass is 8 to 10 years. During its use, water vapor may infiltrate and water droplets appear. However, this is a long process. According to the state regulations, water vapor appears in the use of insulating glass for five years. Can be counted as qualified products.
At present, some high-end door and window brands in the market can be safely used, such as Merit, Garbo, Schwell and other brands. In some small factories, the insulating glass will produce inferior products. The so-called insulating glass simply fixes the two pieces of glass together. Consumers should carefully discern them. Do not affect the winter insulation.
