Specifications, classification and functions of door and window
When installing plastic steel doors and windows, you can install two layers of glass, you can also choose to install single layer glass, or you can use double-layer insulating glass, but some consumers do not know the difference between double-layer glass and insulating glass.
1. General single-layer glass grid method and float method, thickness is 4 mm or 5 mm
2. Double-layer glass is the same as single-layer glass. The difference is that a sponge strip is used to separate the two layers of glass, but air will still enter, so there will be fogging between the two layers of glass!
3. The difference between insulating glass and double-glazed glass is that gas is filled between the two layers of glass, usually air, and then an aluminum frame containing desiccant (molecular sieve) is used around the perimeter, and PU glue is added to seal it. The effect is very good, and it does not cause damage in winter. It will fog up.
Generally speaking, the effective life of insulating glass is 8 to 10 years. During its use, water vapor may penetrate and water droplets may appear, but this is a long process. The sealing and thermal insulation properties of insulating glass are very good, mainly due to its special material. The method to identify whether the insulating glass is qualified in winter is very simple. Just check whether it is frozen inside and outside. If it is frozen, it is unqualified.
4. Vacuum glass is rare on the market. Because the cost is too high and the production process is complicated, it is only used in a few places.
