What is LOWE glass

There are many types of glass, one of which is called LOWE glass, which is widely used in energy-saving doors and windows. This type of glass can significantly improve the energy-saving effect of glass and is a good energy-saving product.

Many people know about this type of glass, but they don't know the specific details. To understand LOWE glass, one needs to know what coated glass is. Coated glass is the process of coating one or more layers of metal, alloy, or metal compound thin films on the surface of glass to alter its optical properties and meet specific requirements.

Low-E (Low Emission Glass) is a type of coated glass, which stands for Low Emission in English. There are two main types of Low-E glass: online Low-E and offline Low-E. Online Low-E glass refers to the coating process completed on a float glass production line, usually using chemical vapor deposition.

Chemical vapor deposition (CVD) is a process in which a reactive gas is introduced into a float glass production line to decompose the hot surface of the glass and deposit it uniformly on the glass surface to form a coated glass. The characteristics of this method are low equipment investment, easy regulation, low product cost, good chemical stability, and the ability to perform thermal processing. It is one of the production methods with promising development prospects.

Offline LOWE glass refers to the coating production of float glass after it leaves the production line. This coating method usually adopts the process of vacuum magnetron sputtering, which allows the particles of the target electrode material to bombard the silver on the silver electrode at high speed under certain vacuum conditions and gas atmosphere, producing a certain thickness of silver film on the glass and forming a special film layer together with other target electrode film layers.

The heat transfer coefficient of offline LOWE glass is slightly better than that of online LOWE glass, and there are more offline LOWE glass in the market. LOWE glass can be divided into single silver, double silver, triple silver, etc. based on the number of silver layers. The schematic structure of a single silver LOWE is as follows:

When processing offline LOWE glass into insulating glass, it is necessary to remove the film at the edge of the adhesive to prevent oxidation of the film layer. The main functional layer of LOWE film is the silver layer. Why are there several layers of film layer? The main purpose is to protect the silver layer from oxidation. If the silver layer is oxidized, LOWE glass will lose its energy-saving effect. Online LOWE glass is coated on the production line, which tightly binds the film layer to the glass. The film structure is relatively stable, and there is no need to remove the film at the edges when making insulating glass.
