Description
The present invention relates to a triple-layered glass and a method of manufacturing the same. More particularly, the present invention relates to a multi-layered glass in which glass members are laminated in triplicate, and a manufacturing method thereof.
Typical buildings consist of more than 30% of windows and require different forms of glazing to match the appearance of more beautiful appearance and increasingly complex buildings. Therefore, insulation performance is required for window and glazing materials to reduce energy consumption of buildings. Various high-energy performances of glazing required for such a requirement, that is, constituent materials such as a glass, a bamboo, and a sealant constituting a double-layered glass have become important.
In addition, in the case of glass, the use of the low-temperature glass for effectively blocking the inflow energy into the room or the outside is effectively used, and the glazing sealant for the multi-layer is selected in accordance with various building shapes and window construction methods. As the development of building technology and the development and supply of energy-saving windows have increased, the life of the building has become longer, and importance and interest in durability have been increasing as well as performance. Spacer, Function is required.
In addition to high performance ROYE glass for satisfying high energy performance of less than 1.0 W / ㎡K required for recent windows, glazing which can satisfy the heat pipe rate performance by injecting triple layer structure and adiabatic gas, It is a reality that the demand for window that can be increased is increasing.
Generally, the spacer constituting the double-layered glass is made of an aluminum material and has a structure capable of maintaining the gap between the two sheets of glass firmly. However, recently, a plastic material or a composite resin spacer having a lower thermal conductivity than a metal material is applied The use of glazing is increasing.
Basically, the glazing structure for the construction of a window with high thermal performance requires the use of a double-layer glass consisting of one or more high-performance Roy glasses (two) and injecting argon (Ar) and expensive krypton (Kr) Performance, and it is not enough to perform below 1.0 W / ㎡K. Therefore, it is satisfactory to use one or two layers of triple-layered structure and Roy glass, and heat insulating elements such as insulating gas injection. As a result, the manufacturing process required for manufacturing a triple-layered double-layered glass is complicated and the risk of failure due to the additional process is increased compared to the conventional double-layered and single-layered glass and the method of producing a double- .

However, the conventional aluminum spacer is superior in terms of appearance and mechanical strength, but has a higher thermal conductivity than a spacer made of a plastic material. The spacer of the thermoplastic material is similar in thermal insulation to the spacer of the thermosetting material, but the restoring force is deteriorated by repetitive wind pressure There are disadvantages.
In addition, the external environmental load of the double-layered glass is maintained for several decades during the life of the building after the construction. If the fatigue of the edge suture due to the seasonal change and the change of volume of the gas inside the multi- Or deformation of the hollow bar may cause sealing failure, which may cause problems such as the internal condensation of the inner layer and oxidation of the roy coating surface. In particular, the risk of deformation of the double-layered glass sealing portion due to such environmental load may increase due to differences in thermal contraction expansion due to material differences in the case of using a different kind of barebone.
