Spacer Structure for Multi-Layer Glass

The present invention relates to a multilayer glass provided with a thermal cross-linking spacer, more specifically, a thermal cross-linking that combines a plurality of glass laminated in a predetermined interval can be excellent in mechanical strength and at the same time maximize the thermal insulation as compared to the conventional It is related with the spacer for multilayer glass which improved the structure of a spacer.

Multi-layered glass is a combination of two or more pieces of glass at predetermined intervals, and a spacer is used to bond while maintaining the gap between the glass. The spacer is generally located along the edge of the glass between the two sheets of glass.

In general, since the laminated glass has a space formed between the inner and outer glass, not only does it minimize the loss of room energy compared to the single glass, but the surface temperature of the inner glass decreases relatively less even though the outer temperature is lowered. Dew condensation is suppressed. In addition, it is excellent in sound insulation performance can effectively block the transmission of noise between the indoor and outdoor.

Although such laminated glass is relatively expensive, its use is gradually increasing due to the enhancement of the living environment and the development of its manufacturing technology due to the improvement of economic power.
