Unexposed Insulation Structure of Steel Curtain Wall

The present invention relates to a non-exposed coupling structure of a steel curtain wall, and more particularly, to a non-exposed insulating bond structure of a steel curtain wall that improves the adhesion and heat insulating performance of the neighboring curtain wall.

In general, the curtain wall is used for the exterior wall construction of modern buildings and refers to the outer wall that merely serves as a partition and does not support a load. The load of the building is supported by the pillars and the visible frames. For this reason, curtain walls are also called non-bearing walls, curtain walls, or partition walls.

As the wall material, metal plates, glass, blocks, and precast concrete are used. Curtain walls are often used in high-rise or high-rise buildings, where light materials are used to reduce the load. In recent years, multilayer glass is widely used as a curtain wall because of its properties, namely transparency, openness, reflectivity, and relatively light weight.
