Insulation structure of curtain wall with improved heat insulation property

摘要

The present invention relates to a curtain wall with improved thermal insulation performance. The present invention provides an inner frame 10 to which a window frame 60 is fixed and located on the indoor side, an outer frame 20 fixed to the front of the inner frame 10, and the inner frame 10 and the outer frame Including a fixing means for fixing the heat insulating connecting member 30 coupled to the inner frame 10 and the outer frame 20 and the insulating connecting member 30 coupled to the 20, to provide improved heat insulation and durability to provide wind pressure resistance Along with the performance, the sound insulation is improved.
