Insulation system of curtain wall improved performance of exterior thermal insulation

摘要

The present invention relates to a technique for improving thermal efficiency by using an insulating material in a stick system curtain wall. A polyamide, hard polyurethane, or vacuum insulating material is formed outside a curtain wall member, and thus thermal efficiency can be significantly improved as compared with insulating material formation in the middle of the existing curtain wall member. The present invention is to improve the thermal efficiency of a curtain wall by using a polyamide, hard polyurethane, or vacuum insulating material outside a curtain wall in a stick system curtain wall. The polyamide, hard polyurethane foam, or vacuum insulating material having excellent insulation performance is inserted into the outside end of the curtain wall member and the curtain wall member is formed as a result. Accordingly, insulation performance is more excellent as compared with the existing technique for polyamide and polyurethane formation in the middle of the curtain wall member and the product productivity of the curtain wall system can be improved.
