(1) The performance of the building decoration curtain wall includes wind pressure deformation performance, rainwater leakage performance, air permeability, plane deformation performance, thermal insulation performance, sound insulation performance, and impact resistance. The performance of the building decoration curtain wall is related to the geographical location, climate conditions, height, shape and surrounding environment. In coastal or typhoon areas, the wind pressure deformation performance and rainwater leakage performance of the curtain wall in the windsha area are high, while the wind pressure deformation performance and breathability of the curtain wall are high. For hot and cold areas, the performance of decorative curtain walls has good thermal insulation performance.
(2) Under the standard value of the wind load, the relative deflection of aluminum alloy profile should not be greater than the relative deflection of L180 (L is the span between the main column or the main beam), and the relative deflection of the steel profile should not be Greater than 1 300, absolute deflection should not be greater than 15mm.

(3) In addition to the standard value of the wind load, in addition to the gust coefficient, rainwater leakage should not be occurred, and the rainwater leakage of the building decorative curtain wall should meet the design requirements.
(4) When there is heat performance requirements, the breathability of the curtain wall should meet the design requirements.
(5) The plane deformation performance of the curtain wall can be represented by the relative displacement value between the building floor. The curtain wall should not be damaged within the relatively displacement range allowed by the design permit. The design should be carried out three times that of the elastic bit of elastic bit of the main structure layer.
What is the performance of the building decoration curtain wall: the heat transfer coefficient of the curtain wall should be designed and calculated according to the relevant specifications. Under the design environment, condensation should not be occurred in the curtain wall. For buildings with high heat performance requirements, on -site thermal performance tests can be conducted. The thermal heat transfer coefficient grading index K shall meet the requirements of Table 17. The shade coefficient of the glass curtain wall should meet the requirements: the design and calculation of the shade coefficient according to the relevant specifications. Glass curtain wall shade coefficient grading index SC should meet the requirements of Table 18. The thermal performance of an open building curtain wall should meet the design requirements.
