Building curtain wall

Test items

 

Air tightness, water tightness, wind pressure resistance, planar deformation performance, insulation performance, sound insulation performance, impact resistance, indicator testing, performance testing, non-standard tests, industrial problem diagnosis

Appearance inspection: Check the flatness, color and surface treatment of the exterior wall, the quality of the glass curtain wall, as well as the curtain wall sealing strips, fixing parts and other accessories. Discover problems such as damage, cracking and detachment of the curtain wall.

Structural safety assessment: Through the evaluation of the materials, construction and manufacturing processes of the curtain wall, determine whether the bearing capacity and stability of the curtain wall meet the design requirements, and pay attention to the connection method between the curtain wall and the building structure and the actual usage situation.

Fire resistance performance testing: Evaluate the combustion performance, flame retardant performance of the curtain wall materials and the fire spread performance between the curtain wall and the surrounding buildings to ensure that the curtain wall can effectively resist the spread of fire.

Lightning protection performance testing: Check whether the lightning protection devices of the curtain wall meet the design requirements, whether the grounding resistance meets the regulations, and whether the vertical lightning protection path is unobstructed.
