Maintenance and Diagnostics
Regular maintenance of glass curtain wall should be carried out with cleaning agents that will not affect the integrity or durability of the sealants or materials. Periodic inspections should also be made from inside the building during rainy days so that small leaks can located and repaired immediately. Faulty components should also be replaced before they allow water to penetrate.
Diagnostics of Defect
Visual Inspection
Visual inspection of the external and internal façade should be done. The condition of the sealant should be assessed. Internally, the sealing of mullion to transom, continuity of joint and quality of the air seal should be determined.
Windows should be checked that they can closed easily and that the air seal gasket is compressible.
Watertightness test
Site test such as Watertightness Test is conducted to determine if the windows leak, how they leak and how to avoid leakage in the future.
