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 immediately before the defect gets worsened.
Diagnostics of Defect
Visual Inspection
Visual assessment of the curtain wall during rainy days can reveal the location where water will seep in.
Thermography
Thermography can also be used to investigate the path of water penetration.
Fibrescope
The building structure can also be checked for movement to reveal areas that are stressed and causing cracks or gaps to appear. This can be done by inserting probes of the Fiberscope to inspect connecting condition behind external cladding wall of a building.
Elastic recovery meter
In the case of sealant failure, an Elastic Recovery Meter can be used to check for its effectiveness.
