A. Technical

Structural calculations are done to ensure that proposed sections are capable of withstanding the wind pressure and other loads.

Glass is well supported and held properly.

Properly designed gaskets (EPDM or Neoprene) is used which can withstand vibration due to heavy winds and expansions due to temperature.

Fixing of the frame to structure is so designed which ensures the expansion and contraction in building structure due to temperature variation.

Structural sealant is properly used as per manufacture specification.

Horizontal to vertical joints should be through well-designed concealed cleats.

B. Water Proofing
Gaps are sealed properly

Provision is made in the frame for drainage of water that leaks in. PRESSURE EQUALISED CURTAIN WALL/SG frame design should be adopted.

C. Aesthetic Appearance
Finished work should appear as per client’s design from inside and outside.

D. Functional
1. Vision and spandrel panels should be correctly separated
2. Framework and clamping system should suit the interior work inside
