1. Rain Storm

• Durable water-tightness performance due to elimination of critical seal by design.
• Durable water-tightness performance due to large tolerances to various structural movements without sealant line stresses.

2. Wind Load

• Long term safety against fastener failure due to direct force transfer into mullion by panel engagement without reaction force on fastener.
• Additional safety against structural failure due to automatic recoverable pressure venting mechanism.

3. Thermal Load

• No system functional degradation due to free thermal movement at vertical and horizontal panel joints in all direction.
• No thermally induced noise due to the elimination of member interference caused by thermal bow.
• Cooling effect in summer due to natural air venting of the inter-connected Airloops.
• Added insulation in winter due to the near still air in the Airloops.

4. Seismic Load

• Highest tolerance for inter-floor story drift due to the allowance of automatic recoverable panel drifts.

5. Floor Live Load

• Tolerable for any amount of spandrel beam deflection without causing any functional problem due to the ability to control the panel joint movement to a small amount (e.g. 6 mm) while allowing any large floor deflection (e.g. 30 mm).

6. Maintenance

• Least window/wall washing requirement due to no exposed caulking design.
• Elimination of water stain problem due to instantaneous and hidden drainage design.
• Various design options for easy replacement of facing materials.
