High-rise Problem No. 1 : Large Story Drifts
due to Wind or Seismic.
- Conventional Solution : Increase the fixity
of the curtain wall frame corners (stiffening
and strengthening) to resist the distortions
due to the large story drifts. It is a stack
member design.
- TingWall Solution : Release the fixity of
the curtain wall frame corners by separating
panel frame from support frame and providing
engaged but sliding horizontal panel joints
such that the large story drifts can be absorbed
by stress-free panel drifts. It is a no stack
member design.
High-rise Problem No. 2 : Accumulation of
Cavity Water at Lower Floor.
- Conventional Solution : Provide segmented
outwardly draining horizontal gutters at every
other floor.
- TingWall Solution : Inter-connected Airloops
allow the high pressure air at the higher level
to enter the Airloops causing the over-pressurized
Airloops at the lower elevations to naturally
repel the water outwardly. This has been evidenced
by the completed Taiwan job in typhoon conditions.
High-rise Problem No. 3 : Water Stain on Exterior
Wall Surface.
- Conventional Solution : Use Open-Joint design
with Rain Screen Principle to eliminate the
water stain problem due to exposed caulking.
The water stain problem due to delayed gutter
drainage has not been solved.
- TingWall Solution : Use the combination of
Open-Joint design, instantaneous drainage mechanism,
and hidden drainage channels to completely eliminate
the water stain problem.
High-rise Problem No. 4 : Water-tightness
at Max. Inter-floor Deflection.
- Conventional Solution : Take the probability
risk with no solution.
- TingWall Solution : Patented design can limit
the curtain wall joint movement to ?quot; (6
mm) without impairing the water-tightness performance
while allowing large inter-floor deflection.
High-rise Problem No. 5 : Durability of Water-tightness
due to Various and Large Structural Movement Cycles.
- Conventional Solution : Use United System
to reduce the extent of Critical Seal execution
in the field. Water leakage possibilities due
to workmanship on Critical Seals or due to stress
fatigue of the Critical Seals have not been
solved. Passing a mock-up test can not address
the problem. The problem can only be answered
by the real building performance without knowing
in advance how long the water-tightness performance
will last.
- TingWall Solution : Completely eliminate Critical
Seal in the system by complete separation of
Air Seals from Water Seals. Long term water-tightness
performance can be assured. Wrong execution
of design details in the shop or field could
of course result in water leakage. However,
the problem will be noticed on the first rain
storm condition which is most likely to occur
before the completion of the curtain wall installation.
Once the problem is corrected (not in the sense
of repair), long term water-tightness performance
will be assured. This was verified during the
TingWall erection of E-Park 1 in Taiwan.
High-rise Problem No. 6 : Control of Completion
Deadline.
- Conventional Solution : Require early agreement
and coordination among all parties (curtain wall contractor, building owner,
architect, general contractor, other affected
subcontractors) to establish the detailed progressive
erection schedule. Delays due to unexpected
events such as damaged curtain wall units and
many possible field coordination problems often
become disputes on who is the responsible party.
There is no certain guarantee on the completion
date.
- TingWall Solution : The ability of leave-out/back-fill and simultaneous multiple point erection
due to non-directional erection method eliminates
the possibility of delay due to unexpected events.
This have been proved by all completed TingWall
projects (all completed ahead of the completion
deadline despite late start).
