The SL60, SL70
and WA67, with their very high air, water
and structural performances, are well suited for high rises.In European life cycle
testing (more exacting than AAMA 910-93, with 10,000 cycles instead of 2,500 cycles),
the inward opening SL60 and
SL70 had no damage to fasteners, hardware parts, or any other damage that
caused the system to be inoperable, and air infiltration and water resistance tests
did not exceed Gateway Performance Requirements for Hinged Glass Door, HGD-R40 and
HGD-C55, respectively.
