The Crystal Series 6000 has an outstanding AAMA rating of H-HC65 and features heavy-duty thermally broken 4-? frames, with custodial lock tilt-in sashes and 1 insulating glass units. To accommodate the needs of the building?s many senior tenants, lower window sashes were equipped with easy to operate Ultra Lift balances. The Crystal Series 8100 picture and 8200 project-out aluminum windows have great AAMA ratings of F-AW85 and AP-AW80, respectively. Both the 8100 and 8200 feature strong durable 2-? frames with 1 insulating glass units. All the windows were ordered with the optional face flange frames and interior snap trim with heavy-duty clip accessories to facilitate quick and complete replacement of the building?s original aluminum windows.

For energy efficiency all the windows were specified with special PPG Solarban 60 Low-E coating and Argon gas-filled insulating glass units. For aesthetics and durability the windows received an environmentally friendly bronze powder coat finish meeting the rigorous performance and durability specifications of AAMA 2604 national standards.
