Built to keep weather out and comfort in.
Every window in the collection shares the same engineering standards, regardless of style or size.
Triple-seal weatherproofing
A three-channel, equal-pressure sealing design — a patented national utility model — keeps wind-driven rain and drafts out.
6063-T5 aluminum frames
Every profile is powder-coated 6063-T5 aluminum for corrosion resistance, rigidity, and a lasting finish.
Branded German & import hardware
Locking and hinge hardware from Wehag (Germany), Hopo, Caldwell, and other trusted manufacturers, model by model.
