CS 77 windows and doors

Comfort, security, structural integrity and style — this frame system excels in every aspect. It’s the epitome of high technologies. It’s our secret behind the most perfect operable windows, glazed doors and offset pivot doors.


Hi-Finity sliding doors

Just visualize an 8’ wide sliding panel with triple glazing and the least possible frames. Turn the handle 180 degrees — and the panel lifts up on Swiss bearing rollers providing frictionless operation. Turn the handle back, and the panel eases down from the weight of itself sealing perfectly in our winters.


CF 77 folding doors

Designed to hold the weight of the panels on the sill, this folding door system allows wider panels with maximum glass and reduced costs. The system can stack left or right, inside or outside, and can have an integrated door for easy in and out access.
