Options.
Everything you can tick beside a Vistaza window, what each one is, which series and types take it, and the one number that decides it. Options are ordered with the window, not added to a finished frame.
Insect screens.
A screen on the outside of the opening sash, fitted and taken off from inside the room.
4-inch safety limiters.
A steel limit stop in the sash that holds an operable window at four inches. Approved by the New York City Department of Health, and stamped. It cannot be released by hand: it takes a special tool, which stays with the building's staff.
Trickle vents.
A slot through the head of the frame with a cover that closes from inside, so a room gets outside air while the window stays shut and locked.
Grilles between the glass.
A single bar sealed inside the insulating unit, so the pattern is there and both glass faces stay flat.
Simulated divided lites.
Bars bonded to both glass faces with a matching bar inside the unit, so the divide reads as a real one from inside, from outside and at an angle.
Exterior trims.
A uPVC profile that closes the joint between the frame and the finished facade. It is cut and mitered at 45 degrees at our plant, then packed, labeled by opening and loaded with the windows, so the pieces arrive ready to screw on.
Nailing fin (Vi5).
A flange around the outside edge of the Vi5 frame: the installer fastens through it, and it ties into the flashing and the water-resistant barrier.
PTAC louvers.
A fixed-blade aluminum louver glazed into the window frame in place of glass, so the air transfer sits on the same frame line as the glass.
ADA door sill.
A low, flat threshold for a Vi6 in-swing terrace door, with a seal that lifts to meet the door as it closes so the door never drags on the sill.
ViBird bird-safe glass.
Insulated glass carrying a pattern birds can see, in the same window, the same frame and the same opening.
Spandrel glass.
Opaque, ceramic-painted glass in the RAL color you choose, built as an insulating unit to the same thickness as the windows beside it — for slab edges, mechanical zones and blank panels.
Ticked on the schedule. Drawn on the shop drawings.
Every option here is a line on the estimate at project level and again per window type, so the schedule says which types get it. It is then drawn on the shop drawings — on the head detail, the jamb, the sill or the elevation — and approved with the window rather than bolted on afterwards.
One thing is standard. The rest is by request.
The four-inch safety limiter comes on every operable window. Everything else here is by request. Say which openings get what on the schedule and it is priced as its own line. Several of these are machined or built into the frame at the factory, so the decision has to be made before the window is made.
