Professional specifications, installation guide & design solutions
A fixed window does not open. It is a glazed frame, or glass set directly into a wall system, chosen where light and view matter and ventilation comes from elsewhere. Fixed lites carry the biggest glass on a building, cost less than operable units of the same size, seal better than anything that moves, and are the picture windows, transoms, sidelites and shaped units that make up most of a facade.
A fixed window is a glazed frame that does not open. It carries the largest glass on a facade, costs less than an operable unit of the same size and seals better than anything that moves. We supply fixed lites in every system we fabricate — Reynaers, Cortizo, Alutech, Everest, Crystal — and in the Pella, Andersen and Marvin lines, as picture windows, transoms, sidelites, shaped units and the fixed panels of window walls and curtain wall inserts.
We carry multiple premium manufacturers for fixed-window windows including:
Each brand offers distinct advantages in performance, design, and price point. We can help you choose the perfect fit for your project.
Proper installation is critical for optimal performance. Our installation team provides:
Installation includes sealing and flashing the perimeter of the opening, because a window is only as watertight as the junction between it and the building. Where an opening needs more than that — a failed sill, damaged masonry, a detail that was wrong to begin with — see waterproofing.
A fixed window has no sash, no hinges, no operator and no lock. Everything that wears out on a window is absent, and everything that leaks air is absent with it.
That gives three real advantages. It is the most airtight window available, because the glass is sealed directly into the frame with no opening joint to seal. It gives the most glass for a given opening, since there is no sash frame inside the outer frame taking up sightline. And nothing fails — no balance to replace, no hinge to sag, no operator to strip.
It is also the cheapest window per square foot, which surprises people who assume a large picture window is expensive. The glass is the cost; the mechanism is what you are not paying for.
Ventilation, escape and cleaning.
Ventilation is a code matter, not a preference. New York calculates habitable-room ventilation on the area that actually opens, so a room glazed entirely with fixed lites may not comply regardless of how much glass it has. This is the single most common problem with fixed glazing and it is entirely avoidable at design stage.
Escape. A fixed window cannot serve as a required means of egress. In a bedroom that matters.
Cleaning. The outer face has to be reached from outside. At ground level that is trivial; on a fourth floor it means equipment.
Most well-designed glazing pairs a large fixed lite with a smaller operable one. A picture window with casements either side; a fixed centre with an awning vent below; a fixed panel with a tilt-and-turn beside it.
You get the glass area and the sightlines from the fixed portion and the ventilation, escape and cleaning access from the operable one — and you only pay for mechanism where it is needed.
Fixed glazing can be very large, but the limit is weight and handling rather than the frame. Thickness rises with area, weight rises with thickness, and at some point the unit cannot be carried up a stair, through a building, or lifted into place without equipment. On a replacement job in an existing building, access is frequently the binding constraint rather than anything structural.
Large fixed lites at height should also be laminated, so that a failure does not put glass down onto whatever is below.
These describe the kind of work each area brings rather than any specific client project.
View elevations — Deal, Long Branch, Todt Hill, Riverdale, the waterfront. Where the view is the point, fixed glazing gives the largest uninterrupted glass and the slenderest sightlines. Paired with operable units elsewhere in the room for ventilation.
Stairwells, landings and double-height space — townhouses citywide. Openings nobody can reach to operate, where a fixed lite with a high-level awning or electric operator is the sensible arrangement.
Commercial and storefront — Flatbush, Third Avenue, Astoria. Retail frontage is largely fixed glazing by nature, with ventilation handled mechanically.
Transoms and sidelites — brownstone entrances, apartment lobbies. Fixed lites above and beside doors. Safety glazing is required in panels adjacent to a door, so these are tempered or laminated by code.
Tell us the opening size, what the room is used for, and how the glass would get to the opening. We supply and install across Manhattan, Brooklyn, Queens, the Bronx and Staten Island, and throughout Northern New Jersey, the Jersey Shore, Philadelphia and the Lehigh Valley.
A window that does not open: a glazed frame or glass set directly into a wall. Used for light, view and large glass where ventilation comes from another window.
Yes, typically 30–50% less for the same size, because there is no sash, hardware or weatherstripping; the glass is the main cost.
Larger than any operable unit: limited by glass manufacturing sizes, wind load and handling, not by hardware. Lites of 8 by 10 feet and more are routine with structural mullions.
No. Every bedroom needs an operable egress window; fixed lites are paired with a casement, tilt-and-turn or double-hung that meets the egress opening size.
Only in hazardous locations: within 24 inches of a door, less than 18 inches from the floor with a large lite, in stairs and bathrooms. Elsewhere annealed or heat-strengthened glass is used.
