UPVC Fixed Window
A fixed, non-operable UPVC window for openings that do not need ventilation — the picture window beside a door, the tall lite in a stairwell. UPVC gives up nothing to aluminum here: this line’s best certified U-factor (0.14) is the lowest of any system in the catalogue, aluminum included. Frame depth, maximum size, finish and glazing build-up are confirmed at quotation.
Configure your unit, then request a quote — we price it and reply, usually within one business day.
Every unit is made to the opening. Sizes confirmed at quotation.
Low-E1 / E2 / E3 coatings, laminated and tempered build-ups available. We recommend the coating for your climate zone.
No surcharge for any of these European hardware brands.
No price is shown because every unit is made to order. You will get a written quote for exactly this configuration.

Mounting and frame options
The frame type decides the rough-opening detail, the flashing and how much of the existing wall has to come out. Four are available; tell us the wall build-up and we will specify which one your opening needs.
The standard new-construction frame. The flange laps the sheathing so the unit sets and seals in one operation.
A 1 3/8" flange is available where the cladding build-up needs the extra reach.
Installs over an existing aluminum window frame, so the stucco exterior is left intact. No cutting back and repatching.
Available on selected window types — ask us which of your openings can take it before you price the stucco work.
For full removal, when the existing frame is rotten or damaged and has to come out entirely.
Sets into the existing rough opening, and arrives with the through-the-jamb holes pre-drilled and the screws supplied.
Straps fix to the frame, which lets the unit sit anywhere in the depth of the wall cavity rather than at a fixed setback.
Installs from the interior, and works for both new construction and replacement.
Full CAD details for any of these are available on request for your wall assembly.
Factory-joined combinations for large openings
Multi-unit combinations are joined in the factory and delivered as one assembly, so the joint is made under shop conditions instead of on a scaffold. The joining mullion is 1 1/8" (28 mm) wide and comes in three reinforcement grades, chosen by the height of the window it has to carry. The system is covered by a US patent.
| Suggested window height | Joint width |
|---|---|
| up to 9 ft | 1 1/8" (28 mm) |
| 9 to 11 ft | 1 1/8" (28 mm) |
| 11 to 13 ft | 1 1/8" (28 mm) |
Combinations arrive partly or fully assembled depending on size and shipping method. Tell us the opening and we will confirm which grade your height needs and how the unit will be split for transport, before you price the crane time.

NFRC certified performance
Certified figures from the NFRC Certified Products Directory — the source a U.S. building department will check. This window is certified separately as a fixed lite and as an operable lite, so both are shown: the operable sash carries the hardware and the operating joint, which costs a little thermal performance.

- Double- or triple-pane insulated glass

Exterior finish
The exterior is extruded aluminum cladding, which is why the finish schedule matters more here than the colour chart on a vinyl window: it is a powder coat on structural extrusion, not a surface tint.
19 finishes are available in total, including three pearlescent. Twelve are named here; ask us for the rest, or for a custom colour match.
Swatches are indicative only — reproduced from print, shown on your screen. Specify by RAL number, and ask us for a physical sample before you commit an elevation to a colour.
Lead Time
- 9–10 weeks total, door-to-door: production, customs clearance, duties and delivery to your jobsite — nothing left for you to arrange separately.
- Ocean freight and drayage are booked and tracked on your order, not quoted as a separate step afterward.
- Shop drawings and a confirmed production schedule are provided before deposit, so the 9–10 weeks starts from a real date.
- Schedules are confirmed in writing at order. We build to your project timeline.
