Essential Casement
An outward-opening casement on the Essential platform, in two frame depths. 95mm is the standard depth — nothing swings into the room, which frees up furniture placement and usable floor area in compact plans; a hydraulic damper is available to stop the leaf being caught by wind, and retractable screens roll out of sight when not in use. 70mm is the shallow-frame companion, matching the Essential 70mm tilt & turn for openings that need a simple outward-swinging vent without the deeper jamb.
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.
Full RAL range on request; the twelve most-ordered colours are listed. Powder coat or anodised.
No price is shown because every unit is made to order. You will get a written quote for exactly this configuration.
Overview
An outward-opening push-out casement on the Essential platform, in two frame depths chosen as a configurator option. Because the sash swings out, nothing at all projects into the room — the catalogue makes the point directly, that this frees up furniture placement and usable floor area, which is what matters in a compact hotel room or apartment plan where an inward sash would sterilise a strip of floor along the wall.
95mm is the standard depth, matched to the 95mm tilt & turn and swing door for one elevation’s worth of consistent sightline; a hydraulic damper is available to stop the leaf being caught by wind, and retractable roll screens run on the same damping system so they return at an even rate and roll out of sight when not in use. 70mm is the shallow-frame companion, matched to the 70mm tilt & turn, and brings the Technoform nylon thermal break and Siegenia hardware in place of the 95mm depth’s volume-tier set — specify it where the wall depth is limited or the acoustic and thermal package matters more than production cost.
Construction is shared across both depths: T66 aviation-grade aluminium alloy, penetration-welded frame and sash corners, and multi-chamber PA66 nylon barrier strips through the section. Finishing is an AkzoNobel powder coat from the same nineteen-colour extruded-aluminium palette. Glazing is dual pane with low-e and argon as standard or triple pane where the pocket allows, tempered as standard. Frame options cover new build and replacement: a 1/2" nailing flange (1 3/8" optional), a flush-fin frame for stucco replacement, a no-flange drill-through frame, or galvanised metal straps for installing anywhere within the wall cavity.

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.
How large combinations are joined →Where a window has to serve as an escape route, three dimensions matter at once — clear width, clear height and clear area — and meeting two of the three is not enough.
Awning units and single tilt-only units cannot be used as escape windows at all, because the sash itself obstructs the opening. If an opening is designated for egress, it needs an operator that swings or turns clear.
The figures above are the manufacturer’s minimums for the product and are NOT a code citation. US residential egress under IRC R310 is a different set of numbers — 5.7 sq ft net clear opening, 24" minimum height, 20" minimum width — and your jurisdiction’s adopted code governs, not this page. Send us the opening schedule and the address and we will confirm in writing which units satisfy the code that applies to you.

Options
Finishes
Powder-coat finishes to the standard RAL card, plus anodized options. Wood interiors are available in several species and interior finishes.
Glazing
- Double- or triple-pane insulated glass
- Low-E1 / Low-E2 / Low-E3 coatings
- Argon fill
- Tempered and laminated build-ups
- Custom interlayer colours and patterns
Bay and bow assemblies
Both are built from the units on this page rather than being separate products, so the finish, glazing and hardware you specify here carry straight through into the assembly.
Units set at an angle to project out from the wall, which turns a flat elevation into a seat, a deeper sill or a reading corner. Built from 3 to 6 casement or tilt-turn units, each of which can be fixed or operating — so you can put opening lights only where you need ventilation.
Four or more units connected in a gentle outward curve rather than faceted angles. Reads softer than a bay and pulls light in from a wider arc. Available with casement, tilt-turn or picture windows.
Size and performance figures on this page are for the individual units. The structural limits of a specific assembly — how wide, how many lights, what header is needed above it — are confirmed by the factory against your opening, and we get that in writing before it is quoted.
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
- Standard configurations, such as a 70-series double-glazed unit: 18 days in the factory from order. This is production time and does not include shipping.
- Special configurations: 3–5 weeks in production, also from order.
- Ocean freight: about 35 days to the U.S. West Coast, about 45 days to the East Coast.
- Schedules are confirmed in writing at order. We build to your project timeline.
