Casement windows — aluminium systems

The deepest family in the range — thirteen systems from a 65 mm slim frame to a 122 mm section built for high floors and strong wind.

A casement is the working window: it swings on hinges, seals by compression, and closes against the frame like a door. That compression is why a well-made casement is the tightest-sealing opening window there is — the harder the wind pushes, the harder the sash presses onto its gasket.

The range splits on three decisions. Thermal break or not — only NC-01 goes without one. Where the water drains — concealed from NC-04 up. And how much the hardware carries, from 50 to 70 kg a sash.

Choose this when

Bedrooms and living spaces where sealing against rain and noise matters most
Openings that face weather — the compression seal works with the wind, not against it
Where you want the window to disappear: slim GE-series frames run down to 65 mm

03

Inside the frame

The same system, cut open. This is what sits behind the plaster once the trim goes on — and it is where a window succeeds or fails.

A frame corner cut open to show the glue-injected, angle-formed joint — **The corner**Corners are formed with injected glue and crimping rather than screws alone, which is what keeps a frame square and sealed once it is under wind load.

The thermal breakThose blue strips are PA66 polyamide, threaded through the profile to hold the inner and outer halves apart so heat and condensation cannot bridge the metal.

A window frame cut open in driving rain, showing the concealed drainage chamber in the sill — **The hidden drainage path**Rain driven at the frame collects inside the sill chamber and leaves through a concealed slot, instead of running down the face of the window.

A narrow-frame section cut through the sash and outer frame — **The narrow sightline**How little frame you can see is a function of how much structure sits behind it. This is the section that lets the sightline run slim without losing rigidity.

04

Performance

The supplier rates these by building height and opening size rather than a single number: the entry system for buildings within three floors and low wind pressure; the mid range for buildings within six floors with openings of 3–5 m²; the heavy end for high buildings needing strong wind resistance, with French windows within 10 m².

What a specific opening achieves depends on its size, exposure and installation. That is why we assess the opening before we specify the system.
