Sliding windows — aluminium systems

For wide openings where a swinging sash has nowhere to go — panels move sideways on rollers and never claim floor space.

A sliding window trades the casement’s compression seal for width. Nothing swings into the room, so it suits kitchens over counters, walkways, and any wall where furniture sits close.

All four systems are thermally broken with concealed drainage. The differences are in the running gear: track count, roller load, and NW-04’s lifting mechanism, which carries 120 kg a sash and locks it down when closed.

Choose this when

Wide openings — three-track systems put half the wall on rollers
Rooms where a swinging sash would collide with furniture or people
Balconies and service areas that need ventilation without claiming space

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 multi-track sliding system cut through the meeting stiles — **Track configuration**6 tracks narrowEach panel gets its own track. Track count is what sets how wide the opening goes and how much of it clears.

The hardware rebate of a window frame, hinges and locking points visible — **Hardware in the rebate**Hinges, locking points and the friction stay sit inside the rebate, out of sight and out of the weather.

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.

04

Performance

Rated by the supplier for buildings within six floors, rising to within fifteen floors on the heavier sections. Roughly 50% ventilation area without claiming interior space.

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