The Technal GXi sliding window and balcony door offers.

  • Contemporary detailing
  • Outstanding weather resistance
  • Concealed fixings
  • Robust, unobtrusive closing tracks
  • Ease of operation
  • Enhanced thermal performance


Clean, narrow sight lines.  41mm sight lines maximise natural light and provide an attractive, modern finish.

Thermal efficiency.  A 9mm flush polyamide thermal break provides efficient performance to meet the latest Building Regulations.

Profile options.  Profiles can be flat-faced for a crisp appearance, or curved to add a more distinctive and stylish accent to the external treatment.

Choice of configurations.  Options range from a simple two-leaf bi-parting system, to a multi-panel sliding patio door or window on two tracks.

Ease of operation.  Robust frames, durable hardware, a quality track and roller system and structural accuracy combine to ensure low maintenance, superior reliability and a smooth sliding operation, even with the largest leaf sizes.

Range of sizes.  The window or door can be supplied in a choice of sizes to suit individual project requirements and separate slider tracks in aluminium, polyamide or stainless steel are available to carry varied leaf configurations.

Glazing options.  GXi can accommodate 20 to 26mm glazed units.

Roller options.  Rollers can be standard or adjustable and are double to support the loadings of larger glazed units. The double roller can be replaced quickly and easily without dismantling the leaf or frame.

Full system compatibility.  GXi uses a 52mm module, which is fully compatible with Technal’s FXi52 casement window, to allow composite configurations to be created.  The system can also be inserted into MX curtain walling, making it ideal for penthouse situations, or integrated into Technal’s MODAL low-rise framing system.

Concealed fixings.  Mountings and fixings are concealed and there are matching end caps, plugs and seals for high quality finish.

Concealed drainage.  Special profiles can be supplied to conceal drainage and remove the need for unsightly caps.  The system can also be face drained through the cill.

Long-term durability.  The leaves are square cut and silicone sealed, and the stiles are bolted into the rails for lasting performance.

Choice of hardware.  A range of hardware and accessory options is available, including a half-moon semi-automatic handle, and a discrete finger-pull locking lever.

Design flexibility.  There is the option of single or dual colours.

A proven system.  GXi has been rigorously tested to 20,000 open/close cycles.
