Flush glazed, frameless glass system with aluminium. Ultra modern contemporary appearance. Clean lines and smooth appearance.

Thermally efficient, triple glazed, argon gas filled, unique architectural designed system incorporates open in or open out, stacking left or stacking right, glazed in or glazed out configurations, with maximum security and integrity with no compromises.

Powder coated thermally broken aluminium frames for structural stability and strength blended with a unique designed glass retaining system ensuring that no glazing beads are required and that the structural integrity of the glass panels remain intact in all opening situations.

The design of the system also ensures the glazing chambers are fully ventilated thus ensuring longevity of the triple glazed units.

All systems can be customized with a choice of RAL colours, hardware, thresholds and glazing options. The system can be manufactured in a short amount of time using our standard colours, black (RAL 9005 matt), white (RAL 9016 satin) and grey (RAL 7016 matt). Or you can also choose from hundreds of other colours to suit your taste.
