Almost limitless window designs are possible, including the use of angles, arches and circular shapes.

The windows and doors are all manufactured to exacting quality standards, and we support this promise with a 10-year manufacturer’s warranty.

Our PVCu windows and doors are reinforced with galvanized steel and have a double weather seal, making them most suitable for use in tall buildings such as condominiums, apartments and offices.

Sliding Doors and Windows

We offer high performance systems that have multilevel seals against rain, wind and noise. Multi Chamber profiles. Complete with choices of high specification locks and hardware. Integral fly screens are also available.

Single, Double, Triple and parallel Sliding Doors can provide an opening up to 16M wide.

Casement Windows and Doors

All our frames are reinforced with galvanized steel, forming a core that provides excellent strength and rigidity. All locks and hinges are fixed into this steel sub-frame.

The 45-degree slope on slim look frames helps rainwater to drain rapidly away from the window’s surface during the heaviest downpours.

A double-seal EPDM (modified rubber) gasket keeps the windows perfectly watertight.

We offer a number of hardware options, including as standard multi-point security locks all to European standards.

Sliding windows are also available, which, unlike most Aluminum frames, can be fitted with Insulating Glass Units.
