Large sliding glass panels give you unparalleled views

One of the most obvious benefits of our sliding doors is the sheer size of the glass panels. The doors can be up to 2,700mm wide, creating a wall of glass that floods your room with natural daylight and gives you fabulous panoramic views with minimal frame intrusions.

These wide doors also create a large opening. This provides exceptional ventilation during hot weather and easy access from your room to your outside area.

The doors are designed to slide smoothly and easily every time. They can be fitted with premium stainless steel rollers, or a lift-and-slide mechanism that lifts the door above the track for effortless, friction-free sliding.

Your questions, answered

What is a U-value?

The U-value of a product measures how effective its insulation properties are. The lower the U-value, the better the insulation. As a guide, a standard double-glazed window typically has a U-value of 1.8 W/m².

What is a thermal break?

A thermal break is a material with low thermal conductivity placed between conductive materials to reduce or prevent the flow of thermal energy.In our products, these thermal breaks include resin, silicone and styrofoam, which separate the conductive aluminium components to provide superb thermal insulation.
