The Cero III's flush frames and ultra-slim 34mm profile sightline provides an amazing 98% daylight transparency, flooding your home with natural light and opening up panoramic views of the outdoors. And with equally impressive quality, movement and versatility of design, it is the epitome of premium, custom-made passive glazing.

Exceptional Energy Efficiency

These premium bespoke glass doors use high performance glazing and no less than three thermal breaks within the frame to help maintain the perfect temperature in your home.

Smooth Operator

Despite its huge size, the Cero III is incredibly easy to operate. Thanks to its superb, German engineered design and stainless steel carriages, rails and rollers, it glides smoothly and seamlessly along the track.

The Cero III sliding doors are easily moveable by hand but can be automated if preferred. Our preference would be that panels weighing over 400kg are motorised, but the choice is yours.
