The single-glazed glass panels of the Cero I can reach up to 4 metres high and 3 metres wide.

The Cero I is the only sliding door in the range that is single glazed and not thermally insulated. It is therefore ideal for spaces prioritising aesthetic elegance and visual appeal over thermal efficiency. It would be a great choice for a summer house or garden room, or as a room divider or partition glass sliding wall in your home.

The visible part of a window or glass door frame when viewed straight on is called a sightline. Slim sightlines are generally preferable because they allow a greater amount of natural light into your home. They also offer better views of your outdoor space.

The Cero I comes with a single ten year warranty because the whole system is designed, made, delivered and installed by us. This gives you peace of mind about who to contact should any issues arise. We also offer a complimentary aftercare service one year after installation of your Cero sliding doors, where we visit your home to check that your doors are working as they should.
