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 best used as an internal partition in your home, 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 comprehensive 10-year manufacturer's warranty (terms & conditions apply). We also offer a complimentary aftercare service for your Cero I sliding doors, whereby we visit your home one year after installation to check that your doors are working as they should.
