Cero III FAQs

When sliding doors are opened, they move to one side and usually cover half of the aperture (50% of the opening) if they are on a twin track, or one third of it if on a triple track, leaving 66% of the aperture open.

There is, however, one way to achieve a 100% opening with sliding glass doors - and that's by creating a pocket door. This is when a cavity is designed in the wall, into which the doors can slide when open. This hides them away completely, leaving a 100% opening of the aperture.

While we don't have the Cero III sliding doors on display at our Leeds premises, we do have a large Cero II sliding door on display which embodies many of the features of the Cero III (the key difference between the two is that the Cero II is double glazed and the Cero III is triple glazed). And if you contact us to book a visit, we will ensure one of our glazing specialists is there to show you around the display and answer any questions you may have.

The Cero III comes with a comprehensive 10-year manufacturer's warranty (terms & conditions apply). We also offer a complimentary aftercare service for your Cero III sliding doors, whereby we visit your home one year after installation to check that your doors are working as they should.
