Two different door handle choices operate the advanced multi-point door lock and high security cylinder. Overall, the entire product is designed, made and fitted to provide you and your family with a safe, secure and reliable product for many years to come.

Energy Efficiency

Latest generation polyamide thermal breaks separate the aluminium profiles, creating a thermal bridge. As a result, cold transfer to the inside is minimal. The insulated glass units work with the thermally insulated frames to prevent heat escaping and maximising solar gain. So whether you choose the slimline OS-44 or the classic Origin OS-77, you get the same great thermal performance. Doors have a U-Value down to 1.2 for triple glazing and 1.8 for double glazing. An ideal product to offer style, security and energy saving in your home. They exceed the requirements of current Building Regulations too.

Therefore, the Origin OS-77 sliding door helps save money on your energy bills whether they replace your old doors or in a newly-built extension.
