403 Integrated French Door

Thanks to concealed hardware, the Centor 403 Integrated French Door perfectly frames any view, with equal-sized panels and simple lines. It’s constructed from thermally-improved aluminium. 

For inside-outside living without the compromises, the 403 Integrated French Door incorporates built-in screens and shades to control insects, sunlight and privacy. Our shades also enhance the thermal properties of the door, with independent tests showing that the blackout shade improves the U-value by 17% when drawn across the opening.

  • Aluminium available in standard or custom RAL colours.
  • Engineered to last a lifetime – extrusions are painted after cutting and machining to ensure all surfaces are coated. 
  • Hidden hardware including Access AutoLatch™ and AutoLatch™.
  • Integrated insect screens and shades are accessible for service or replacement. 
  • Screen box facings are available to enable simple installation into an existing opening.

Access AutoLatch™

Centor’s latest locking innovation, the Access AutoLatch™, replaces the traditional entrance handle with a concealed version that’s hidden from view in the door stile.

Interior of the Access AutoLatch
The lever is simply lifted to open the doors from the inside. A ‘signifier’ on the face of the panel hints at the lever’s location.
Exterior handle
On the exterior, a slimline vertical pull-handle allows panels to be opened with ease.

The Centor AutoLatch™ is used to close and secure intermediate panels in one movement, with one hand. It is available keyed or non-keyed.

Integrated screens and shades

Built into the door frame, our innovative integrated insect screens and shades are a world-first offering. They allow homeowners to enjoy inside-outside living without the compromises traditionally associated with large openings – insects, glare and loss of privacy.

Screens for Centor Integrated Doors are available in two mesh types to keep insects out while enjoying fresh air
Choose between two mesh types to keep insects out while enjoying fresh air – like Heather: “The insect screen is particularly great. Some mornings, I’ll just open two panels of the door, slide the screen across and the whole house benefits from a free flow of fresh air. It’s not intrusive at all.”
Shades for Integrated Doors are available in two patterns and a range of colours
Available in two patterns and a range of colours, our light-filtering and blackout shades retract from sight when not is use – which really appealed to Paul in Surrey: “They’re neatly concealed in the end reveals... and when they’re not being used you don’t know they are there. It’s very clever design.”
Weather tests

The following performance levels were achieved when tested in accordance with BS EN 14351-1:2006.

Air permeability
Class 3
Water tightness
Class 7A
Resistance to wind load
Class A3

The following thermal performance results were achieved in third party testing:

Double glazed: U = 1.4w/m2k
Triple glazed: U = 1.2w/m2k

Additionally, where blackout shades are fitted these values are improved by a further 0.2w/m2k.
