457 Integrated Cornerless Folding Window

Designed to complement our high-quality Integrated Cornerless Folding Door, the Centor 457 Integrated Folding Window perfectly frames any view, and features the same thermally-improved aluminium construction.

The Cornerless Folding Window can have 2, 3, 4 or 5 panels on each side, in ‘odd-odd’ configurations (e.g. 3 doors on the left, 5 doors on the right) or ‘odd-even’ configurations (e.g. 3 doors on the left, 4 doors on the right).

For inside-outside living without the compromises, the Centor 457 Integrated Cornerless Folding Door incorporates a choice of either built-in screens or blinds to control insects, sunlight and privacy. Our shades also enhance the thermal properties of the window, with independent tests showing that the blackout shade improves the U-value by 17% when drawn across the opening.

  • No corner post to interrupt views or access. 
  • Aluminium exterior available in a range of popular colours or specify your preference.
  • Engineered to last a lifetime – extrusions are painted after cutting and machining to ensure all surfaces are coated. 
  • Hidden hardware including Access AutoLatch™, AutoLatch™ and concealed hinge.
  • Integrated insect screens and blinds are accessible for service or replacement. 
  • Screen box facings are available to enable simple installation into an existing opening.

Features
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
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
On the exterior, a slimline vertical pull-handle allows panels to be opened with ease.
AutoLatch™

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

Concealed hinge

The concealed hinge on the Centor 255 Integrated Folding Window is hidden from sight within the edge of the window. Not only does it look great, but it also makes the window tamper-proof for additional security.

Integrated screens and blinds

Built into the window frame, our innovative integrated insect screens and blinds 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.

Centor screens for Integrated Windows are built into the window frame
Screens
Choose between two mesh types to keep even the smallest insects out – like homeowner Deb in Derbyshire: “Although there are a lot of midges near the moorland, we really didn’t expect to need it very much. It’s been so useful though – even in England!”
Centor shades for Integrated Windows retract from sight into the window frame when not in use
Blinds
Available in two patterns and a range of colours, our blinds retract from sight when not is use – which appealed to Gillian in County Durham: “I didn’t want any curtains in my house, but I wanted the capability to occasionally block the light out and to close the windows off at night.”
