255 Integrated Folding Window

Designed to complement our high-quality folding and French doors, the Centor 255 Integrated Folding Window perfectly frames any view, and features the same oak interior and thermally-improved aluminium construction.

For inside-outside living without the compromises, the 255 Integrated Folding Window 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.

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 shades

Built into the window 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.

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
Shades
Available in two patterns and a range of colours, our shades 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.”
