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. European oak interior in finished and unfinished options. Aluminium exterior available in a range of 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™, AutoLatch™ and concealed hinge. Integrated insect screens and shades are accessible for service or replacement. Screen box facings are available to enable simple installation into an existing opening. Double or triple glazing available. 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.
