250 Integrated Fixed-lite

Connect to the beautiful world with the Centor 250 Fixed-lite window. The frameless design offers large expanses of fixed glass, with built-in shades to control glare and provide privacy. Like the fixed panel on the Centor 211 Integrated Sliding Door, the sill meets flush with the glazing for an unobstructed view to the outside.

Pair the 250 Integrated Fixed-lite alongside Centor Integrated Doors for a seamless aesthetic. 

For inside-outside living without the compromises, the Centor 205 Integrated Fixed-lite incorporates built-in shades to control sunlight and provide privacy. Our shades also enhance the thermal properties of the window, with independent tests showing that the blackout shade improves the U-factor by 17% when drawn across the opening.

Integrated shades

Built into the window frame, our innovative, fully retractable shades are a world-first offering. They allow homeowners to enjoy inside-outside living without the compromises traditionally associated with large openings, including glare and loss of privacy.

Available in three patterns and a range of colours, our light-filtering and block-out shades retract from sight when not is use – which really 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.”
