261 XO Integrated Sliding Window

Complementing 211 Integrated Sliding Doors, the contemporary design of the 261 XO Integrated Sliding Window features a frameless fixed glass panel, ensuring the focus is always on the views outside. 

Available as a 2-panel configuration, our 261 Sliding Window is constructed from thermally-improved aluminum with a solid wood facing on the interior.

For inside-outside living without the compromises, the Centor 261 Integrated Sliding Window incorporates built-in screens and shades 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-factor by 17% when drawn across the opening.

  • Wood interior in five unfinished options or primed for painting.
  • Aluminum exterior in a range of standard or custom colors.
  • Engineered to last a lifetime – extrusions are painted after cutting and machining so all surfaces are coated, reducing the probability of filiform corrosion. 
  • Sliding panel glides with ultimate ease, thanks to impressive 3” (75mm) diameter, precision ground stainless steel wheels. 
  • Integrated insect screens and shades are accessible for service or replacement.
  • Double or triple glazing available.

Available in a Black or Stainless finish, the wood trim on the interior handle is matched to the window's frame finish. This handle acts a stop for the insect screen, ensuring that the mesh only covers the open area of the window.

Panel configurations

Specify the Centor 261 Integrated Sliding Window panels as symmetrical for a greater flow between inside and out, or asymmetrical for a greater area of uninterrupted glass.

The sliding panel on Centor’s 261 Integrated Sliding Window has been designed to align with the center mullion of the frameless fixed panel to provide a greater connection with outside, whether the panel is open or closed.

Integrated screens and shades

Centor offers the best retractable fly screens for bifold doors, accompanied by innovative shades that are built into the frame. Available on our 200 and 400 Series doors and windows, this unique offering allows homeowners to enjoy inside-outside living without the traditional compromises associated with large openings – insects, glare and loss of privacy.

Homeowners across the world are delighted with their integrated screens and shades. In the Portland, Oregon Heather appreciates the built-in screen: “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.”

While in the United Kingdom, Gillian is pleased with her built-in shades: “The integrated blinds really appealed to me. 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.” 

Our built-in blockout shade also enhances the thermal properties of the door, with independent tests showing a reduction in the U-value by 17%.
