Keylite Roof Windows from SNS Building Products

  • Expanding Thermal Collar:
    Simply pull away the release tape to allow our unique Expanding Thermal Collar to expand, filling the gap between the window frame and the
    roof: A proven measure in reducing the cold bridging effect.
  • Ventilation Handle:
    Our slimline ventilation handle has a new contemporary style, designed to provide a comfortable opening of both the window and ventilation flap. The handle allows for trickle ventilation, even with the window fully closed and securely locked.
  • Maintenance Free Hinge:
    The hinge, being the most vital component of the window, is the only operational part that moves. Keylite has eliminated the maintenance
    requirement of this component.
  • Sash Hinge Finger Springs:
    The sash hinge finger spring allows the sash to be installed back into the frame in one smooth, effortless motion.
  • Flick-Fit Brackets:
    Pre-fitted Flick-Fit brackets are easy to use and make Keylite faster from the box to the roof.
  • Click-Fit Hood & Cover Flashings:
    Simply click the hood under the clips and secure.
  • Streamlined Fit:
    Allowing the window to sit lower in the roof, the hood is designed to create a low profile.
  • All Weather Ventilation:
    Keylite Roof Windows all provide trickle ventilation, even with the window fully closed and securely locked. The built-in insect filter ensures only clean, fresh air passes into the room.
  • Reinforcing Steel:
    For added strength and stability, the Keylite Polar range has steel added to it’s larger windows.
  • Warm Edge Glazing:
    All glazing is now upgraded as standard to warm edge, which adds protection against condensation.
