The Vision Energy is a non opening pitched roof window. It’s an additional non opening window designed to be paired with an openable pitched roof window (as pictured). It’s ideal for letting light in and maximising the view from the room.

  • Dakea VISION ENERGY is a sloped, fixed (non-openable) additional roof window
  • It’s a three-pane window – known for having better U-value with both the glass itself and the window frame. This can reduce heating costs and thus reduce environmental pollution
  • Energy efficiency: Uw = 1.1 W / m2K, three-glass / two-chamber package
  • Dakea VISION ENERGY has toughened outer glass, extra heat reflecting coating and laminated internal glass
  • We recommend these non-opening roof windows for heated and inhabited rooms
  • Dakea VISION ENERGY windows come with a free Dakea Quick Install (RUC) underfelt foil collar. The Quick Install system reduces installation time and ensures that the structure is properly watertight
  • Dakea VISION ENERGY roof windows can be installed under an openable Dakea normal frame wooden roof window with triple glazing, installed in a roof pitch between 15°- 90°.
  • Not suitable for individual installation – needs to be installed in pairing with an openable Dakea roof window. See below for more details.

This non opening pitched roof window must be paired with additional flashing and an additional triple pane roof window. The size of this additional flashing needs to be determined by the size of the openable roof window installed above the fixed window.

Appropriate flashings include:

KUI: universal flashing kit for the fixed window on high profiled materials of 16-120 mm profile height.

KSI: slate flashing kit for the fixed window on roofing materials up to 16 mm overlapped thickness like slate or shingle, etc.

XCI: combi flashing kit for combi installations

We also have a vertical fixed roof window – the Vertica Energy – for vertical installations.
