Hinges design enables the sash to be opened in any position from 0 to 45 degrees, which allows an easy approach to the opened window. The open sash also provides a wide view to the outside and access to the roof e.g. in order to perform maintenance works.

OptiLight brand belongs to FAKRO group (the second largest manufacturer of roof windows in the world). OptiLight products offer high quality at an affordable price. Modern technology of material handling and processing, quality control in every stage of production, as well as tests performed by independent laboratories guarantee high quality of OptiLight skylights.

Advantages of OptiLight windows

  • OptiLight VK window is equipped with manually operated air inlet positioned in the top part of the frame. It provides fresh air up to 19m³/h (at a pressure difference of 10Pa) when the window is closed.
  • The window is closed with the use of the handle positioned at the lower part of the sash. It allows locking the window at three points: closed tightly and two micro-opening positions.
  • The technology of VK roof windows production and their appearance from the inside of the room causes that they can be joined with VB pivot windows into combinations. Advantage of such solution is better illumination of the living space, high aesthetics, functionality and possibility of cleaning external pane in pivot as well as in top hung window.


  • High quality wood  wooden elements of the OptiLight windows are made from especially sorted, highest quality pinewood which is bonded in layers, impregnated, and coated with an ecological acrylic finish. The wood is protected on the outer surface with weather and UV resistant aluminium profiles.
  • Additional wood protection: the wooden sash has been equipped with plastic corners protecting those fragile areas from moisture.
  • Metal clading: metal cladding elements of OptiLight windows are made of suitably thick aluminium sheet which adds to their resistance to mechanical damage during transport, installation and window usage. The sheet is coated with polyester which is fully weather-resistant.

Space between panes is filled with noble gas – argon. The window is also available in version with external pane with an easy maintenance layer. The internal pane features a low emission coating, which minimizes heat losses in the room in the winter and reduces heat gains during the summer. Glazing U-value = 1,1 [W/m²K].

Flashings (sold separately)

A flashing is an essential element allowing correct installation of a roof window in the roof slope. The precisely designed systemic elements of the flashing enable tight and durable integration of the window with roofing. It is very important as the main task of the flashing is to drain water and snow away from the window and protect it against the wind. The flashings are manufacture from aluminium sheet, coated with hard-wearing polyester lacquer. The basic colour is Grey – brown (RAL 7022), thanks to which windows go well with standard colours of roofing materials.

Flashings are used for connecting the windows with roofing and it is the roofing which decides about their selection.
