GGLS STUDIO window is an innovative new type of product with the feel of a combi solution, but with the ease of a single installation. The STUDIO window is composed of three GGL FK06 sashes combined into one frame, consisting of two manually operated FK06 sashes and one fixed FK06 middle sash to provide an unobstructed view and an aesthetic design. The combinations of more windows within one frame form the conceptual foundation for the STUDIO window and adhere to the same well-known installation principles as a single GGL.  Can be installed in roof pitches from 15-90°

  • The three sashes in one frame construction secure unobstructed views combined with easy installation.
  • Two manually operated windows on each side of a fixed sash allow for plenty of daylight and fresh air.
  • The STUDIO window only comes in one size GGLS, white painted with a IGU 0066 pane and alu. cladding
  • The STUDIO window spans a width of 1837mm. The height is the regular FK06 height of 1178mm.
  • Fully assembled the window weigh 100kg. The frame and fixed middle sash alone weigh 40kg.
  • The STUDIO window can only be installed in Red Line level, due to flashing installation principles it is not possible to install in flush. All internal DSP fitting size FK06 will fit the STUDIO window, you just need three.

The frame and sash are made of high-quality laminated pinewood coated with impregnation and layers of water-based acrylic white paint.
