Fixed lights and windows with mullions and transoms:
Fixed light is a simple solution which includes a glazing unit installed directly to the window frame. This is a way to increase light gain inside. A more complex variation could be a window with a fixed casement. This could be a case of historic buildings where it is required to maintain the outside face.
DK Windows product lines also include a wide variety of dividing possibilities for frames and casements: mullions, transoms, glazing bars and applied bars on glazing units. A single multilight window frame can be as big as 2,5 x 3,2 m.
Besides rectangular windows we offer solution for angular and rounded openings too.
