Configurations

The sharp shadow line found on the AluK 58BW flush casement window is a result of the open-out sashes. Available in the following configurations: French casement, top-hung, side-hung, and fixed-lights. The flush shadow-line can also be achieved using dummy sashes.

You can also achieve the flush aesthetic in bay window styles, using the AluK Bay Pole for bay windows of any angle, and the Corner Posts for 90° angle windows.
