The illustrations below are intended to show the variety of opening combinations that are possible to configure. Please be sure to pay attention when configuring double sash windows and doors. With a mullion, you have a central piece physically separating each window whereas if you would like the ability to open both simultaneously, or simply do not want a mullion, ensure that only one of the two sashes is fitted with a turning hinge (a triangle symbol) and that the second shows a turn and tilt fitting (i.e. two triangles).
We strive to present our customers with the clearest and most useful information possible. Thus, it is important to note that on all of our window symbols below (and throughout the site) are shown from the perspective of someone inside the room looking out.
Every triangle depicted represents a way of opening, while the use of the plus symbol "+" represents a glazing type which cannot be opened. Remembering the simple guidelines will make configuring your windows as easy as possible. Nevertheless, if you have any questions or are ever unsure about part of your order, please feel free to call us!
