Architectural challenges

Location

One of the most often overlooked steps to get good door performance is selecting the right components for the right application. It is crucial to learn about the importance of location and exposure in choosing door components.

Location of a door on a home often influences what is expected of the sill in terms of performance and aesthetics. Exposure refers to the amount of direct wind and rain that the door unit will endure. Front doors typically have partial overhangs, giving them only medium exposure. Patio and back doors typically have no overhang, and may also be subjected to runoff water from a multistory wall above them. These doors experience the highest exposure, and require the highest performance from a door sill, frame and weathersealing.
