Exterior Doors

Exposure Types Many homes have a covering over their front door also known as an overhang. Depending on the size of the overhang, your door may be partially or fully exposed to the elements. In these cases, it is important to consider the durability and construction of the door to make sure it stands up to the elements. Doorways can be grouped into three different protection levels: fully protected, partially protected, and unprotected.

Fully Protected Doorway Fully Protected Doorways provide the most protection for your doorway. The overhang extends the same distance as the unit is high but it also extends past the door on the sides to cover all angles of the door. Rain and snow may come in at an angle and with this type of doorway, the door will be protected from the elements.

Partially Protected Doorway Partially Protected Doorways provide protection for the top half of the door, but many times the bottom half is exposed to the elements. This is the portion of the door that is susceptible to water and moisture or the sun can break down the finishing seal over time by baking the bottom half of the door. The height of the opening is the distance from the sill to the ceiling.

The overhang (X) of a partially protected doorway must extend half of the height (Y) distance (X = 1/2 Y). If you have a height (Y) of 10 feet, the overhang of a partially protected doorway must come out 5 feet (X).
