Extra Wide Exterior Doors

You want them. They’re so impressive. They’re nearly impossible to get or have custom-built, and those extra wide exterior doors look magnificent when they are expertly designed and installed, only to disappoint at the following change of weather, because those extra wide exterior doors are likely to fail not long after installation.

What are you going to do?

If you find a custom millwork who is brave enough to build your extra wide exterior doors, it is certain they will have you sign a waiver of exclusion from any standard warranty they might offer on any of their other work on your project (which is normally a year). This is common for any unconventionally wide doors.

As all experienced millworks and custom door manufacturers know, a wide door is going to present problems for door warp. It’s simply the nature of the building materials which will move according to changes in the environment. Especially for extra wide external doors because one side faces the interior and the other faces the elements. This is a certain recipe for failure.

When the temperature is different on either side of the door, it will move. When it rains, or sunlight falls directly on the door, change in barometric pressure, just about any change will cause the door to move.

This is accepted as a standard in any type of door. In fact the AWI standard for a regular-sized door is to allow up to ¼” movement for any door up to 7 ft. tall and 3-and-a-half ft. wide to be considered “normal.” All door hardware is constructed to allow for this variance.

Once you exceeds the height and width of what is considered “normal” the differences are increased exponentially, and it doesn’t take much to have your wide doors become inoperable as they warp, bend, twist, or otherwise fail due to movement which will naturally occur.

That is, unless your extra wide exterior doors have Sing Core inside.
