How are exterior doors typically installed?

Exterior doors are typically installed in a framed rough opening with a header supported by studs. This method provides a solid structure that allows for the weight of the door and its hardware to be properly supported. The rough opening is framed to the specific dimensions required for the door being installed, with vertical studs on either side and a horizontal header at the top. This framing allows for adequate support and ensures that the door operates smoothly, maintaining proper alignment and durability over time.

Using this method also facilitates the installation of insulation and weatherstripping, which are essential for energy efficiency and preventing air and moisture infiltration. A well-constructed rough opening plays a critical role in the overall performance and longevity of the exterior door, making it the standard method for installation in construction and renovation projects.
