Functional sills on doors are designed to divert water in which direction?

Functional sills on doors serve the important purpose of managing water drainage to protect the interior of a building from water intrusion. These sills are specifically designed to divert water away from the door rather than allowing it to accumulate around the frame or flow toward the interior space.

When water encounters a functional sill, the design directs it away from the door. This helps prevent moisture from seeping into the door frame, which can lead to wood rot, mold growth, and other forms of structural damage over time. By efficiently channeling water away, functional sills effectively contribute to the overall durability and integrity of the door installation and the surrounding areas.

Understanding this function is crucial in home inspection as it highlights the importance of proper installation and maintenance of door sills to avoid water-related issues.
