When installing weatherstripping around a door jamb, the goal is to create a seal between the door and the jamb to prevent drafts, air leakage, and moisture infiltration. While it's important to create a good seal, it is generally not recommended to make the sides of the door completely flush against the weatherstripping when the door is closed.
The weatherstripping should be applied in a way that allows the door to close easily without excessive force. If the weatherstripping is too tight or compresses the door too much, it can cause the door to stick or create friction, making it difficult to open and close.
Instead, the weatherstripping should be applied in a way that provides a good seal while still allowing the door to close smoothly. This usually involves positioning the weatherstripping so that it contacts the door firmly but not excessively. When the door is closed, the weatherstripping should compress slightly, creating a seal but still allowing the door to move freely.
It's worth noting that there are different types of weatherstripping available, such as adhesive-backed strips or compression strips, and the installation method may vary depending on the specific type you're using. It's always a good idea to refer to the manufacturer's instructions for the weatherstripping you've purchased to ensure proper installation.
