Door thresholds and gaskets are way more useful than you may think and are used for several purposes. Its primary purpose is to seal underneath and/or around a door to protect the outside weather from entering. The threshold or gasket protects the interior by keeping out drafts and rainwater or heat that usually come inside through gaps underneath or around the door. They are also used as a barrier to keep insects and other small pests from entering inside. In addition, applying a door sweep to the bottom of an entry door is another popular way to block drafts and insects from entering from underneath a door.
