In hollow metal a kerf is a notch in the frame which serves as a channel to insert weatherstripping. When the door is closed, it presses against the weatherstripping creating a seal against the elements. Additionally, what is kerf door seal? This type of weatherstripping is made from a long strip of soft, flexible foam with a tear-resistant cover. Integrated into the foam is a barbed, PVC plastic strip that's inserted into a saw kerf cut into the door frame.
Properly installed, it won't buckle or bulge, creating a firm, lasting seal around the top and sides of the door. A door sweep is a small piece of plastic or rubber, attached to an aluminum carrier strip and fitted across the bottom of a door. It provides a weatherproof seal and prevent drafts from coming in under the door. This fin wedges into the kerf and holds the weather strip seal in place by friction.

Apply a small bead of outdoor silicone caulk along the bottom of the kerf seal where it meets the threshold on both sides of the jamb. Use utility shears to cut through the vinyl seal and a hacksaw to cut through the metal strip attached to the vinyl seal to equal the doorjamb measurement. Fit the door seal against the jamb.
