Copper Weatherstripping

Copper weatherstripping is the traditional type of weatherstripping used in wood jambs with wood doors. Most older homes will re-quire copper weatherstripping because the door jamb is non-kerfed, meaning that there is no recess or slot cut in the jamb leg to accept and hold the back edge of prefabricated weatherstripping. The dia-gram above shows how the copper weatherstrip acts as a cushion between the door and the jamb to fill the gap between the door and the jamb creating a seal.
