Weatherstripping is the material used to create the seal in the space (or margin) between the door and the jamb, and also between the bottom of the door and the threshold.
The weatherstripping applied to the side jambs and header can be made from thin flexible metal, such as copper or aluminium. It is also produced in a foam material wrapped in a plastic casing. This type is commonly referred to as neoprene. The jamb profile dictates which type will be used. We also offer other options for the various jamb types and the materials they are made from. Steel frames can be weatherstripped using materials with self adhesive backing or a type having a metal binder and a flexible vinyl gasket fastened with screws to the steel frame.
