Tips for purchasing energy saving weatherstripping for windows and doors:
Some weatherstripping materials are more durable than others. Since these materials must withstand extreme weather conditions, choose a material that is more durable because it does take time to install and will last longer. In applications where the weatherstrip will get wet, choose materials that won't asborb moisture; otherwise, the weatherstrip will freeze and swell.
Materials may include metal, wool felt, plastic such as vinyl or urethane, latex, silicone, neoprene rubber, or a combination of materials. For best performance and appearance, try to stay with the type of weatherstrip that came with the door and window. If you can't find a replacement, choose a type of weatherstrip that can be installed without nails and tacks, as they will damage the window and door frame.
Use a thickness that causes the weatherstripping to tightly press between the door and the door jamb when the door closes. Use a thickness that allows the window to function and to close tightly against the window frame and frame structure or sash.
Measure the length of the surfaces and purchase lengths of weatherstripping that can be applied in one, continuous strip along each side.
Types of weatherstripping for windows and doors include: V-type or tension seal, interlocking, pliable or rigid strips, foam or reinforced foam tapes, rolled or tubular, felt, and pile seal or pile seal with fins. Whatever type you choose, follow the instructions for applying the material. Since many weatherstrip materials use self-adhesive tape, cleaning the surface before applying is critical.
Additional weatherstripping for the door bottom includes: door sweeps, door shoe or door bottom, bulb or saddle threshold and frost-break threshold.
