The process of sealing openings such as doors, windows, and trunks from the elements is called weatherstripping. The goal is to prevent rain and water from entering by either totally blocking it or by blocking the majority of it and returning or rerouting it. A secondary goal of weatherstripping is to keep inside air in. This saves in heating and cooling costs. You can use weatherstripping in your home to seal air leaks around movable joints.
You must detect where the air leaks are and determine you ventilation needs before applying weatherstripping. Then you have to choose a type of weatherstripping that will take the friction, weather, temperature changes, and wear and tear associated with where it will be applied. Choose a product for each specific location. More than one type of weatherstripping can be used to seal an irregularly shaped space. Also take durability into account when comparing costs.
