Weatherstripping is commonly used to seal the openings around doors and windows to safeguard a home from the elements.  It can block water from coming in, and can also be used to keep interior air inside which can help save energy from heating and air conditioning.  It can also be used in cars to seal trunks, or to add traction to objects like boots and hand-held tools.
