Automotive weatherstripping is used extensively aboard automobiles, and can be found anywhere the interior compartment must be sealed from the environment.
For example, the weatherstripping must function the same while the vehicle is parked and at full speed; be flexible to accommodate motion vibrations; endure extreme temperatures of hot and cold; withstand long periods of sun exposure; and resist automotive liquids such as oil, gasoline, and windshield washer fluid (methanol).
Weatherstripping also plays a part in maintaining satisfactory ride quality in the vehicle, being partially responsible for sealing noise out from the passenger compartment.
Furthermore, this relative movement can cause noises such as squeaks, rattles, and creaks to be heard within the vehicle.
Weatherstripping around openings – especially doors and windows – is used in buildings to keep out weather, increase interior comfort, lower utility bills,[2] and reduce noise.
