In order to design automotive parts that stay competitive, it&#;s important to understand some details behind automotive weatherstripping. Weatherstripping (or weatherseals) is the system that seals any openings in a vehicle to keep out weather conditions. The word is also used to describe the actual materials used to implement these sealing systems.

Weatherstripping (and other sealing solutions) are used for all sorts of automotive applications. They are needed wherever the interior compartment of an automobile or other form of transportation needs to be sealed from the environment. The material you use needs to integrate and function well with the body design of the vehicle.
An important factor to consider when selecting material for automotive weatherstripping is the engineering of the parts. Let&#;s take a look at several engineering factors.
Whether the vehicle is operating at full speed or parked, the weatherstripping must maintain full functionality.
Also, weatherstripping must be flexible enough to address vibrations caused by vehicle movement.
The material used must be able to handle subzero temperatures. Conversely, it must be able to tolerate extreme heat and extensive exposure to the sun.
Of course, auto weatherstripping should also withstand liquids including gasoline, oil, and methanol (windshield washer fluid). Bumps and vibrations cause movement between the body of a vehicle and movable parts like windows and doors. This movement might cause water to penetrate the vehicle. Weatherstripping must be applied to seal the gap.
Another important factor to keep in mind is that weatherstripping can play a part in keeping noise out of the passenger compartment, which impacts ride quality. Similar to how the movement between body and movable parts mentioned above causes water to enter, the movement can also cause noises like rattles, squeaks, and creaks to pollute the passenger compartment.
If we consider a standard four-door vehicle, we can get an idea of weatherstripping size requirements. Each door would need at least 20 feet of material. Every window would require at least 10 feet of material. Trunks would need much larger amounts of material, due to how much more space it needs to seal.
Automotive weatherstripping is usually made of these materials:
Weatherstripping performance can be optimized with the application of specialty coatings. Of course, the coating applied must sufficiently adhere to the material used to manufacture the weatherstripping. When the proper coating is chosen and bonds to the weatherstrip, it can offer several benefits such as:
Weather stripping is the rubber material that edges your vehicle&#;s doors and windows, creating a safe, dry seal between your car&#;s interior and the great outdoors.

Like all of your car&#;s parts and systems, weather stripping requires a little maintenance time and again. How can you tell that your weather stripping is worn out and ready to be replaced?
Automotive Training Center decided to help you out with three symptoms that may point to the need for a weather stripping replacement.
Have you noticed heightened road noise in construction zones or that highway hum associated with left lane driving getting louder? If so, the elements may be taking their toll on your weather stripping and disturbing that resilient seal that acts as a sound barrier for your cabin.
Replace your weather stripping and you&#;ll no longer have to keep twisting the volume dial on your stereo to enjoy your podcast on your commute.
Not only does weather stripping seal noise out, it also prevents moisture or condensation from entering your car on a rainy day. That being said, if you notice wetness around your windows or door or trunk jambs when your windows and doors have both been shut, your weather stripping likely needs to be replaced.
Check the back doors too! As you can imagine, you&#;ll want to get any source of water inside your vehicle cleaned up right away and stopped at the source to prevent the damp environment that&#;s friendly to mold and mildew.
Finally, weather stripping&#;s seal separates your cabin climate from the heat or cold outside the vehicle. If you have to blast your car&#;s heater or air-conditioning unit and only feel these affects for a short while (and have ruled out any possible issues with these systems), your efforts may be going (literally) straight out the window and replacing your weather stripping is a worthy fix!
If you&#;ve resolved that your weather stripping needs to be replaced, you have a few options to restore the seal. It&#;s possible to find the cracked or damaged section and just replace that spot. However, it&#;s more effective in the long run to replace all weather stripping at once. This way, you know you&#;ve fully tended to the problem and that it&#;ll be a good while before you have to revisit it.
Either aftermarket or factory replacement car weather stripping is available. When you&#;re ready to make the replacement, perform the following:
