Car insulation is a set of mats, blankets and sponges located in different spots around the car's body. They protect the car's cabin against the noise and vibrations produced by the engine, suspension or speed. To reduce the car weight or for economic reasons many car manufacturers reduce the number of insulation materials fitted in their cars. Therefore, you might want to consider installing additional insulation in your car on your own. You can choose from a large number of different solutions suitable for most car models.
