The two basic ways noise penetrates into the passenger compartment of a car is via vibrations of the car body and airborne sound entering the vehicle, STP have designed specific materials to tackle each area:
Vibration Absorbtion: These materials are mounted on the interior of the car body and have the following benefits:
-Absorbing vibration of the car body
-Sealing properties of these products prevents car body from corrosion
Sound Absorbtion: This group is aimed at absorbtion of noise from the vehicle and is designed to be mounted near the source of the noise. ie. engine and wheels.
-Absorbtion of unwanted noise
-Heat Insulation
Sound Insulation: Meant for protection of the passenger compartment from external airborne noise and is applied to the doors, floor and roof.
-Insulation of external noise
-Heat Insulation
-Moisture Resistance
Sealers: These materials are for tight sealing of wire holes, contacting elements of interior panels and are meant to reduce squeaking and sound penetration into the passenger compartment
Application of the materials is very easy, all products have a peel and stick self adhesive backing. A typical installation would include a combination of a few different groups and is heavily dependant on the car model and make. Your local STP stockist will be able to advise you of the best combination of products for your specific application.
