STP Magma is the material with combined sound and heat insulation properties. It is used in car noise insulation for the second layer treatment of such areas as the floor in the passenger compartment and trunk, doors, rear fenders. Flexible and easy to install. Reliably held on the surface of the vibration damping material due to the moisture-resistant adhesive layer. Does not absorb water and is not afraid of its prolonged exposure. By combining the functions of the two layers, the use of Magma reduces the time spent on car treatment.
