Description
Car sound deadening SGM Base 4 mm is a foundational sound-deadening material made from a classic bitumen mastic and 60-micron aluminum foil. It provides primary protection against body panel vibrations and prevents corrosion of metal surfaces. SGM Base offers stability across a wide temperature range from -40°C to +100°C, allowing for use in various climates. The siliconized release paper on the adhesive side significantly simplifies the installation process.
This material is recommended for the most vibration-loaded areas of the car: the floor, trunk, and wheel arches. Despite its budget category, its increased 4 mm thickness delivers consistent vibration damping and basic protection throughout its service life.
During operation, avoid proximity to high-heat components such as the engine, exhaust manifolds, and exhaust system.
Advantages
- Maximum thickness at no extra cost;
- Basic protection of the body against vibration;
- Easy to install and affordable.
