Description
Car sound deadening SGM Base 3 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 sound deadener is an excellent budget solution for treating high-vibration areas: the floor, trunk, and engine compartment bulkhead. SGM also recommends Base 3 mm for doors and the roof, where it provides maximum vibration damping without compromising the application technique.
During operation, avoid proximity to high-heat components such as the engine, exhaust manifolds, and exhaust system.
Advantages
- An economical and practical material;
- Meets basic soundproofing requirements;
- Easy to install and affordable.
