Description
Car sound deadening SGM Base 1.7 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.
The material features an optimal 1.7 mm thickness, which is sufficient for effective performance in low-vibration areas of the body: doors, roof, trunk lid, and hood. SGM Base 1.7 mm is easy to install—a thorough pass with an application roller is enough for a reliable bond.
During operation, avoid proximity to high-heat components such as the engine, exhaust manifolds, and exhaust system.
Advantages
- The most economical choice for foundational soundproofing;
- Ideal for treating low to medium vibration areas;
- Perfectly suited for do-it-yourself (DIY) projects;
