Car SPL special sound deadening SGM Armor

The SGM Armor 8 mm is an ultra-rigid, frame-reinforced vibration damper from the SPL series, featuring a 90-micron aluminum foil. It is based on a high-strength bitumen-polymer mastic engineered to withstand extreme acoustic loads. Thanks to its increased mechanical loss factor, it effectively suppresses the propagation of destructive vibrations through the vehicle’s body and minimizes residual structural noise.

During installation, SGM Armor forms a sealed bond with the metal, creating a moisture- and air-tight barrier that provides additional corrosion protection. The adhesive layer is protected by a siliconized release film, which safeguards it from damage and contamination until application.

Its increased 8 mm thickness makes it a versatile solution for any open surfaces exposed to high sound pressure: doors, roof, floor, and trunk. The material provides comprehensive protection of the body against vibrations of any intensity. For maximum effectiveness, heat the material to 60°C during installation and press it firmly onto the surface with a dedicated application roller.

Using this material increases the sound pressure level (SPL) inside the vehicle cabin by enhancing the structural rigidity of the car body.
