Product information STP Sonora - Multilayer insulation mat for noise reduction

The new STP Multilayer Sonora is a highly effective material for reducing noise in vehicles.
Ideal for high-quality audio installations and significantly reducing driving noise and road noise.

Structure of the multilayer mat:

•  soft deck sends
•  Sound-absorbing heavy layer
•  Sound-absorbing layer made of foam
•  adhesive layer

The use of two radically different mechanisms in one product results in a powerful synergy effect for sound level reduction (sound insulation and sound attenuation).
Important: Mulltilayer material is always applied to vibration-damping material (e.g. STP Black Silver) to achieve the best result.

Area of application:

Door inner panel, door panel

Packaging size:

• Size of the mat: 36.5 X 47 cm
• Thickness 5.2 mm
• Mass sqm/KG: min 2.2
• Contents per package: 10 mats = 1.71m²
