We recommend the following products:

soni COMPOSITE (heavy foil + PUR foam + non-woven surface)

• Sound absorbing as well as sound attenuating properties
• Mechanically robust surface, oil-, water- and fuel-repellent
• Suitable for use in hot and humid environments

soni HEAVY (heavy foil)

• Excellent sound insulation values
• High temperature resistance
• Dirt-repellent surface

soni HEAVY ALU (heavy foil)

• Excellent sound insulation values
• High temperature resistance
• Reflection of heat radiation
• The aluminum foil completely prevents the penetration of dust, water, oil or other pollutants

Recommendation:

If there are any gaps between motor compartment and passenger compartment, we recommend sealing them, because even small gaps will cancel out sound insulation effect to a considerable degree.
