Noise and heat insulation for cars | motorhomes | boats

When using motorized vehicles, loud engine noises, constant roaring or annoying clattering sounds often put an end to driving fun. Especially older vehicles often generate unnervingly loud noises. The remedy of choice here is to install heavy layers or a robust sound insulation material to prevent sheet metal parts, such as the vehicle’s floor or doors, from booming and vibrating. Our sound-deadening layers will stop sound waves from spreading throughout the vehicle. Thanks to their low thickness, our heavy layers (anti-drumming panels) soni HEAVY and soni EVA can be used also in places where space is limited.

We offer effective sound insulation solutions designed to meet the special requirements in vehicles, mobile homes and boats. soniflex acoustic products and soniflex acoustic foams score with excellent sound insulation properties while providing also insulation against heat or cold - and meeting the automotive flammability standard acc. to FMVSS 302.

A heat shield made of soni 1116 ALG, for instance, is suitable for use in engine compartments, the areas around and above the exhaust system and the catalyst, as well as any other places that need to be protected from radiant heat. Owing to its high temperature resistance of up to 450 °C, the glass-fiber material is the preferred solution for areas of the transmission tunnel and the exhaust tract. In the case of large vehicles, such as tractors, or where there is a particularly large amount of heat being emitted by the engine, soni 1116 ALG can provide optimal insulation against heat propagation between the engine compartment and the vehicle’s interior. In addition, the aluminum surface offers excellent protection against the penetration of oil, water and other liquids.


Sound insulation of a car/ motor

One of our clients tells us about sound-proofing his car: For the sound insulation of the motor compartment of a Caterham Super Seven, the acoustic panels soni WAVE, 30 mm, without self-adhesive rear face, were applied to the inside of the car body in the motor compartment. The result: Very satisfactory!!

Our recommendation for soundproofing a car or vehicle:
If there are any openings between motor compartment and passenger compartment, we recommend sealing them, because even small gaps affect the sound insulation. Please note: soni WAVE is resistant against cold and heat from -40°C to +100°C.

Sound-proofing of a vehicle

One client used our material to sound-proof his vehicle’s interior. Here’s what he told us:

To sound-proof the interior of my car I bought 50-mm thick soni WAVE sound absorbing panels and installed them on different surfaces inside the vehicle. The sound absorber foam with its undulated surface attenuates any sounds and reduces the noise level inside the vehicle to a point where it is perfectly comfortable.

Sound-deadening of a boat engine

Our client writes about his experiences with sound-deadening a boat engine:

In the scope of the complete overhaul of my 40-year old cabin cruiser I replaced the inefficient four-cylinder engine with a Mercedes-built diesel engine. My biggest worry was how to sound-proof the engine because the only thing separating it from the driver's cabin was a maintenance access cover.

So I built an accurately fitting engine cover out of 16-mm plywood and lined the entire engine compartment as well as the cover with soni WAVE sound insulation panels 50 mm not self-adhesive. To fix the material on the wood, I used soniflex special adhesive. The sound-insulation panels were very easy to cut with an ordinary carpet knife or a handsaw.

Diesel engines are known to cause quite a lot of noise in a rather unpleasant frequency range. I was positively surprised how much of the noise the soniflex noise control panels managed to absorb.

At the moment, the boat with the sound-proofed engine still sits on a trailer in the boathouse. A friend, with whom I shared the sound-deadening material ordered from soniflex, told me that the noise level would be further reduced once the boat was in the water. I am truly impressed with the effectiveness of your soni WAVE sound insulation panels in sound-proofing a boat engine and will gladly recommend your product.
