soni 1116 ALG
Thickness: 4 mm
soni 1116 ALG SK is a two-component material for heat protection and acoustic insulation: The heat-resistant surface layer is made from a high-quality aluminum foil and reliably reflects heat radiation. The bottom layer consists in a quilted glass fiber mat, which is responsible for the heat insulation effect as well as for the sound-insulation properties. Our soni 1116 ALG SK is optimally suited for use in the hot zones of vehicles and machines. When mechanically fixed, the acoustically effective insulation mat withstands temperatures of up to 600°C. The aluminum surface doubles as barrier preventing the penetration of oil, water and fuel. The material meets the fire safety standards for the automotive industry as set down in FMVSS 302 and DIN 75200. Simply use a carpet knife to cut soni 1116 ALG SK to the required size and shape. The optional self-adhesive rear face facilitates the installation of the panels.

Description


Sound insulation for machines | technical equipment | compressors

As a rule, any machine, whether large or small, will generate noise. The resulting noise level can be very unpleasant. This is why we recommend enclosing the machine or other equipment with a noise-reducing casing - ideally at a distance of about 30 cm from the actual noise source. The enclosure (made of wood, plastic or sheet metal) should be lined on the inside with sound-insulating material. Perfect for this use are our products soni RESIST, soni COMPOSITE and soni WAVE.

If the machine is located outside, our soni RESIST is the material of choice. It has both sound-absorbing and sound-insulating properties and hence an especially high overall soundproofing effect. Furthermore, soni RESIST is weather-resistant. If, in addition, the sound-absorbing material will be exposed to sunlight, we recommend our soni RESIST UV. With its unique UV stability, it is specially designed for outdoor use. For those particularly noisy compressors, the ideal choice is our soni SB 700, a highly sound-absorbing polyester fleece combined with a heavy layer. This optimum combination insulates and dampens in equal measure and thus provides excellent noise protection.

As a further measure, the utility room or workshop containing the compressor, ventilation/air conditioning equipment or a noisy machine can be insulated using sound-absorbing materials. This prevents any annoying noise from being transmitted to neighboring rooms or rooms above. Contact us to find out more.

Chiller noise control

After the successful acoustic insulation of a chiller, a customer wrote:
The problem: The noise caused by the chiller in the storage room was a nuisance in the living quarters above the butcher’s shop. When installing the chiller, we had already made sure to have it acoustically decoupled from the floor so as to prevent solid-borne noise transmission as far as possible. But we also needed to do something to reduce the air-borne noise which was still too loud to be tolerable.
The solution: The installation of soni WAVE sound absorption foam panels on the ceiling of the chiller room has led to a substantial reduction of the sound pressure level. This proved to be a perfect secondary sound protection measure because it prevents the transmission of the air-borne noise caused by the chiller through the ceiling to the living quarters.

Sound insulation of an air compressor

The automobile detailing company E. from Germany, tells us what they did to sound-proof an air compressor:
Our air compressor emitted so much noise that it was impossible for our employees to work right next to it. For this reason we built a solid-wood enclosure for the compressor. Then we lined the interior surfaces of the enclosure with the acoustically highly effective noise absorption foam soni WAVE 50 mm, with self-adhesive rear face. The soni WAVE acoustic foam panels were easy to cut to size using an ordinary carpet knife. For installation, we removed the protective film from the self-adhesive layer on the rear face and then secured the fitted pieces on the corresponding surface areas.
In conjunction with the solid wood of the enclosure, the soni WAVE sound protection panels now ensure optimum acoustic insulation of our air compressor.

Sound insulation of a machine

A company told us about how they achieved effective sound insulation of a machine:
As the noise level in our factory was much too high, we needed to implement sound protection measures. We covered the interior surfaces of the housing of an especially noisy saw with 50-mm thick soni RESIST acoustic panels without self-adhesive rear face. This achieved a double effect: sound absorption and sound insulation. After the installation of the sound protection panels, the machine was much less noisy. The audible noise was reduced to a fraction of its former level.

Noise reduction in a basement boiler room

That’s what one client writes about installing sound absorption panels in a boiler room:
The installation of sound-absorbing soni WAVE acoustic foam panels on the ceiling of our basement boiler room has led to a substantial reduction of the noise from the boiler. The soni WAVE 30-mm noise reduction panels with self-adhesive rear face are perfectly suited for self-adhesive fixation on a smooth concrete ceiling.
As the soni WAVE panels on the ceiling reduce the noise level in the boiler room, considerably less noise is transmitted to the living space on the floor above.
In addition to covering the ceiling with sound-absorbing soni WAVE acoustic foam panels we had a sound insulation housing built around the heat pump in the boiler room. The inside of the housing is also lined with soni WAVE sound absorption material in order to achieve noise reduction right at the source.
The two noise reduction measures – which, by the way, are easy to carry out by skilled laypeople – now ensure optimum noise insulation of our boiler room.

Sound insulation of a swimming pool filter pump in a plant room

One of our customers sent us the following report on a sound insulation project for a swimming pool filter pump:
With the swimming pool filter pump running, the plant room became very noisy and the annoying noise was also clearly audible outside.

Lining a large part of the interior walls of the relatively small plant room with 50-mm thick soni WAVE sound absorption panels has led to a substantial reduction of the sound level. The soni Wave panels are glued to the wall using the special adhesive from soniflex.

The result: The foam panels with their undulated “egg-crate” surface now absorb much of the noise emitted by the swimming pool filter pump. Outside of the plant room, the noise is hardly audible anymore .
