Noise absorbers made from polyurethane (PU) foam

Our acoustic foam made from polyurethane (DIN abbreviation: PUR) is a dark gray, open-cell foam material with excellent sound-absorption capabilities.
Our PUR foams score with their softness and elasticity while offering high shape stability. In combination with low weight and excellent acoustic effectiveness, these properties turn our materials into universally usable high-quality sound absorbers for a wide range of applications.

In addition, they are physiologically safe, score with high thermal resistance and are easy to cut with a carpet knife. Fixation per special soniflex adhesive or screws guarantees ease of installation.
soni SPECIAL ADHESIVE
Cartridge / Set of 6 or 12 cartridges: cartridge of 310 ml
Our soni SPECIAL ADHESIVE is an ideal adhesive for spot and full-surface fixation of sound-insulation materials and acoustic elements made of open-cell foam, especially melamine and PUR foams. The solvent-free, stable soni SPECIAL ADHESIVE provides excellent adherence to typical building materials, such as concrete, plaster, masonry, cement and wood. With the elastoplastic, single-component polymer adhesive, our open-cell foam panels can be glued directly to the wall or ceiling. Our soni SPECIAL ADHESIVE is available in 310-ml-cartridges, in sets of 6 or 12 cartridges. Please note: soni SPECIAL ADHESIVE is not suitable for PE foams such as soni RESIST. Keep out of reach of children!

soni 471 SK
Thickness: 10 mm
soni 471 SK is a sound absorber made from PUR- foam. In a thermal embossing process its surface has not only been provided with an attractive diamond pattern, but also compacted and sealed, making it very robust and dirt-resistant. What is more, the air-permeable embossing improves the material’s acoustic effectiveness - especially in the frequency range of engine noise. Our soni 471 SK acoustic foam scores with high hydrolysis resistance and is predominantly used in the automotive industry. For instance, soni 471 SK is ideally suited for use as sound-absorbing and heat-insulating interior lining in mobile homes, vintage and classic cars or other vehicles. It meets the fire safety standards for the automotive industry as set down in FMVSS 302 and DIN 75200.   soni 471 SK is easy to cut to the desired size and shape with a carpet knife. Its low weight as well as the optional self-adhesive rear face make for easy and time-saving installation of the material.

soni 491 SK
Thickness: 10 mm
soni 491 SK is a PUR acoustic foam coated with a micro-perforated film. The sound-permeable film prevents the penetration of dirt and liquids and can be wiped clean. Our soni 491 SK acoustic foam has proven its effectiveness in many years of practical use, successfully minimizing noise levels and providing thermal insulation in engine compartments and vehicle interiors. It meets the fire safety standards for the automotive industry as set down in FMVSS 302 and DIN 75200. Also for the insulation of your roller shutter box we can recommend the PUR foam without restrictions.  soni 491 SK scores with high hydrolysis resistance and hence significantly higher aging stability.The material is easy to cut to the desired size and shape with a carpet knife. Moreover, the self-adhesive rear face makes installation fast and easy.

soni COMPOSITE
Color: black | Thickness: 32 mm
soni COMPOSITE is a combination product made from our synthetic soni EVA heavy layer and an acoustic foam laminated with a decorative felt layer. This ideal combination ensures a twofold noise-control effect: sound absorption plus sound insulation – for especially high overall effectiveness in reducing the noise level. soni COMPOSITE is particularly suitable for sound-transmission insulation. Mounted on the wall towards the neighbor’s apartment or behind a so-called curtail wall, for instance, our two-layer acoustic product achieves a noticeable noise reduction. For individual design options, you have the choice of various felt colors. Using a carpet knife, you can cut soni COMPOSITE to the required size and shape. The self-adhesive equipment of the rear face serves primarily as an installation aid.

soni DECOR
Rear face: not self-adhesive (nk) | Thickness: 30 mm
Our soni DECOR acoustic foam consists of polyurethane- foam laminated with a sound-absorbing non-woven surface layer. The black polyester non-woven is extremely robust as well as oil- and fuel-repellent. Due to the resistant non-woven surface, soni DECOR is widely used in technical applications. For instance, soni DECOR is ideally suited for use as sound-absorbing and heat-insulating interior lining in mobile homes, classic cars or other vehicles. Also in your home workshop, soni DECOR will achieve an effective noise reduction. Using a carpet knife, you can cut soni DECOR to the required size and shape. The material’s low weight as well as the optional self-adhesive rear face make for easy and time-saving installation. For fixing the non self-adhesive version we recommend our soni SPECIAL ADHESIVE.

Installation

On request, nearly all our products can be delivered with self-adhesive rear faces, enabling easy, clean and time-saving installation – perfect for retrofit applications in rooms that are already in use.

Noise control

Thanks to their open-cell structure, our noise protection materials absorb sound waves and effectively attenuate bothering noise. A satisfactory result can already be achieved by lining 30 to 50 % of the ceiling and wall surfaces.

Fire protection

Many of our noise-control products are classified as flame-retardant according to DIN 4102 or DIN EN 13501. Please contact your local authorities in advance for information about the required fire protection class.
