Noise-control retrofit measures for walls or ceilings (drywall construction)

For sound-proofing partition walls between apartments or terraced houses we recommend the construction of a curtain wall using soni PROTECT R, a high-quality recycling product made from soft melamine foam. For such a curtain wall, a framework of 30 to 50 mm thick wooden slats is fixed to the wall, preferably on elastic spacers, e.g. soni NBR tape, to ensure acoustic decoupling.

soni PROTECT R scores with outstanding noise absorption and insulation effectiveness.
When mounted in the empty space behind a curtain wall, soni PROTECT R minimizes the propagation of any vibrations, substantially improving the constructive noise insulation.

Key benefits of the product:

  • High sound insulation effectiveness
  • Excellent sound absorption capacity
  • Additional thermal insulation effect saves energy
  • High ageing resistance
  • Free of mineral fibers, physiologically safe

Alternatively the hollow space oft he curtain walling can be filled with soni PUR-VS60. soni PUR-VS60 is a top-quality recycling varicolored PUR composite foam.

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 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 NBR sealing tape
soni NBR sealing tape is a closed-cell sealing material on the basis of NBR. A typical application of soni NBR is in the construction of a curtain wall, where it acoustically decouples the wooden lathing. Because of its suitability for contact with oils, e.g. engine oil, our sealing and decoupling tape has also proven to be an excellent solution for use in many technical areas as well as in vehicles, machines, enclosures, hoods and much more. Moreover, it is exceptionally hard-wearing and extremely resistant against deformation.  The self-adhesive rear face makes installation fast and easy. Roll length: 5 mThickness: 5 mmWidth: 40 mmHardness Shore 00: 31Tensile strength / ISO 1798: ≥ 205 kPa

Our soni PROTECT R sound-insulation panel is a high-quality recycling product based on melamine resin. What makes soni PROTECT R so special is its excellent sound-absorption and sound-insulation capacity, which allows for effective sound-transmission prevention. When mounted in the empty space behind a curtain wall or false ceiling, soni PROTECT R minimizes the propagation of noise, vibration and resonances – for improved sound insulation of partitions, walls and ceilings. This puts an effective stop to the transmission of ambient noise or annoyingly loud sounds from neighboring apartments. Advice on building a curtain wall:For a curtain wall, dowel wooden laths of 30 or 50 mm thickness to the wall. Ideally, an elastic layer is placed between the wall and the laths to prevent sound bridges. Our soni NBR sealing tape is the ideal solution for such an elastic mounting. Then insert our sound-absorber product soni PROTECT R in the empty spaces between the laths and cover them with plaster boards or particle boards screwed to the laths. For even more effective sound absorption, soni PROTECT R can be mounted on the wooden laths (30 mm) instead of being applied directly on the wall. The resulting air gap acts as an extra sound insulation. To optimize the curtain wall you can "decouple" the plaster board / particle board from the floor and ceiling as well as the adjacent walls by filling the edge joints with acrylic.For an example of a curtain wall construction for noise insulation purposes, please see the testimonial "Neighbors / Curtain Walling”.

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.
