Noise-control retrofit measures for walls or ceilings (drywall construction)
For sound insulation in drywall constructions we specifically recommend the following products:
soni COMPOSITE: This is a high-quality combination product made from our soni EVA synthetic heavy layer and an acoustic foam layer that is laminated with a decorative felt surface. These materials complement each other perfectly in acoustic terms and ensure that the product provides both a sound-absorbing and sound-insulating effect, making it the perfect sound insulation for drywall-type curtain walls.
soni 491 STL: This acoustically effective noise-control panel consists of a PUR foam in combination with a heavy layer. Its outstanding sound absorption values and excellent sound insulation efficiency make it the ideal product for retrofit noise-control measures on the walls or ceilings of all kinds of buildings, ensuring a significant reduction in noise. soni 491 STL can be used for so-called cavity damping, which means that it is mounted in the empty space behind a curtain wall. Typical applications for soni 491 STL are retrofit measures for the acoustic insulation of walls, partition walls or ceilings.
Advantages of our soni products for retrofit sound insulation measures
The different soniflex products recommended for drywall-type retrofit measures for the effective sound insulation of walls and ceilings score with excellent sound insulation values and outstanding sound absorption capacity. In addition to significant noise reduction and effective sound insulation, our materials installed on walls and/or ceiling will also provide thermal insulation and hence considerable energy saving benefits. Thanks to their outstanding quality, our soni COMPOSITE and soni 491 STL sound insulation panels are not only particularly robust, but also offer high ageing stability.
Sound insulation in drywall constructions – special tips for perfect outcomes
For the retrofit sound insulation of a dividing wall between apartments or neighboring terraced houses, we recommend the construction of a curtain wall behind which
soni 491 STL inserted. Our soni 491 STL sound insulation panel is a highly effective sound insulation product combining a bitumen heavy layer with a PUR foam that is additionally protected by a micro-perforated film.
For acoustic decoupling and to prevent sound bridges, we suggest applying our soni NBR sealing tape to the slats of the curtain wall.
As an alternative, you can use our noise-control products soni COMPOSITE , a high-quality acoustic foam with very good sound absorption and sound insulation efficiency.
Key features of soni 491 STL and soni COMPOSITE:
- Excellent sound insulation values
- Good sound absorption capacity
- Additional energy-saving thermal insulation effect when used as wall or ceiling liner
- High ageing stability
- Free of mineral fibers, physiologically safe

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.
