Description
Our soni 491/STL noise-control panel is a highly effective sound-insulation product based on PUR foam, equipped with a micro-perforated surface film and additionally with a heavy layer. This clever combination of two different acoustic materials ensures both sound-insulating and sound-absorbing properties in one product. soni 491 STL is suitable, for example, for boosting the sound insulation effectivity of a wall, partition wall or ceiling.
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 491 STL in the empty spaces between the laths and cover them with plaster boards or particle boards screwed to the laths. 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”.
If you do not have the tools and/or the time to cover the sound-insulation panels with plasterboard or chipboard, we recommend our soni COMPOSITE as an alternative sound-insulation material. In contrast to soni 491 STL, soni COMPOSITE scores with a stylish decorative felt surface that is available in different colors and excellent for visible sound-conditioning materials.
