How is sound reduction achieved?
Material selection and construction are crucial for how partitions handle sound.
Folding and block walls are made of aluminium profiles covered by surface-treated boards, intermediate insulation and sound-absorbing materials. With the right dimensions and well-considered sealing technique, we offer solutions to most sound requirements.
The sound requirements determine which of our walls is best-suited. We offer folding and block walls along the entire scale, from "sound-permitting" constructions with reduction values of Rw 41 dB up to highly sound-insulating walls with measured laboratory values up to Rw 53 dB.
The walls have been sound tested by the Swedish Testing and Research Institute (SP).
General guidelines for sound insulation
R’w 48-51 dB
Provides conversation privacy. Shouting and loud business can, however, be heard. A sound insulation level that, nonetheless, offers acceptable conditions in environments where the requirements for confidentiality are not complete but the requirements for privacy are clear.
R’w 44-47 dB
Provides some conversation privacy. Some words in loud conversations may be heard but not really understood. A level of sound insulation that can be considered a relatively high standard in, for example, offices where work surfaces are to be separated from conference rooms.
R’w 40-43 dB
Loud conversations can be understood but are at the same time difficult to distinguish in detail. A sound insulation level that can be considered as the lowest standard, where there are requirements for sound insulation and privacy.
R’w 32-39 dB
Regular conversations can be heard in the lower sound isolation levels. In the higher levels, single words can be heard at normal conversation loudness but can be difficult to understand. A low insulation standard that may be acceptable in cases where low requirements are placed on sound insulation.
Sound environment is improved with good acoustics
The acoustics in the room are caused by sound bouncing between walls, floors and ceilings. By reducing and/or controlling how the sound is amplified, the room and the sound environment will feel more comfortable.
Winab's acoustic walls have an effective sound absorber, placed behind fabric. The wall contributes both aesthetically and acoustically to the well-being in the room where it is installed.
