Shumanet-BM boards are inserted into the sheathing cells. In acoustic suspended ceiling structures, the boards are installed in the space between the suspended ceiling and the floor slab. Shumanet-BM is installed behind the suspended ceiling or attached to the floor slabs using plastic “mushrooms” for attaching the insulation boards. When used in non-hermetic structures, to prevent the emission of material particles into the environment, it is recommended to first wrap Shumanet-BM boards in a sound- permeable non-woven fabric such as spunbond. #### 󠀁[Video](https://uzbuild.com/en/shumanet-bm-premium-acoustic-mineral-plywood/#1704280671563-a2ee8262-50a5)󠁿 #### 󠀁[Documents](https://uzbuild.com/en/shumanet-bm-premium-acoustic-mineral-plywood/#1703053158754-6b20a25b-e7d6)󠁿 [[[Technical data sheet for Shumanet-BM](https://www.acoustic.ru/data/pdf_files/Shumanet_BM_tehlist.pdf) [[[Catalog of materials for sound and vibration insulation](https://www.acoustic.ru/data/pdf_files/katalogue_sound_vibro2017.pdf) [[[Download all certificates in one archive](https://www.acoustic.ru/data/goodscatalog/goods/6/certs/ru_6.zip) ### Certificates and patents (Russia) #### Rejection letter #### 󠀁[󠀁[󠀁[󠀁[ [[[Shumanet-BM Premium Acoustic Mineral Plywood.
