Shumanet-BM Premium Acoustic Mineral Plywood
Shumanet-BM Premium Acoustic Mineral Plywood
Shumanet-BM basalt-based mineral slabs are one of the most effective solutions in the class of sound-absorbing building materials. Mandatory quality control of each slab ensures consistently high acoustic and performance properties of this product.
Shumanet-BM is a basalt sound-absorbing mineral wool board (NG, non-combustible), manufactured using advanced technologies at the Acoustic Group production facilities. Its low specific gravity (47 kg/m³) ensures minimal load on supporting structures and installation without the use of specialized equipment.

Scope of application
The material is designed to fill cavities between supporting structures and sheet cladding during the installation of frame structures in residential and industrial buildings. The high sound absorption characteristics of Shumanet-BM allow for effective sound insulation with minimal weight gain.
Compound
A basalt-based mineral slab that has undergone hydrophobic treatment, preventing moisture accumulation within the material.
Product Features
- Professional soundproofing;
- Quality control of each slab;
- Non-flammable material.

In sound-absorbing cladding and multilayer frame partition structures, the frame stud profile (or beam) is typically installed at 600 mm intervals. 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.
