Description

Shumanet-BM is a non-combustible (KM0 fire safety class according to Federal Law of the Russian Federation №123) basalt-based sound absorbing mineral slab, manufactured using advanced technology at the production facilities of the Acoustic Group Company. Low specific weight (47 kg/cu.m) provides minimum load on the supporting structure and the assembly without the use of special devices.

You can find out the prices of Shumanet BM and other products of the Company in the full price list.

Application Area

The material is designed to fill the cavities between the supporting structures and linings made of sheet materials during installation of frame structures in residential and industrial premises. The high technical sound absorption performance of Shumanet-BM allows for achieving effective sound insulation levels of structures with a minimum increase in their weight.

Composition

Basalt-based mineral slab, hydrophobically treated, eliminating moisture accumulation inside the material.

Distinctive Features

  • Professional soundproofing;
  • Quality control of each slab;
  • Non-combustible (KM0 fire safety class according to Federal Law of the Russian Federation №123).

Installation
In the structure of sound-absorbing linings and multilayer frame partitions, the vertical profile (or beams) of the frame is mounted, as a rule, with a pitch of 600 mm. SHUMANET-BM slabs are laid in lathwork cells.
In the structures of acoustic suspended ceilings, the slabs are mounted in the space between the suspended ceiling and the floor slab. SHUMANET-BM is laid over the suspended ceiling or mounted to the floor slabs using plastic “mushrooms” for fixing heat-insulating slabs.
When used in unsealed structures, to prevent the emission of particles of SHUMANET-BM slab material into the environment, it is recommended to wrap it with sound-permeable non-woven cloth such as spunbond.
