Shumanet-ECO Acoustic Eco-Friendly Fiberglass Slab

The acoustic eco-friendly fiberglass slab Shumanet Eco is made of glass staple fiber. It features a high sound insulation performance. It is a non-combustible material (flammability category: non-combustible (KM0 fire safety class according to Federal Law of the Russian Federation №123)). It is used as a middle layer when building frame sound-absorbing wall and ceiling structures.

Description

Description

The description of Shumanet-ECO should start with its fundamental difference from other similar sound absorbers: the absence of bakelite resins in the composition and the use of synthetic binder elements that guarantee its environmental safety.

Application Area

The acoustic eco-friendly Shumanet-ECO slab is designed for use in sound insulating and sound-absorbing structures; it is laid in the space formed by the surfaces of the supporting structures, frame elements, and lining. The Shumanet-ECO technical parameters and environmental friendliness allow it to be used in any premises, including children’s institutions.

Composition

The staple fiberglass, that is used as the main component of the plate, is treated with a water-repellent compound. The acryl-based binder is an absolutely safe and non-toxic substance.

Given the properties of the slab, its environmental safety and the cost of Shumanet-ECO, you can understand its advantages in comparison with similar materials from other manufacturers:

  • Professional soundproofing;
  • An environmentally friendly product;
  • Non-combustible (KM0 fire safety class according to Federal Law of the Russian Federation №123).

Installation

SHUMANET-ECO slabs are laid inside the framework of a partition, lining, or suspended ceiling structure.
In the designs of acoustic suspended ceilings, the slabs are mounted in the space between the suspended ceiling and the floor slab.
The slabs can be mounted to the floor slabs using plastic “mushrooms” for attaching insulating slabs.
When used in unsealed structures, to prevent the emission of material particles into the environment of the slab, it is preliminary recommended to wrap it with a sound-permeable non-woven fabric such as “spunbond”.
Cotton gloves are recommended for hand protection when working with SHUMANET-ECO slabs.
