Shumostop-K2

The high sound insulation properties of the SHUMOSTOP board system (ΔLn,w = 38 dB) for almost any floor structure provide an impact noise level 20 dB lower than the requirements of building codes. This provides for real acoustic comfort, when the sound of a bottle falling on the floor in the room upstairs is perceived in the room below as the fall of a light coin. Request Price

Overview
Specifications

Shumostop-K2 is a soundproofing mineral board with a high impact noise reduction index (34 dB) and a specific weight of 105 kg/m3. The use of the material in floor soundproofing provides increased acoustic comfort in houses with reinforced concrete intermediate floors. Effective operation in a wide dynamic and frequency range allows to consider the technical properties of Shumostop-K2 to be the best in the category of floor soundproofing products.

Applications

Shumostop K-2 is used to separate floating screeds from vertical surfaces, as an elastic layer along the perimeter of the room and in the locations of expansion joints to protect screed against shrinkage if the load on the floor is uneven. SHUMOSTOP-K2 boards are used for sound insulation in floating floor structures, both as the main elastic layer and in combination with Shumostop-S2 boards.

Composition

Basalt fiber treated with a hydrophobic compound.
