Brand: Chova
Model: Multilayer partition wall system with a simplified structure of 54,7dBA
Type: Soundproofing partition wall
Description:
Multilayer partition wall made of two layers of dry plasterboard x 13mm and a viscoelastic layer of high viscosity membrane ViscoLAM 65 (4mm) 6.5kg / m² between the layers fastened on each side with a simplified structure of stainless steel profiles of 48mm width, with fasteners (vertical fasteners / 600mm spacing between them) and channels (horizontal elements).
The system is made with ChovANAPA 4cm PANEL 600 (acoustic polyester nappa absorbent material) placed between the fasteners.
Elements:
Plasterboard (13mm)
ViscoLAM 65 (4mm)
(air noise membrane)
3.Gypsum board (13mm)
4.COVANAPA 4cm PANEL 600
5.Laser for Structural Insulators ELASTOBAND 50 (4mm)
Mass: 58kg / m²
Airborne noise index: 54.7dBA
Thermal insulation: 1.22 m² K / W
Installation:
1-Mount the metal structure of the partition wall according to the installation instructions of the plasterboard systems, with a distance of 600 mm between the fasteners. Before installing all channels of the perimeter, add the ELASTOBAND 50 strip to the metal profile.
2-Insert the ChovANAPA 4cm PANEL 600 Acoustic Absorbent Material between the fasteners.
3-Screw the first layer of 13mm plasterboard to the metal structure according to the installation instructions for plasterboard systems.
4-Fix the ViscoLAM membrane to the plasterboard using any of the following methods:
using metal screws with a washer
using clamps 8-10 or 12mm
by means of a contact adhesive
The membrane sheets are glued together side by side to the gypsum board covering its joints.
5. Place the second layer of 13mm plasterboard onto the VISCOLAM 65 and seal the joints between them, according to the installation instructions of the plasterboard systems.
Notes:
By contacting the partition wall with the facade walls:
The outside of the façade wall must be interrupted, and the inner layer should not, in any case, close the vertical separation.
In order to avoid a reduction in the efficiency of the noise insulation during the installation, it is necessary to:
To avoid coinciding with the boxes of the installations on both sides of the partition wall.
Apply and fit the panels adequately
Application: partition walls in offices, dwellings, shops, shopping centers, etc.
