Let us introduce you to the Nivelator Sound system. What is specific about it is that it preserves the room height as much as possible. The system offers a minimum density of 6 cm measured from the lowest point of each wall.
To perform the installation, the first step is wall preparation.
The next step is to lay out the structure and determine the placement of the profiles - lengthwise or on their short side. The distance between the profiles must be 50 cm and the distance between the hangers themselves must not go beyond the interval between 70 cm and 80 cm in relation to the width of the wall.
Once the structure is laid out, the location of the hangers is marked.
A Ø-6 drill is used to drill for 6 mm x 50 mm dowels, and the hangers themselves are inserted with 6 mm x 40 mm screws. The hangers allow a deflection of about 1 cm, but if a larger size is required, additional shims are fitted to level the system further.
The fourth step is to place acoustic separation tape along the walls. Its function is to separate the U-shaped profile from the walls.
Once the hangers are in place, the U-profile is inserted as well as the strapping tape, and the CW profiles are inserted using a "snap" technique.
These profiles are made specifically for the Nivelator Sound system and have a minimum thickness of 1.8 cm.
It is critical to pay attention to the leveling of the system. When placing it, it is necessary that the middle of the profile is exactly on axis through 50 cm. This will prevent the appearance of misalignment when the first layer of gypsophaser is placed.
After the construction is placed, the batting is placed.
In our case, it is 2 cm thick and is placed on the top of the profiles. In order to fill the air gap as much as possible, it is necessary to cut well around the hangers themselves. The distance between the batting and the board should be at a distance of exactly 1.5 cm to increase the air resistance.
After the placement of the wool, the next stage is the placement of gypsum fiber boards.
Their sizes range from 1.50 m x 1 m to 2 m x 1.20 m. They are always placed lengthways (their longer side) to match the structure.
After placing the gypsum phaser, all broken edges and joints are filled and fumigated with gypsum glue until a monolithic board is obtained. It will impede the passage of the sound wave.
After completion of this stage comes the penultimate stage - the placement of the membrane and plasterboard.
There are different techniques for placing them. In the case we have presented, the membrane is placed on the back of the gypsum board, then they are lifted together and clamped to the structure.
In order to avoid cracking and reinforce the strength of the wall, the gypsum plasterboard must be misaligned in the joints with the gypsophaser.
When we want to achieve a minimum thickness of the soundproofing wall, we use gypsum board with a thickness of 9.5 mm. It is fastened into the profiles of the structure with plasterboard screws measuring 3.9 mm x 35 mm. The membrane is clamped to the back of the gypsum board with a tacker, then the sheets are lifted and mounted directly onto the gypsum phaser, and clamped to the structure.
