Brand: Chova
Model: ChovAIMPACT 5
Type: soundproof polyethylene pad against impact and airborne noise
Description:
High quality polyethylene sheet produced by extrusion process, direct and physical expansion of closed and watertight cells that provide the exact consistency Good behavior to aging under continuous load.
Installation:
under a floating mortar
1.The surface must be clean and uneven. If the material is drilled, this will reduce its acoustic properties.
2. Unfold the envelope and apply ChovAMPACT 5. Place the next piece of material overlapping approximately 10 cm.
3. Place the ELASTOBAN 50 patches to overlap the joints and ensure tightening.
4. Place perimeter, bearing columns, barriers and all other elements susceptible to creating an acoustic bridge.
5. Make a 5 cm cement mortar.
The quality of this system also depends on the type of mortar that is selected.
under parquet:
1. Remove ChovAIMPACT
2. Place the next section of the material as a continuous process.
3. Place the parquet on the polyethylene sheet so that it does not touch the walls.
