Brand: ChovA
Model: ChovaNAPA 4cm
Type: Polyester panel
Note: The price is for one m² !!!
Description:This is an acoustically absorbing material made of polyester fibers, ideal for soundproofing walls or ceilings. Sound absorbing materials are used to block the sound transmission path by absorbing noise as it comes into contact with the material. Instead of going back, as is often the case with harder materials, the sound can be absorbed by ChovaNapa, a soundproofing material specifically designed for walls and ceilings. The noise insulation panel has a high noise absorption coefficient and a very good thermo-isolator. Low flammable - does not contribute to fire, harmless material, dust-resistant, pleasant to touch, non-toxic, recyclable, without loss of fiber. It is not rubbed or spoiled and does not lose weight in deterioration. Quick and easy to install.

Installation:
Partition walls
For preformed planking
Place ChovANAPA between the lamellae of the laminated plasterboard system using the modulation to choose the right width. If using the ChovANAPA® ROLL form, use a cutter to cut the material
Ceilings
Place ChovANAPA on the laminated gypsum board. For these applications, with a dense size of 20 cm, we recommend filling at least 75% of the distance between the suspended ceiling and the structural floor.
STORAGE: The material should be stored indoors - away from bad weather conditions.
Application:
Filling of air chambers in dry lining systems and suspended acoustic ceilings, partition walls for thermal and acoustic insulation.
Acoustic air conditioning systems mounted behind perforated gypsum slabs.
Thermal insulation in facing facade systems.
Addition of soundproofing (absorbing treatment) in walls and suspended ceilings made of plasterboard.
