Installation:
1. The material should be clean and free from irregularities.
If the material is perforated, its acoustic performance will decrease.
2. Expand ChovAIMPACT 10 HIGH-STRENGTH
3.Enlarge the material by leaving an additional 10cm.
4.Place the ChovASEAL adhesive tape into the sealing contact areas.
5. Place the ChovAIMPACT strip on columns, outside walls, terraces and around
Any other element with the potential to create an acoustic bridge.6. Put a screed about 5 cm. On the designated insulation space.
Application:
- Protection against impact noise in buildings (houses, hotels, schools, offices, etc.).
- Protection against impact noise in rooms requiring high mechanical resistance
(Floating foundations for machines, car parks, etc.)
