The Kokowall® High Absorption acoustic barrier is for applications with high sound absorption requirements.
The outer layer of durable coconut fibre allows plants to grow on them and a Kokowall® screen is fully overgrown within a few years.
Key features
- Effective, highly absorbent, natural and attractive
- High sound insulation and sound absorption
- Available in range of heights and widths
- Climbing plants can grow on both sides
- Cost-effective
- Short construction time
- Certification: CE in accordance with EN14388: 2005 and GCW2012
Technical properties
- Sound absorption EN1793-1: Dla = 10dB (a) cat. A3 (with a layer of 30mm mineral wool)
- Sound absorption EN1793-1: Dla = 15dB (a) cat. A4 (with a layer of 40mm mineral wool)
- Sound insulation EN1793-2: Rw=30dB (a) Dlr=27dB (a) cat. B3
- Maximum construction height: 10m (through stacked panels)
- Panel weight: 23-30kg/m2
- Standard panel width: 3960mm (max 4960mm)
- Maximum panel height: 2000mm (with W=3960mm)
- Panel thickness: 13–14cm
- Foundation: vibratory driven foundation pile, onto which a lintel is mounted
- Material: version with coconut tube on both sides with in-between a layer of mineral wool
- Steel frame and posts version: galvanised or powder coated
