The PROCEEDR study has identified that traditional noise barrier wall materials can be carbon intensive, the market is challenged to move from a linear to a circular economy. Whisper NB is here to help system producers in their efforts. Interior absorption materials need elaborate protection systems to adapt to outdoor life. Whisper® NB is an innovative hydrophobic metamaterial designed from the polymer up, for the rigours of outdoor life. Eliminating the need for protective covers or moisture barriers while using a lower mass to attain similar acoustic outcomes.
Validated for a 50-year working life Whisper NB offers from 8, up to 12dB of absorption and 5-6dB in-situ reflection, passing impact and durability testing to EN 14388. The material was designed also for compatibility with re-use initiatives, post-industrial recycling systems for LDPE foam, and for energy recovery systems. Whisper NB-Eco Grey carries a Type III Ecolabel (EPD) and contains no hazardous substances or additives; NB-Eco Green credentials will be published in the near future.
This durable, recyclable solution allows producers to explore claddings and open-faced cassette designs with recycled materials. This can be seen absorbing noise in innovative new noise barrier walls from Hatko Sound Barrier, 4Silence, and Panacor.
