Building high-end and affordable noise barriers to block traffic noise.


Highway to Silence.


Fancy sound absorber based on PC. A blend of recycled polycarbonates are injected into a high-tech mould, providing a UV-resistant and strong shell. The interior is equipped with a sound absorbing polyester mat is hydrophobic and made from recycled bottles, acoustic performance from 12dB(A) up to 19dB(A).
