Frequently asked questions
What absorption class does OPTIC diamond achieve?
OPTIC diamond achieves sound absorption Class B with a weighted coefficient of 0.80 aw, measured to DIN EN ISO 354. This places it among the higher-performing fabrics in the Acunic range.
How does OPTIC diamond compare to the CUBIC range?
OPTIC diamond is thinner at 2.34 mm compared to 3.80 to 5.40 mm for the CUBIC variants, but achieves a higher absorption class (Class B, 0.80 aw) versus Class C (0.75 aw) for the CUBIC family. The OPTIC diamond surface is a faceted geometric relief rather than the raised cubic structure of the CUBIC products.
Is OPTIC diamond suitable for curtain applications?
Yes. OPTIC diamond is confirmed suitable for curtains as well as wall and ceiling elements, making it versatile for both panel-mounted and free-hanging acoustic treatments.
