CALLA Discontinued

Calla is the perfect curtain for environments where acoustics are a challenge. Its top-class sound absorption makes it easy to create calm, harmonious environments even in large, open spaces, areas with large expanses of glass or high ceilings, or in other challenging spaces. Calla effectively dampens noise while the woven fabric’s soft drop ensures beautiful hanging. The colour range consists of 10 timeless colour variations based on natural, grey and beige.
