Designed by longtime collaborators, Architecture Research Office, ARO Block is a series of modular acoustic tiles that add sound control in a customizable, easy-to-install system. Available in several standard shapes inspired by geometry, spoke systems, and architectural shingles and cladding, ARO Block tiles are 3mm 100% Wool Design Felt mounted to an über-thin 10mm virgin PET acoustic substrate. 63 wool felt color options allow for endless con gurations and one-of-a-kind sound softening solutions that install wall-to-wall or in small areas to add color, texture, and unique patterning. ARO Block arose out of a need to resuse post-industrial remnant material at FilzFelt’s manufacturing facility. This material is generated from FilzFelt’s CNC cut products and projects and tends to be narrow strips that require smaller or modular products.
