Envirocoustic Wood Wool Lay-In Ceiling Tiles

Envirocoustic™ Wood Wool Lay-In ceiling tiles lead the acoustical-panel products category as an eco-friendly, high-performing, and cost-effective sound absorber that manages echo and reverberation to improve the acoustics in a room or space. Ecologically, Envirocoustic Wood Wool is simple to produce with three natural ingredients: wood fiber, water and Portland cement. Envirocoustic Wood Wool Lay-In ceiling tiles are Class A fire-rated and pass the NFPA 286 fire test. In addition, they meet the California Department of Public Health VOC emissions standards, making them eligible for LEED credits. The tiles are also highly resistant to microbial and fungal growth, and they are an optimal choice for a variety of public or private spaces. Standard-sized Lay-In ceiling tiles have quick lead times and can be installed easily by dropping them into a standard 15/16” H.D. T-Grid. With a state-of-the-art manufacturing process, Envirocoustic Wood Wool Lay-In ceiling tiles are manufactured with even thicknesses, consistent dimensions, and clean, square edges.

The economical Envirocoustic Wood Wool Lay-In ceiling tiles not only liven up a room’s aesthetics with design variety and visual interest, but they can also be paired with a cellulose acoustical backer to improve the tiles’ acoustical performance.
