Description
aPerf® panel colour, formerly aPerf board colour, is the design variant of the aPerf® panel: an anthracite polyester fleece core with a through-dyed lamination on one face, in eleven colors. It is meant for strongly colored wall and ceiling designs that make the acoustic treatment a visible design element. The panels are mechanically fixed, either directly or with an air cavity, and can be combined with bass trap inserts behind them.
