Description

SmartPerf® is a micro-perforated acoustic panel with an aPerf® polyester core and a surface lamination that appears smooth and closed when viewed from a normal distance. It comes in three versions: oak decor foil and real oak veneer, each on one face, and a thicker white PET version finished on both faces. The wipeable surface makes the panels suitable for hygiene-sensitive rooms as well. They mount on walls and ceilings, directly or with an air cavity and optional bass trap inserts.
