Description
The proline is a large-format, micro-perforated acoustic panel in real-wood veneer or CPL. At viewing distance the perforation recedes strongly and the panel reads as a calm wood surface. It is mounted over a mineral wool insulation layer, optionally with an additional open cavity for greater depth of effect. The classic perforation is the coarser of the two perforation patterns. At close range it is visible as a fine dot grid and has the larger open area of the line.
