Perforation composed of micro-holes of 1.1 mm diameter, 6 mm pitch and 3 mm spacing. The sound wave penetrates the panel through the multitude of micro-holes (+/- 55,000 holes/sq.m) and is trapped in the MDF core, thus limiting its reverberation.
The 1.1W085 micro-perforation is available in the following Oberflex collections :
- Oberflex wood veneers - +70 references of real wood laminates
- Metal d'Oberflex - 5 Skin brushed aluminium (4041, 4042, 4045, 4049 and 4051)
- Pure Paper Color - 25 Skin extra mate colors
- Anti-fingerprint - 25 anti-fingerprint colors
Structure of the panel : Oberflex decorative surface (wood, solid color or metal) + 16 mm MDF substrate (natural or black) + balancing + black felt.
