solid woodpinerectangular

Short description
Solid wood acoustic panel for suspended ceilings with standard T24 grid.

Overview

• The quickest and easiest system to install and remove.
• Easy to install by a single operator.
• Installation from below - patent pending: a patented system allows installation from below, without entering the plenum. The system allows the addition of standard acoustic tiles (not included); install insulation first, then attach the Laō tiles in one quick, simple movement.
• Removable panels for easy maintenance.
• Invisible frame: assembly conceals the framework and ensures perfect panel alignment. Installation is carried out on black T24 framing with a maximum load of 13.5 kg/m2, uniformly distributed in accordance with current standards and good practice rules for each country. Laudescher does not supply all structural elements.

Tile / mounting
1200 x 600 mm tile for T24 grid; for suspended ceilings with standard T24 grid at 1200 mm grid spacing.
