Riga Wood Birch Plywood Perforated / Grooved Acoustic Panels

Perforated or grooved Riga Wood acoustic panels for walls, ceilings, furniture, and shopfitting absorb noise, helping to create a healthier and more pleasant environment.

Riga Wood birch throughout plywood Riga Decor, Riga Lacquer, Riga Mel and Riga Ply are recommended as base panels that can be customized according to project specifications.

Features and benefits:

• Absorbs noise and echo.
• Decorative appearance with a wide range of high-quality surfaces.
• Aesthetic and visually attractive.
• Ready to use, easily workable.
• Low volatile organic compounds (VOC), including formaldehyde emissions.
• Sustainable product.

Machining and treatment for grooved panels:

Panels are mechanically processed by grooving with a distance of 16 mm and width 4 mm on the decorative face of the panel, and with a distance of 16, 32 or 64 mm on the reverse face of the panel. Acoustic panels can be further machined and treated according to customer’s requirements: T&G, cut-to-size, CNC, milled, lacquered. Nonwoven fabric can be glued on the reverse face of the panel.

Machining and treatment for perforated panels:

Perforation with a distance of 16 mm or 32 mm.

Perforation diameter: 5, 8, 10, 12 mm.

Acoustic panels can be further machined and treated according to customer’s requirements: T&G, cut-to-size, CNC, milled, lacquered. Nonwoven fabric can be glued on the reverse face of the panel.

Gluing classes:

Riga Wood birch plywood is glued with weather and boilproof phenol formaldehyde or lignin phenol formaldehyde resin adhesive according to EN 314 / Class 3 Exterior. Bonding with moisture-resistant low-emission melamineurea-formaldehyde resin according to EN 314 / Class 1 and BS 1203 / H1 is possible.

Formaldehyde emission:

Riga Wood birch plywood formaldehyde emission level is significantly below EN 13986 Class E1 and complies with EPA TSCA Title VI and CARB Phase 2. Riga Ply is also compliant with the requirements of the Finnish Emission Classification of Building Materials (M1), French VOC Emissions Labelling Class A+ and Japanese 4-Star Regulation.

Testing report:

The measurements of the plywood panel sound absorption coefficient are made in cooperation with acoustics laboratory ”R&D akustika” according to EN ISO 11654. The following test results are shown for uncoated panels.
