Cementitious Wood Wool Acoustic Panels: Architectural Acoustic & Structural Solutions

Mineralized wood wool acoustic panels integrate natural pine wood fibers with white Portland cement binders under continuous high-pressure press processes. The open-cell porous structure mitigates sound reverberation across mid-to-high frequencies while providing structural impact resistance, thermal mass, and inherent moisture defense.

Engineered specifically for high-traffic and high-humidity spaces—including sports complexes, educational facilities, auditoriums, and parking structures—our panels carry verified Class A fire ratings, ball-impact safety certifications, and low-VOC emissions compliance for North American and European building codes.

Primary Architectural Applications

01/

Sports Arenas & Gymnasiums: Wall paneling capable of absorbing mechanical ball impacts without surface indentation or fiber breakage.

02/

Educational Buildings & Lecture Halls: Ceiling and perimeter wall installations engineered to shorten RT60 decay times and enhance speech transmission index (STI).

03/

Transportation & Underground Facilities: Ceilings in subway platforms, mechanical plant rooms, and parking structures requiring moisture-resistant thermal absorption.

04/

Commercial Offices & Public Atriums: Suspended ceiling tiles or direct-fix wall systems finished with custom RAL water-based acoustic paints.

Manufacturing Precision, Customization & Installation

Factory Customization Features
Color Coating Options: Factory-applied spray finishes using inorganic water-based vapor-permeable paints (Standard White, Natural Wood, Charcoal, or matched to RAL/NCS color codes).

Edge Profile Machining: Square Edge (SE), Beveled Edge (AK - 2mm/5mm chamfer), Rebated Edge (VK), and Tongue & Groove (TG - engineered for seamless interlocking and hiding installation screw heads).

Density & Core Tuning: Custom cement-to-fiber ratios engineered for enhanced structural rigidity or lighter handling weight per project submittal.

Field Installation Methods
Direct Screw Fastening: Secure panels directly onto light-gauge steel studs or timber battens using self-tapping masonry screws with color-matched painted heads.
Suspended T-Grid Systems: Drop 15mm or 20mm square-edge/rebated tiles into standard 24mm or 15mm exposed ceiling T-bars.
Cavity Insulated Assembly: Mount 25mm wood wool panels over a 45mm metal stud cavity packed with 40-60 kg/m3 rockwool insulation to maximize bass frequency sound absorption.

Quality Control & Compliance Protocols

Every production run undergoes mechanized fiber drying, automated weighing, press curing, and continuous inline dimensional monitoring.

[Debarking & Precision Shredding] -> [Mineralization & Cement Slurry Mixing] -> [Continuous Hydraulic Pressing (65C - 80C)] -> [Controlled Chamber Curing (14 Days)] -> [Edge Milling & Spray Painting] -> [Pallet Packaging]

Fiber Mineralization Control: Raw wood fibers are treated with sodium silicate and calcium chloride prior to cement mixing, turning the wood cellulose non-combustible and immune to rot.

Curing & Moisture Stabilization: Panels undergo a 14-day controlled humidity curing process to bring internal moisture content below 10%, preventing shrinkage or bow after installation.

Batch Testing: Structural flexural strength (EN 12089) and dimensional squareness checks are performed on 1 out of every 100 panels off the milling line.

Packaging, Minimum Order Quantities & Project Supply

FAQ

Q: How does the choice of binder (White Portland Cement vs. Magnesite) affect panel performance?

A: White Portland cement binders offer superior moisture resistance, higher structural compression strength, and enhanced dimensional stability in humid environments like indoor pools or semi-exposed soffits. Magnesite binders provide a slightly lighter weight and smoother surface texture, suitable for standard climate-controlled interior office spaces.

Q: What NRC rating can be achieved in a typical wall installation?

A: A 25mm thick wood wool panel direct-mounted to a solid wall yields an NRC of approximately 0.65. When installed over a 50mm air cavity filled with 40 kg/m3 mineral wool insulation, the sound absorption coefficient increases to NRC 0.85 - 0.90, heavily absorbing mid and low frequencies.

Q: Do these panels shed wood fibers or generate dust over time?

A: No. The factory mineralization process coats every individual pine fiber in a cement matrix. This prevents fiber fraying, flaking, or dusting during handling, installation, or long-term operational air movement.

Q: Can wood wool panels be installed in high-humidity areas like indoor swimming pools?

A: Yes. Because the pine fibers are fully encapsulated in mineralized cement, the panels do not absorb atmospheric moisture, warp, or support mold growth (tested under ASTM C1338). For pool environments, use stainless steel fasteners and hot-dip galvanized steel framing.

Q: Are factory-painted panels acoustically compromised compared to natural finish panels?

A: No. We apply low-viscosity, water-based inorganic acoustic paint using automated atomized spray nozzles. This ensures the color coats the fiber surfaces without clogging the open air voids essential for sound absorption.

Q: What certifications are supplied for building permit approvals?

A: We supply complete third-party laboratory test reports including ASTM E84 (Class A Fire Rating), EN 13501-1 (Class B-s1, d0), ASTM C423 / ISO 354 (Acoustics), and EN 13964 Annex D (Ball Impact Resistance).
