15mm/ 20mm/ 25mm/ 35mm Acoustic Wood Wool Panel for Cement Sound Insulation System
The Acoustic Wood Wool Panel is a cement-bonded wood wool acoustic panel designed for professional sound insulation and absorption systems. These high-performance panels are manufactured from natural wood fibers (spruce or fir) mineralized and bonded with Portland cement, offering an optimal balance of acoustic performance, fire safety, and environmental sustainability for interior wall and ceiling applications. This multi-thickness series provides flexible solutions for projects requiring precise acoustic control — from basic reverberation reduction to Class A sound absorption.

Key Features and Benefits
1.Superior Acoustic Performance
The cement-bonded wood wool construction provides excellent sound absorption across low, mid, and high frequencies. Achieves NRC values from 0.60 to 0.95 depending on panel thickness, with optional acoustic infill achieving up to 1.0 NRC.
2.High Fire Safety Classification
Reaction to fire classified Euroclass B-s1,d0 or A2-s1,d0 in accordance with EN 13501. The non-combustible A2-s1,d0 variant provides enhanced fire protection for public buildings, corridors, and exit ways.
3.Exceptional Durability and Longevity
Service life of at least 50 years with virtually no maintenance required. The panels resist high humidity environments, rising damp, moisture, water, frost, and shock impacts, ensuring reliable performance in challenging interior conditions.
4.Environmentally Sustainable
Made from renewable wood fibers with FSC® and PEFC™ certifications ensuring responsible forestry practices. Low VOC emissions with formaldehyde E1 rating (no measurable emissions). Available with Cradle to Cradle Certified® and Indoor Air Climate certifications.
5.Thermal Insulation Properties
Declared thermal conductivity λD = 0.065 W/mK provides additional thermal insulation benefits, contributing to building energy efficiency. Thermal resistance varies by thickness from 0.20 m²K/W (15mm) to 0.50 m²K/W (35mm).
6.Aesthetic Design Flexibility
Available in natural wood, natural grey, white, black, and custom painted finishes. The natural texture creates a warm, organic aesthetic suitable for modern interior designs. Multiple panel sizes and edge profiles allow creative ceiling and wall pattern configurations.
