— WHAT IS WOOD WOOL —
Long wood fibres, bonded by cement
Wood wool acoustic panels are made by binding long, fine wood fibres (slivers of spruce or fir) with an inorganic cement or magnesite binder. The open, textured surface absorbs sound while the cement gives the panel structural integrity and natural fire resistance.
— ACOUSTIC PERFORMANCE DEPENDS ON INSTALLATION —
Three mounting methods · three performance tiers
The same wood wool panel can deliver very different acoustic results depending on how it's mounted. Choose the method that matches your room's volume, frequency target, and budget.
Panel fixed directly to wall or ceiling — no cavity, no backing.
Best for: corridors, decorative walls, general echo control.
Panel installed on battens or suspended with a cavity behind. Cavity depth tunes low/mid-frequency absorption.
Best for: offices, classrooms, restaurants.
Panel installed with 30–75 mm acoustic stone wool behind. Highest absorption tier — subject to tested system.
Best for: mosques, theatres, halls, high-performance spaces.
⚠ Final acoustic performance depends on panel thickness, fibre width, air-gap depth, backing material, installed area, and room volume. Always confirm against the selected supplier's tested-system report and project-specific acoustic submittal.
— CHOOSE YOUR SHAPE —
Eight standard shapes · wall and ceiling
— COLOUR & FINISH OPTIONS —
12 standard colours · RAL / NCS on request
All twelve standard colours are pigmented through the fibre — not surface-painted. Custom RAL or NCS colours are available for project orders, subject to minimum order quantity and approval sample.

— INSTALLATION METHODS —
Four supported installation systems
Adhesive or mechanical fixing on a flat substrate (plaster, concrete, drywall). Fastest method · no cavity · baseline acoustic performance.
Panels fixed to timber or metal battens with a 25–75 mm cavity. Improves low/mid-frequency absorption and allows a service cavity for cables and conduit.
Drop-in tiles on a standard 600 × 600 mm or 600 × 1200 mm T-grid. Easy access to plenum services · ideal for offices, schools, public interiors.
Premium architectural finish — grid hidden inside panel rebates for a flush, continuous appearance. Available on select product families.
