Celenit Panels vs Our Wood Wool Panels | Acoustic Performance & Custom Options

Celenit panels are well-known European wood wool cement acoustic boards, constructed from mineralized fir wood wool bonded with Portland cement. Thanks to its distinctive interwoven fibrous texture, reliable fire rating, breathable structure and excellent sound absorption, Celenit wood wool panels have become a top selection for architectural interior acoustic finishing across Europe for decades.

YUEFA Acoustic is a professional wood wool panels manufacturer. We produce high-quality wood wool cement panels with the same core material principle and comparable technical performance as Celenit panels. Our wood wool acoustic boards are engineered for wall cladding, suspended ceilings, gymnasiums, classrooms, auditoriums, offices and public spaces, delivering balanced acoustic control, durability and natural aesthetic.

What Is Celenit Wood Wool Panel?

Celenit panels belong to the wood wool cement board family. Raw materials are sustainable spruce/fir wood wool, mineralised and bonded with white or grey Portland cement plus mineral fillers. The open

Direct screw fixing is one of the most widely adopted mechanical installation methods for YUEFA Acoustic wood wool cement panels. This fixing technique is also commonly used for Celenit panels, delivering robust, long-term stability on solid masonry walls, concrete substrates or timber batten framing. It is preferred for projects where fast installation, reliable load bearing and easy on-site inspection are required.

This method directly fastens panels onto the substrate with corrosion-resistant screws. No hidden metal clips are mandatory, though screw heads can be blended with matching wood wool cement filler to achieve a seamless, clean visual finish.

Pre-Installation Requirements

1. Substrate CheckThe base wall or ceiling must be flat, dry, structurally stable and load-bearing. Timber battens should be levelled and securely fixed to the main structure if used as supporting framework. Remove dust, loose debris and contaminants before panel mounting.

2. Panel PreparationYUEFA Acoustic wood wool cement panels are rigid but fibrous. Pre-drilling holes is strongly recommended near panel edges to prevent cracking during screw tightening. Select drill bit size according to screw diameter.

3. Material SelectionUse hot-dip galvanised or stainless steel screws to avoid rust stains on the porous wood wool surface. Screw length must be enough to penetrate fully through the panel and gain sufficient anchorage inside battens or solid substrate.

Step-by-step Installation Procedure

1. Mark out panel layout, joint lines and screw fixing positions on the substrate. Keep consistent joint gaps across the whole surface for uniform appearance.

2. Pre-drill fixing holes on the YUEFA Acoustic wood wool panels at marked locations.

3. Position the panel in place and insert corrosion-resistant screws.

4. Tighten screws carefully with controlled torque. Do not over-tighten. Excessive pressure will crush the interwoven wood wool fibres, damage the panel surface and reduce fixing strength.

5. Follow the specified screw spacing: place fixings around panel perimeter and add intermediate screws for larger panels to avoid bowing or vibration movement.

6. After all panels are secured, check alignment and joint uniformity.

7. (Optional finishing step) Fill exposed screw heads with matching wood wool cement putty supplied by YUEFA Acoustic, sand gently once cured to create an invisible surface effect.

Key Technical Notes

• Screw spacing and screw type shall comply with project specification and YUEFA Acoustic installation datasheet.

• Maintain minimum edge distance from panel borders to prevent edge splitting.

• This direct screw fixing system works for both wall cladding and ceiling installation. For overhead ceiling application, substrate load capacity must be verified by structural engineer.

• For high-humidity environments, stainless steel fasteners are mandatory.

Advantages of Direct Screw Fixing

• Simple installation workflow, easy for contractors to learn and execute

• High mechanical holding strength and stable performance over decades

• Visible fixings allow simple inspection and maintenance

• Compatible with all YUEFA Acoustic wood wool panel thicknesses and fibre grades

• Same fixing principle as used for classic Celenit wood wool cement panels

Limitations & Warnings

• Over-tightening screws is the most common on-site mistake and will permanently damage the wood wool panel.

• Direct screw fixing is only permitted on adequate load-bearing substrates. Do not install onto weak, crumbling or unstable surfaces.

• Custom colours and finished surfaces require extra care during drilling and screwing to avoid surface scratches.

Technical Support

YUEFA Acoustic provides full installation documentation, screw recommendation tables and fixing spacing diagrams for direct screw fixing. We can also supply matching filler material and sample panels for pre-installation testing on site.

Application Scenarios

Just like Celenit panels, wood wool cement panels from YUEFA Acoustic are widely used in:

• School classrooms, lecture halls, libraries

• Sports gymnasium, indoor sports courts (high impact resistance)

• Office open-plan spaces, meeting rooms

• Auditoriums, recording studios, churches

• Shopping malls, public corridors, museum interiors

• Passive house and sustainable green building projects
