Wooden Grooved Panels

About the Product

Our Wooden Grooved Panels are a sophisticated solution for enhancing acoustic performance and aesthetic appeal in various spaces. These panels are crafted from high-density materials featuring grooves on the surface and perforated holes on the back side, creating a slit resonance absorption system. This design allows the panels to effectively manage sound across different frequencies, particularly excelling in the middle and low-frequency ranges.

The versatility of our grooved panels extends to their exceptional performance in absorbing medium and high frequencies. When paired with sound absorption cotton filled in the back side cavity, the panels deliver superior sound absorption, making them ideal for environments where acoustic clarity is paramount. Additionally, the design of these panels can be fully customized to meet your specific aesthetic and acoustic needs, ensuring a perfect fit for any space.

Available Finishes

Wooden grooved acoustic panels from Oakzone are available in three different finishes.

HPL

High Pressure Laminates (HPL) is a material that belongs to the high-tech group of high-pressure decorative laminates, compact laminates, and balance sheets, widely used as a surface finishes applied to different materials, such as MDF.

SPC/PVC

SPC/PVC is a rigid, high-density polymer overlay commonly used as a surface finish on acoustic panels. Smooth, moisture-resistant, and easy to maintain.

Veneer

Technical veneer is an economic solution to have a relative natural wood grain compare with melamine and HPL, it can solve the flaws from the natural veneer, such as color tone and scratch, but it can not be as natural as the real wood.

Core Materials

At Ecowood Panels, we utilize medium-density fiberboard (MDF) as a core material in our acoustic fabric panels due to its exceptional properties. MDF is crafted from recycled wood pieces pressed together with adhesive under high temperature and pressure, resulting in a dense and sturdy board. This material is stronger than particle board, offers a veneer finish that mimics solid wood, and is lightweight compared to hardwood. Additionally, MDF contains chemicals that repel termites and resists warping in humid conditions, making it a durable, low-maintenance, and cost-effective choice for various applications.

E2 MDF

Normal MDF without any special treatment, low cost for budget tight project.

E1 MDF

Eco-friendly MDF,
low formaldehyde emission,
density is higher.

E0 MDF

Imported MDF, super low formaldehyde emission, high density, cost is expensive.

B1 MDF

Fire retardant MDF, maximum fire rating can reach B1, weak against the humidity.

Black MDF

With both advantages of E1 and B1, high density and better against humidity.

Green MDF

Same as E1 MDF, but add agent to improve the ability against the humidity.

Installation Method

We can produce the microperforated acoustic panels for many kinds of installation situation, for both wall and ceiling. In both cases soft acoustic cotton and certain cavity are required for improving the optimal absorption coefficient.

Preparation Before Installation

Site Conditioning	The area must reach the required temperature and humidity at least 24 hours before installation.
Minimum Temperature	15 °C
Relative Humidity	40% – 60%
Acclimatisation	Open the cartons at least 48 hours before installation.
Keel Spacing	300 – 600 mm recommended

Install the wood keel or steel keel in accordance with the design drawing and construction drawing.
The keel configuration must match the configuration of the wood acoustic panel.
Fill fibreglass wool into the gaps between the keels as per the design.

Standard Method of Application

Note: This product is suitable for straight walls or flat ceilings only.

Steel Keel & Clips Method

Fix keel 001 to the wooden battens using gun nails and screws.
Insert clips 002 and 003 into keel 001, making sure the wood acoustic panel is securely held.
Install the panels from left to right and from bottom to top.
To adjust a panel's position, adjust the corresponding clips.

Steel keel and clips installation sequence

Installation sequence — keel, side-clip, acoustic wool, clip, acoustic panel.

Wooden Battens Method

Use wood battens to level the wall.
Fill in acoustic wool — thickness 25–100 mm, density 32 kg/m³ or 48 kg/m³.
Fix the panels to the wood battens using gun nails.

Level the wall with battens, fill with acoustic wool, then fix the panels.
