Product Description

Wood slat acoustic panel (also known as slatted acoustic panel) is a decorative sound-absorbing panel manufactured by arranging solid wood slats or MDF/WPC slats at uniform spacing over an acoustic felt backing (typically PET polyester fiber acoustic mat), bonded together through high-temperature and high-pressure lamination. The core sound absorption principle is that sound waves entering through the gaps between slats are absorbed by the porous fiber structure of the backing, where sound energy is converted into heat through friction and viscous resistance within the fiber pores, effectively reducing reverberation time and eliminating echo.

 

The typical structure consists of:

Slat Layer: Solid wood, MDF (Medium Density Fiberboard), or WPC (Wood-Plastic Composite) slats, finished with wood veneer, PVC film, or spray coating for decorative purposes

Acoustic Felt Backing:  High-density polyester fiber (PET) acoustic mat with a porous fiber structure, typically 8-12mm thick, which is the core of the sound absorption function

Gaps:  Uniform spacing between slats (typically 12-50mm), which determines the acoustic performance of the panel

 

The slats and backing are available in various colors to suit different interior design styles. The panels meet E0/ENF environmental standards and Class B1 fire rating. They are widely used in indoor spaces that require both acoustic optimization and aesthetic appeal.

Installation Methods

Wood slat acoustic panels are easy to install. Three methods are available based on wall conditions and application scenarios:

 

Installation Method

Description

Suitable Scenarios

Adhesive Mount (Direct Bonding)

Apply eco-friendly structural adhesive (MS adhesive, construction adhesive) evenly to the backing, then press onto flat walls. Drying time approx. 12 hours

Flat walls, small areas, fast installation

Screw Fixation (Direct Fixing)

Use self-tapping screws through the backing to fix panels to walls. Countersink screw heads into backing or use color-matched screws. 12-20 screws per panel

Drywall, wood walls, applications requiring strong fixation

Furring Strip Installation (Recommended)

First install wood or light steel furring strips (approx. 600mm spacing), then fix panels to strips with screws. The cavity between panel and wall can be filled with acoustic wool for enhanced sound absorption

Uneven walls, applications requiring higher acoustic performance, large areas

 

Installation Steps (Adhesive Mount):

Clean the wall surface—ensure dry, flat, and free of dust/oil

Mark layout lines on the wall according to design

Apply eco-friendly structural adhesive evenly on the backing (use a notched trowel or strip/dot method)

Press the panel onto the wall along layout lines, level with a spirit level

Join adjacent panels tightly, ensuring slats are aligned (slat alignment is critical for visual appeal)

Use temporary supports to hold for 12 hours until adhesive fully cures

 

Installation Steps (Furring Strip Installation - Recommended):

Mark guidelines on wall, install wood or light steel furring strips at 400-600mm spacing, level them

(Optional) Fill cavities between strips with fiberglass or rock wool to enhance sound absorption

Fix wood slat acoustic panels to furring strips with self-tapping screws through the backing

Ensure slats align when joining adjacent panels; seal panel joints with acoustic sealant

Finish edges with trim profiles or corner moldings

Clean the surface—installation complete

 

Important Notes:

Allow panels to acclimate in the room for 48 hours before installation to adapt to ambient temperature and humidity

Use a fine-tooth saw blade when cutting; cut the backing with a utility knife

For adhesive mount, ambient temperature should be above 5°C, humidity ≤85%

Slat alignment is critical for wood slat acoustic panels—use a spirit level frequently during installation
