With noise being a prominent problem in most people’s day-to-day lives, it’s important to take steps to reduce the negative impact that it can have – this can be done using our acoustic wooden panels. By installing MuffleTimber, you can dampen excess noise within the space whilst positively impacting your interior design.


None of our acoustic wood panels contain any harmful chemicals or materials. We always source high-quality products that are gentle on the environment, and on your health and wellbeing and these slatted panels are no exception.

The base of the product consists of a 9mm thick black or gray polyester material which is obtained from a plastic recycling process. The material is certified in accordance with the requirements of Global Recycle Standards and does not contain substances harmful to health (e.g., formaldehyde, pentachlorophenol).

Dimensions (Inches): 96" x 23.75"

The decorative wooden slats consist of 13mm thick MDF / Plywood strips which are finished with veneer. These slats are 96” x 0.97” wide and 15mm apart.

The acoustic wood panels are easy to trim down if required to better fit the space.

The maximum tolerance in the panel dimensions is +/- 1mm.


The panels are installed using screws which makes installation fast, simple, and suitable for amateurs. For installations aiming to align slats end-to-end seamlessly, we highly recommend maintaining a 3-5mm shadow gap, whether for walls or ceilings.

Images are for illustrative purposes only. Due to the nature of wood veneer, colors may vary slightly but if you want a more accurate look at your color choice you can order a MuffleTimber Sample.
