Features:
Recyclable, environmentally friendly
Wood plastic composite (WPC) made of 100% recycle raw material.
Water-proof, termite-resistant, aging-resistant,
Wood plastic composite(WPC) can stand up to wind, rain and sun. Installation and operation is easy. It is widely used in places near water and moist environment: outdoor decking, bypath, pavilion, platform, wall decoration.
High Cost Performance
The primary input of WPC product is a little higher than common lumber, but because of less maintenance, anti-moth and long life time, it is a highly cost performance product.
Easy to install, minimal maintenance required
could be cut, drilled or nailed. Adjustable specification and shape, very flexible

Common Applications:
1.studios, recording rooms, listening rooms, rehearsal rooms and more professionally interspace timbre projects.
2.theaters, indoor gymnasiums, discos, KTV rooms and more performance and entertainment location.
3.meeting rooms, offices, halls, hotels and more sound absorption and secrecy projects.
4.air-port, railways, bus-stops, workshops and more noise reduction projects.

Perforated wall panels performances:
Acoustic absorption is usually defined in terms of an absorption coefficient(usually denoted by the Greek letter alpha, α), defined as the ratio of absorbed to incident sound energy from a single interaction between a sound wave and a certain material. Absorption coefficients range from 0 to 1 and vary with frequency, α=0 means that the material absorbs no sound and reflects all sound energy incident on it.
α=1 means that the material absorbs all sound energy incident on it and reflects none. Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb some sound. In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having absorption coefficients greater than 0.4 are considered to be absorptive.

As you can see our Testing report show that our products have a very good performance in a
large range of application.
