The sound barrier series is divided into reinforced and non reinforced sound screen panels. In addition, reinforced panels are available in black and white, and various colors can be customized to meet customers' various requirements from multiple aspects.

Suggestion

Usage suggestions

1. Wind load

In the design phase of the sound screen project, the following factors should be fully considered

1. The situation on site, such as whether there will be strong winds (even occasionally)

2. Owners' technical requirements

3. Local relevant laws and regulations.

2. Fixed

According to current regulations and testing standards, acrylic sound screen panels should be fixed with appropriate frame surfaces, otherwise the sound screen panel may become excessively loose in strong winds, and in some extreme cases, may even detach from the frame.

Acrylic is a plastic polymer material. When selecting materials, it is necessary to choose acrylic sheets that are brand new and have relevant performance parameters that meet the requirements of the national standard GB/T 7134-2008. Otherwise, some performance and weather resistance cannot be guaranteed. Under normal usage conditions, the fading is not significant within three years (except for specially designated indoor color boards). The performance parameters of the new acrylic material are shown in the following table:
