Metal sound barrier
Anping Shengyang Metal Wire Mesh Products Co.,Ltd is metal sound barrier manufacturer.
Metal sound barrier
For the ultimate in Acoustic performance!!
These metal sound barrier are designed, manufactured & tested all in house to our rigid engineering and quality standards.Environmentally sound as the absorption core is made from recycled PET plastic.
Metal sound barrier composition: perforated outer skin with a ploymax internal panel core material, sold rear face,H post.
The outer metal skin has a nominal Rw rating of 26 to 28 which may increase slightly with the inner perforated lining and the insulation material.
The 23% open perforated metal facing as detailed below is unlikely to significantly degrade the Polymax core performance and hence sound barrier provides a high level of sound absorption (estimated at 0.90 or greater).
The overall wall rating is hence calculated to be Rw 28 to 30 with an NRC rating of 0.9 to 1.0.
