32 3540 - Sound Walls / Noise Barriers


Plywall

Hoover Treated Wood Products  Specs
PLYWALL is the only pre-engineered, ASTM E-90 tested, pressure treated, kiln dried, all wood sound barrier on the market. Post and panel construction insures easy low-impact site construction and no concrete footings, and the warm look of wood provides curb appeal not offered by other rated barriers. Extreme heights and wind loading can be accommodated.


Smith Midland

Smith-Midland Corp. (Mid-Atlantic, Carolinas only)
In 1980 Smith-Midland pioneered precast concrete sound wall. Proprietary products, Sierra Wall and SoftSound set the standard. Sierra Wall was the first one-piece precast concrete supporting column and panel sound wall system. Now, SoftSound sound absorptive technology surpasses any other combination of durability, acoustics, thermal, strength and moldability. Available for highway, commercial or residential applications.
