Harder, Luckey & Hargrave Inc. manufactures two types of it's Tuf-Barrier™ noise abatement wall system. The "32 STC-Heavy Wall" system meets or exceeds AASHTO guidelines in the key mass requirement, wind load sustaining (most heights and velocities) and decibel reduction criteria. The more economical "25 STC-Medium Wall" system, while lighter, still provides exceptional sound reduction performance. Both systems are aesthetically pleasing, easy to install, remarkably rugged and virtually maintenance free.
Used in situations where AASHTO Guidelines do not need to be met but where an effective sight and sound barrier is needed. Suggested uses include subdivision perimeters, light commercial & residential noise barrier walls and loud equipment screening.
