Environmental Noise Control, Inc. offers modular K-Rail mounted sound walls in various heights, built to fit your needs.
ENC’s patented K-Rail mounted sound walls can be quickly positioned and moved to provide a flexible noise control solution for mobile equipment or operations. ENC’s newly redesigned double K-Rail frame allows for heights up to 20 feet, depending on the site and environmental restrictions. These sound walls are an effective solution if your project does not allow earth boring.
At the heart of ENC’s free-standing noise control systems are ENC’s noise barrier blankets manufactured using state-of-the-art acoustical composite materials. They are available in STC-25 and STC-32 with NRC overlays.
An independent laboratory has tested ENC’s acoustical blanket materials.
Engineering/calc packages available.
