Overview

The Durisol Aluminum MASH TL-4 System is a lightweight, structure-mounted noise barrier system designed for bridges and elevated structures. Our system has been successfully tested under MASH (Manual for Assessing Safety Hardware) TL-4 conditions, proving its ability to stabilize a vehicle and reduce the severity of auto crashes.

While our Aluminum noise wall system is well-suited for a variety of applications, our MASH TL-4 crash-tested system was designed as a structure-mounted system for safer bridges.

NOISE REDUCTION

  • Built with perforations and a sound absorbing mineral wool interior, our panels are available in single or doubled-sided absorptive, and noise reflective options.

CRASH-TESTED

  • A barrier system proven to withstand MASH TL-4 impact loads.

PANEL RETENTION SYSTEM

  • Despite the severity of impact in the crash-test, the wall panels remained intact, and minimal damage was recorded.

Why us?

The Durisol Aluminum MASH TL-4 System is key to keeping our bridges and our drivers safe, while also reducing noise for the surrounding community.

Our design, engineering and project teams will work as an extension of your team to deliver industry-leading safety & noise protection.
