We offer submittal packages for builders as well as professional installation.

Barrier Walls are normally used to place a sound barrier between a noise source and a sensitive receiver. This barrier creates a "sound shadow" zone of quiet that can be tailored to cover almost any size area either indoors or out. Absorptive noise control barriers provide maximum noise reduction with lightweight modular panels and/or louvers.

Our design services include layout, structural steel support framework, foundation design (for ground level barriers), access doors, sound control louvers and certified calculations including P.E. or S.E. stamp. Perfect for new construction or retrofit to an existing structure.
