Features & Benefits

Engineered fire-rated wall systems that contain transformer fires, reduce noise, protect critical power infrastructure, and integrate seamlessly into surrounding communities.

Performance Features

Panels come in a variety of architectural textures, patterns and colors that will fit in any neighborhood.

From standard precast concrete texture and pattern to more intricate cast custom panel work – we can match any neighborhood aesthetic.

Modular post and panel system as as easy to assemble as they are to disassemble during transformer repair and maintenance.

Alleviate noise concerns by reducing noise with reflective or absorptive noise attenuating panels.
