FIRE RATED

Fire Separation Walls & Enclosures

An integral piece of the fire suppression and
control system at utility substations.

Contain and prevent the spread of fire.

Transformer fires are a leading cause of power outages and costly repairs. Trusted by power distribution providers across North America, our fire-rated barriers are engineered to contain fires, protect critical infrastructure, and reduce risk to surrounding communities.

Performance Features

Public Appeal

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

Wall Solutions for Every Architectural Style

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

Ease of Installation

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

Quieter Surroundings

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