Materials That Perform: Thermaflow®: thermal fill

Discover its Benefits

Optimized design.
Predictable thermal performance may allow contractors to optimize the design of the conduit capacity and trench depth, as well as reduce construction cost.

Reduce time and materials.
This material may allow a trench to be shallower and potentially require fewer runs of conduit. This can mean cost savings on excavation, as well as on the most expensive elements, conduit and cable.

Predictable, reliable performance.
Our team of experts have designed and pre-tested local mixes, so you can be confident the material will perform when you need it, where you need it.

Achieve More Efficient Design, Reduce Construction Cost  

Data Centers and high-demand electrical facilities must be fully operational 24 hours per day, 7 days per week and 365 days per year.

Thermaflow thermal fill is an innovative material that dissipates heat generated by buried cables that supply constant electrical power.
