Chomarat and AltusGroup presented the CarbonCast reinforced-concrete prefabricated wall panels, reinforced with Chomarat’s C-GRID carbon fibre grids, at The Future of Composites in Construction trade show in Chicago, US.
“Reducing installation time, improving the fire and safety performance, increasing the service life of structures, and cutting energy consumption are crucial criteria in the choice of a CarbonCast solution,” explains Altus’ Executive Director John Carson.
CarbonCast panels are classified ASHRAE 90.1. Thanks to the low thermal conductivity of carbon fibre, C-GRID reinforced panels are said to offer excellent thermal performance, providing uniform insulation, resulting in a comfortable, energy-efficient building.
The carbon grid developed by Chomarat replaces wire-mesh reinforcement. The company says the grid’s corrosion resistant properties make it possible to decrease the thickness of the concrete, rendering the prefabricated panels lighter in weight than standard prefabricated panels. This means that less cement and raw materials are required, and also less energy consumed to produce, transport and assemble the panels.
A recent project at the Martin Army Community Hospital in Greenville, South Carolina, US, involved the use of more than 18,600 m2 of prefabricated panels.
“The contractor decided on CarbonCast insulated panels, otherwise the hospital project could never have been finished on time with another system,” says John Leatham, Director of Sales and Marketing at Chomarat North America. “We take pride in the knowledge that C-GRID provides a durable, cost-effective solution for a large number of buildings in the United States.”
Since AltusGroup was established in 2004 more than 3.7 million m2 of C-GRID reinforced insulated wall panels, cylindrical piles and Double Tee components have been installed in 1200 different projects.
