CarbonCast® Insulated Architectural Cladding

CarbonCast® Insulated Architectural Cladding

CarbonCast Insulated Architectural Cladding panels feature edge-to-edge continuous insulation (ci) as defined by ASHRAE 90.1, providing steady-state R-values of R-8 and higher per design. A non-loadbearing spandrel or column cover, the panels are intended for horizontal and vertical placement. Panel thicknesses can vary from 8"–12".

-Precast Advantages

-Precast Concrete Projects

Overview

• Continuous insulation to meet ASHRAE requirements
• Up to 40% lighter; enables reduced superstructure and foundation
• Reduced project carbon footprint
• Aesthetic flexibility
• Produced under license from AltusGroup, Inc.

Applications

The panels can be stacked for low- and mid-rise applications.

Options

Varying thicknesses – interior and exterior wythes are typically 1-3/4” thick. The exterior wythe can be thickened to accommodate architectural details.

R-values – insulation thickness can be increased to meet higher R-value demands.

Insulation types – typically expanded polystyrene (EPS, white in color); extruded polystyrene (XPS, blue or pink in color) also available.

Shapes – an assortment of architectural elements such as cornices, bullnoses and reveals can be cast into the concrete carefully and cost-efficiently.

Embedded finishes and veneers – stone, tile and thin brick can also be used as well as simulated limestone or granite.

Panel orientation – typical orientation will be horizontal; vertical orientation is possible.

Prefinished interior wythe – a steel-trowel treatment during manufacturing imparts a smooth, durable, surface ready for paint or wallcovering and ideal for applications like dormitories and apartments.
