Panel Cutaway
CarbonCast High Performance Insulated Wall Panels are self-supporting units featuring edge-to-edge continuous insulation (ci) as defined by ASHRAE 90.1. CarbonCast panels provide steady-state R-values of up to R-30 and higher per design. Used in loadbearing and non-loadbearing conditions, the panels are intended for vertical and also horizontal placement. Panel thicknesses can vary from 7" to 12".

Options

Varying thicknesses – interior wythes are typically 2" thick; exterior wythes are typically 3” 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.
