High Concrete Group LLC has introduced ThinCastTM, the thinnest precast concrete rainscreen panel available on the market. Designed for use in commercial, institutional, retail, and low- to high-rise construction, this innovation provides architects with the natural beauty and character of concrete in lightweight panels that accomplish their rainscreen design goals.
Concrete insulated wall panels in typical thickness of 11" or greater, may be load-bearing or non-load-bearing. The sandwich design provides an insulated wall for thermal efficiency and moisture control. The completed insulated wall assembly meets the requirements of continuous insulation as defined by ASHRAE 90.1. Structural performance in load-bearing condition requires thick inner wythe. Reveals, articulation, decorative accents, mix design(s) available to meet design requirements.
Concrete insulated panels are a low-maintenance thermally efficient building envelope solution for low- and mid-rise applications. Insulated concrete is frequently chosen for offices, university buildings, hospitals and health care, apartments, condominiums, and dormitories, schools, warehouses, manufacturing, food processing, and clean rooms. Interior surfaces of the insulated wall panel are available with a paint-ready steel trowel finish to eliminate furring and drywall.
Concrete insulated wall panels provide non-composite performance and are non-structural without a thickened interior wythe to resist gravity loads. For applications that require thinner insulated walls with the same thermal and moisture performance, insulated wall panels that transfer shear forces between concrete wythes are available. By contrast, CarbonCast Insulated Wall Panels utilize C-GRID low-thermal conductivity carbon fiber shear trusses that supply 100 percent structurally composite performance.
Insulated concrete is recognized as a mass wall in the energy code. Thermal mass is the capacity of an insulated wall assembly to absorb large quantities of outside and inside heat and to release it slowly. This characteristic delays the onset of peak heating or cooling loads, reducing indoor temperature fluctuation to improve occupant comfort. The thermal mass effect may reduce peak demand/energy consumption and enable downsized HVAC systems.
Periodic inspection of caulk panel joints is required for the insulated wall to retain its design R-value and to protect the interior of the building from uncontrolled air infiltration and exfiltration and from moisture intrusion. Caulking for insulated wall panels is subject to renewal per caulk manufacturer specifications, typically every 10 to 15 years.
Insulated walls sandwich a layer of rigid insulating foam board, usually EPS or XPS closed cell foam, within two wythes of precast concrete. The inner and outer concrete wythes of the insulated wall are connected through the foam layer by low-thermal conductivity pins that are cast into the insulated wall panel during production. The pins allow the precast wall to be stripped from the form and resist wind loads after the panel is installed. Insulated walls are produced in accordance with PCI guidelines in a PCI-certified precast manufacturing facility.
