A completely integrated exterior wall assembly that provides extreme energy efficiency as well as air infiltration and moisture management.
The integrated Hybrid CI exterior wall assembly features an advanced light gauge steel panel, continuous exterior insulation, a water-resistive layer, and an air barrier in a single panel, providing an energy-efficient, moisture-managed wall solution with fewer materials and installation steps. It is a total solution that finally makes steel stud wall framing thermally efficient.
The Hybrid CI wall assembly provides a continuous thermal barrier that insulates both the wall cavity and steel studs, which transfer heat ten times faster than wood studs, and moves the dew point from within the wall cavity to the exterior where it belongs. Finished with closed cell foam insulation on the interior wall cavity, the system blocks air and moisture infiltration and meets fire code.
The complete Hybrid CI wall assembly offers a true high R-value and extremely high energy efficiency.
Continues Insulation (CI)
“CI” Defined ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) standard 90.1 defines continuous insulation (“ci”) as “insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope.”
Recent changes to the ASHRAE 90.1-2007 and 2009 IECC energy efficiency standards that make continuous insulation, or CI, a prescriptive requirement for above-grade steel-frame commercial construction.
The energy and atmosphere credit for LEED 3.0 now uses ASHRAE 90.1-2007 as its baseline, with credits ranging from 1 to 19
Legislation now before Congress pertaining to 2010 building codes will likely mandate a 30% reduction in energy consumption standards, using the baseline of ASHRAE 90.1-2004 and 2006 international energy conservation code.
