Alpha Hci System
The Alpha Hci System serves as the Horizontal CI Sub-framing layer designed to address fire safety, engineering and thermal performance. Based on panel layout, creates an attachment plane for horizontal panel layout.
ECO Cladding attachment systems incorporate intermittent Alpha brackets with continuous outer aluminum rails to create the “CI Sub-framing” layer. The exterior “Panel Sub-framing” is attached to this rail to create a complete rainscreen system.
Morrison Hershfield, an industry leader in thermal modeling, has analyzed the Alpha Hci configuration on steel stud walls with “CI Sub-framing” on two wall types: split insulation and exterior only cavity insulation. Using the ECO Calculator, the Alpha Bracket and Sub-framing layout can be determined and the corresponding wall’s U Value can be provided.
