Sub-framing Systems

Exo’s Horizontal Adjustable (HAF), Vertical Adjustable (VAF), and Floor-to-Floor (F2F) sub-framing systems offer advanced support for cladding materials like architectural high-density fiber cement panels, terracotta, UHPC, GFRC, stone, metal, and more. These systems are self-shimming and adjustable, allowing for quick, precise, and efficient installation. This feature is critical for ensuring level and plumb panel alignments, essential in both new constructions and recladding projects. Meeting NFPA 285 standards, our systems assure fire safety compliance. Customizable to project needs, they provide reliable, thermally isolated cladding support, optimizing energy efficiency and longevity of the facade. Our framing systems are designed to simplify installation while offering a versatile support structure for new construction or recladding projects.

HAF Sub-Framing System

The Horizontal Adjustable Sub-framing System (HAF) is a versatile, thermally isolated aluminum framing system that provides a reliable solution for modern building facades. This non-combustible system complies with NFPA 285 standards and is suited for both vertical panel framing and face fasteners, with an adaptable design for concealed hanging systems where necessary.
