Webinar Details

Cold-formed steel (CFS) framing often requires use of exterior continuous insulation to achieve code-compliant thermal and moisture performance. But, how can we attach cladding and other exterior elements through a layer of rigid foam sheathing (a non-structural material) to CFS framing in a code-compliant manner? This presentation will provide a review of the research and code development that answers that question.

This presentation will explain the design methodology and the derivation of its “gap reduction factors” for typical screw fastener connections through up to 4-inches of foam sheathing to CFS framing members. A key feature of the design method is its ability to conservatively limit joint deflection for serviceability while maintaining or exceeding intended design capacity performance.

Prescriptive connection solutions included in the recent model building code editions also will be presented for routine attachment of furring and cladding materials through foam sheathing. In addition, application of the design methodology for lightly-loaded structural elements, like ledgers, will be discussed.

This presentation will help design practitioners and specifiers “bridge the gap” for connections to CFS wall assemblies that include an intervening layer of foam sheathing continuous insulation.

Learning Objectives

• Learn how research and test data were used to develop a connection design methodology and its “gap reduction factors”
• Understand how the connection design method controls both stiffness (serviceability) and strength (safety) by use of a deflection-limited performance objective
• Learn how to apply the design method and prescriptive connection tables in US model codes for connection of cladding, furring, and other elements to cold-formed steel framing through an intervening layer of rigid foam sheathing
• Gain knowledge of resources available to support design and specification as well as a standardized testing methodology to qualify alternative fastening solutions
