Tech Note B006-25: Introduction to Evaluation Services and Explanation of Evaluation Reports
$5.00
Reaffirmed in November 2025
Summary: Evaluation reports act as a bridge between authorities having jurisdiction (AHJs) and manufacturers in conveying specific information on building products and systems relative to compliance to codes and standards. When an evaluation report is made available and determined as supporting the product’s use in projects, approval of the code official should be solicited. After such approval is attained, the design and installation details given in the report need to be observed and the labeling of the actual product needs to match the description provided in the evaluation report.

CFSEI documents are not intended to exclude the use and implementation of any other design or construction technique.

Tech Note T202-20: Thermal Energy Transfer of Cold-Formed Steel Framing
Summary: While the concepts of energy conservation and efficiency are not new, the demand for sustainable building is at an all-time high. Energy efficiency, and more specifically thermal energy transfer in steel stud construction, presents the construction team with a clear opportunity for reduction in thermal bridging. Advanced analysis of building thermal simulation through scientific thermal modeling programs illustrates that the construction team has the ability to significantly reduce thermal transfer. Use of cold-formed steel framing with a reduced thermal bridging area, in combination with increased spacing of the framing system provides, among other benefits, a significant and positive impact on thermal performance.

Tech Note F100-23: Design of Clip Angle Bearing Stiffeners
Summary: Clip angles are commonly used in cold-formed steel constructions to attach floor joists to the rim track. Clip angles can also work as bearing stiffeners to reinforce the web crippling strength of the floor joists at the bearing locations. As the length of the clip angle may significantly influence the floor joist web crippling strength, it is critical to ensure the minimum length of the clip angle in design.
