Cold-formed Steel (CFS) Frame Above Grade Walls with Foam Plastic Insulating Sheathing – Continuous Insulation
This part of the Design Guide is based on use of foam plastic insulating sheathing continuous insulation (FPIS ci) on conventional or engineered CFS frame walls that comply with the locally applicable building code. It provides a methodical step-by-step design decision-making sequence to result in an efficient exterior CFS frame wall assembly with FPIS ci. FPIS ci is more than just insulation, it offers multi-functional capabilities to optimize wall performance.
The appropriate, code-compliant use of continuous insulation provides a means to meet or exceed energy code requirements while also protecting the building and its structure. From an initial concept to a finished detail, the steps shown below provide an aid for compliance with relevant building code requirements and best practices related to the application of FPIS-ci on exterior CFS frame walls.
