SYSTEMS/METAL BUILDINGS
Insulated panels are sometimes fabricated in the factory for field construction, providing good
quality control over the panels. In these systems, the joints between the panels become critical to
thermal performance. Figure 4.6.3 shows a joint detail with poor performance due to the fact that it
interrupts the continuity of the insulation system (Steven Winter Associates). The alternate design
contains an improved joint design with improved continuity of the insulation system.
