Saddle Up! Integrating Control Layers at Parapet to Rise Walls Conditions
Water, air leakage, deterioration and biological growth often occur at parapet terminations where adjacent rise walls lack proper integration of air and moisture control layers. These issues typically stem from missing or inadequate detailing, sequencing, trade coordination and installation, compounded by limited industry standards and a general lack of awareness. While most designs rely on two dimensional details, complex roof to wall interfaces require multi step, three dimensional detailing. Proper construction sequencing, trade coordination and mock ups, including saddle flashing, are essential. This presentation will review design principles for integrating control layers at complex conditions and demonstrate how freehand sketches, paper folding, 3D modeling, collaboration with trades and manufacturers and mock ups help develop effective saddle flashing details.
Learning Objectives:
- Understand the importance of critical detailing of control layers at complex conditions to avoid air and water related problems
- Learn effective ways to develop and design successful details at complex conditions that are constructable and durable
- Recognize the importance of considering construction sequencing and trade coordination when developing complex details
- Understand the importance of mock ups for evaluating detailing, sequencing and performance testing to ensure water resistant and airtight designs
