An in-depth look at the environmental separators for the roof, wall and below grade assemblies in regards to water control, air leakage control, thermal performance and vapor control.

Critical details that typically cause building performance related issues will be focused on the two largest failures of building enclosures: roof to wall connections and wall to window connections specific to curtain wall systems. A step by step look at each critical detail in regards to sequence of construction and the various connections to ensure airtight/watertight and thermally protected details. Real life photos and job conditions will bring the realities of the construction process to show typical errors found and how they can be addressed correctly.

Learning Objectives:

1. Articulate how transitions impact building enclosure performance through real life experiences in regards to energy loss, building performance and the sustainability of the system.
2. Correctly identify and prioritize critical details during the construction document phase to ensure an integrated approach is taken to heat, air, water and vapor control.
3. Assess each detail in regards to impacts of the 4 control layers and understand the various options for designing details for a variety of roof, wall and window assemblies.
4. Through the use of real-life case studies and photos, plan out the proper sequence of construction and identify quality control methods in construction document review to provide corrective action.
