During design of a building and its envelope, the interfaces between different building materials are often overlooked. What happens when they come together? Documents often do not contain sufficient information to ensure the building envelope remains air- and water-tight, such as in regard to material, adhesion, compatibility and installation sequencing. When these problems are not addressed until after a building is under construction — or worse, when occupied — they will result in air, water and mold issues and even construction-defect claims.
This presentation will address the particularly important areas of window-wall transitions and the continuity of the air control layer at fenestration areas. Examples will identify what can go wrong, which will lead to five steps for developing details to improve the durability of both the façade and air barrier assembly. The presentation will cover UV durability, movement within a wall assembly, compatibility between building components, water resistance and durability at material interfaces. Participants are eligible for one AIA LU|HSW credit.
• Identify the 5 important elements of effective material interface details.
• Describe important attributes of detailing interfaces between building materials.
• Outline the process to develop and implement material interface details that meet predicted performance criteria in real life.
• Explain how compatibility and water resistance can impact a building façade assembly.
