Sustainable Building Envelope Performance with Self-Sealing Fasteners & Anchors

1.0 IIBEC credit and 1.0 GBCI credit

Sustainable building envelopes demand high performance from and proper installation of continuous insulation and air, water, and vapor control layers. What happens when thousands of holes are made in these materials as they are installed with blind fasteners, one layer on top of another by different subcontractors? Sequencing issues can generally not be avoided; instead, this course focuses on self-sealing fasteners as a solution to avoid damage and thermal bridging in insulation and control layers. Various fasteners and anchors are described, and recommendations are presented for how to specify and what testing data to look for.

Learning Objectives:

1. Describe the functions of a wall and the air, water, vapor, and thermal control layers that are essential to sustainable, energy-efficient buildings without excessive moisture penetration.
2. Explain how fastener penetrations can cause damage and permit air and water leaks through control layers, resulting in diminished moisture management and energy efficiency of the building envelope.
3. Select fasteners and anchors capable of self-sealing to manage moisture, increase energy efficiency, and ensure sustainable thermal performance of the building envelope.
4. Discuss strategies to easily specify fasteners and anchors tested in complete wall assemblies, including cladding attachment solutions to ensure sustainable long-term building envelope performance.
