The roof to wall joints are one of the most challenging to seal in order to provide continuity throughout the building envelope. Connections must be compatible and sequenced appropriately to withstand maximum wind loads, building movement due to thermal, seismic, moisture content changes and creep. Air finds any way it can to travel through a building. Joints must be able to support the same air pressures as the air barrier material without displacement. Uncontrolled air pressure across the building envelope and within the building itself can cause infiltration and exfiltration that overpower HVAC systems and can result in occupant discomfort as well as poor indoor air quality.
Various subcontractors are involved at these junctures including the air barrier contractor, roofing contractor, sealant contractor and others. The connection is generally not detailed and assignment of responsibility is critical to ensure an effective connection as well as one that is airtight and flexible between assemblies.
In order to prevent leakage issues in the transitional spaces between systems of the building as well as premature deterioration of building components and operating efficiency of the building, connectivity and compatibility of the transition interface must be a fundamental design element.
