ABAA is constantly receiving requests for more information about detailing. ABAA recently issued an FAQ that states:

“The general contractor and sub‐contractors are responsible for providing project specific shop drawings that include manufacturer input.  All details relevant to the project should be provided including, but not limited to, intersections with other envelope assemblies, details showing how gaps in the construction will be bridged, inside and
outside corner transitions, how claddings are secured with the air‐tightness maintained, and how miscellaneous penetrations such as conduits, pipes, electric boxes and similar
items are sealed.  The shop drawings need to be reviewed and coordinated with related trades and reflect the sequencing of construction.”

“Manufacturer standard details can be used as shop drawings when they mimic the jobsite conditions. However, when the manufacturer standard details do not mimic the
jobsite conditions, they are to be modified by the contractor with input by the manufacturer, to replicate project‐specific conditions.”

This presentation shows how designers, consultants and contractors can work with specialists at air barrier manufacturing companies to obtain shop drawings that optimize the use of fluid-applied detailing products to replace peel&stick and assure a durable air-tight and waterproof building envelope.

1. Explain how architectural drawings are sometimes lacking in structure amenable to waterproofing and air-barrier detailing.
2.  Demonstrate how simple modifications can greatly enhance constructability and detailing to prevent water intrusion and air leakage.
3. Show how to draw air / water barrier details to facilitate use of fluid-applied products rather than self-adhered membranes and building wrap.
4. Explain how to work with manufacturers to optimize preparation of details for implementation by contractors.
