Technology Solutions Case Study: Guidance on Taped Insulating Sheathing Drainage Planes
The energy efficiency-based financial benefits of adding exterior insulation are well accepted by the building industry, and using exterior insulation as the drainage plane is the next logical step. This case study focuses on the field implementation of taped board insulation as the drainage plane in both new and retrofit residential applications, and provides information and recommendations for insulation contractors, general contractors, builders, remodelers, mechanical contractors, and homeowners. The order of work completed during home construction and retrofit improvements is important. Health and safety issues must be addressed first and are more important than durability issues, and durability issues are more important than saving energy. Three significant items are required to make taped insulating sheathing a simple, long term, and durable drainage plane: first, horizontal joints should be limited or eliminated wherever possible; where a horizontal joint exists, use superior materials; and, frequent installation inspection and regular trade training are required to maintain proper installation.
