Building Envelope Transitions

Waterproofing/Rainscreen Special Section

Abstract: When a building leaks, the design, workmanship and material of the building envelope are all suspect. The exterior walls, roofing, windows, doors, balcony decks and below-grade waterproofing are all potential culprits. Oftentimes, however, a leak cannot be attributed to just one building envelope component. The way in which the building envelope systems come together is critical to the overall waterproofing performance. As such, the building envelope integrations, from straightforward to complex, must be addressed efficiently and effectively.
