Moisture Management
The building enclosure manages everything that might get into and out of a building: water, wind, light, sound, air, pests, and people. Assemblies are the foundations, above-grade walls, and roofs that make up the enclosure, and how they’re put together makes all the difference to how well the building performs—and for how long.
Here you’ll learn the importance of continuity at assembly transitions, and how to help ensure that the whole team—from architect to structural and mechanical engineers to construction managers and subcontractors—is educated about moisture risks and is accountable for quality work.
