If you had a building curtain wall leak, would you assume it’s rain water? Maybe so. But what if there was no recent rain, AND if it was really cold recently? Then it might be condensation. If you wanted to find out the source, where would you look? In this case study, you would look at your curtain wall spandrels – constructed of shadow box design. Here you would find ingredients that were ripe for condensation. After finding this problem, WJE sought to figure out a fix. Follow along with how we found the coldness lurking in the shadows – and brought it out into the warming light.
- How are shadow box spandrels meant to be constructed?
- What can happen if there are construction deficiencies?
- How would you diagnose the problem and look for solutions?
- What are pros and cons of the possible solutions?
