Abstract
Lapses in building envelope construction are no longer acceptable. Expansion joint closure systems are now under the same scrutiny as the rest of envelope. Due to the dynamic nature of their purpose, they may not always be able to attain the exact same results; however, it is possible to approach the overall design criteria with proper and timely communication, planning, detailing, and installation. Expansion joint closure systems are not only barriers against air, weather, temperature, noise, and fire but also must provide this security while constantly moving with the building. They potentially make more abutment material transitions and bridge between different substrates with more trades doing the installation than any other product on the job. This is where a full building flow diagram and 3-D details convey information to all. As always, the system is only as good as its weakest link.
