Building Envelopes

The building envelope is the fabric of a structure that must work integrally to maintain water and air-tight barriers. The envelope must also “breathe” to prevent uncomfortable living conditions. Whether roofing, facade, windows, plazas, or subsurface waterproofing, our staff understands the importance of how all building materials must act integrally with one another. Mold, condensation, drafts, and water intrusion can easily lead to the premature structural deterioration. Joseph B. Callaghan, Inc. will analyze a facade or existing building envelope for better performance and the thermal efficiency.
