What is the Building Envelope?

To understand the importance of a building envelope consultant, you must first understand what it is we are looking at during your consultation. Technically, a building envelope is the physical separators between the conditioned and unconditioned environment of a building including the resistance to air, water, heat, light, and noise transfer. Simply put, the building envelope consists of everything that makes up the shell of the building. It is the building’s wall system, doors, windows, roofs, slabs, foundations, basements, balconies, and storefronts.
