The building envelope isequivalent to the skin of a building. In essence,a structure must be envelopedfrom top to bottom to prevent intrusion from nature’s elements into interior spacesand to protect the structural components from weathering and deterioration. Envelopescomplete numerous functions in a building’s life cycle,including
? Preventing water infiltration
? Controlling water vapor transmission
? Controlling heat and air flow,into and out of interior spaces
? Providing a shield against ultraviolet rays and excessive sunlight
? Limiting noise infiltration
? Providing structural integrity for the façade components
? Providing necessary aesthetics
? Preventing of mold formation and growth
