A building envelope assembly is the physical barrier between the interior and exterior of a building, consisting of all the materials and systems that work together to provide protection from outside elements such as air, water, heat, and noise. It includes the roof, walls, windows, doors, insulation, vapor barriers, and weather-stripping.
Building envelope assembly is crucial in building design because it affects the building's energy efficiency, durability, and comfort. A well-designed and constructed envelope assembly can reduce energy consumption by decreasing heating and cooling demands, prevent water infiltration and moisture buildup, increase sound insulation, and contribute to the overall aesthetic of the building. It also plays a vital role in maintaining indoor air quality and preserving the building's structural integrity, preventing damage from pests, and fire.
