The primary purpose of the building envelope is to separate the interior from the exterior environment. This separation is critical as it protects the interior spaces from external elements such as weather, temperature fluctuations, and moisture. The building envelope consists of various components, such as walls, windows, roofs, and foundations, which work together to create a barrier that enhances energy efficiency, ensures comfort, and maintains the integrity of the building's internal environment.

By effectively managing the flow of air, heat, and moisture, the building envelope plays a vital role in maintaining a controlled indoor atmosphere, which is essential for occupant comfort and safety. Additionally, a well-designed envelope contributes to the overall durability and sustainability of the structure, making it a crucial aspect of building design and construction.
