The Walls, Windows and Doors.

About Lesson

Exterior Walls:

An exterior wall is a vertical structure that separates the inside and outside of a building, and can be finished or unfinished. Exterior walls can be bearing or non-bearing, and have a slope of at least 60 degrees relative to the horizontal plane. They are often part of a building’s envelope and can serve many purposes, including:

Environmental control: Mediating between indoor and outdoor conditions
Weather resistance: Keeping out the weather
Security and privacy: Providing a barrier
Sound proofing: Reducing noise
Supporting the roof and floors: Providing structural support

Windows:

In building construction, a window is an opening in a wall, door, roof, or vehicle that allows light, air, and sometimes sound to pass through. Windows are usually closed by casements or sashes that contain transparent or translucent material, such as glass, mica, or paper. They can be opened and shut, and may have a latch or similar mechanism to lock them shut or hold them open.

Windows serve many purposes in building construction, including:

Natural ventilation: Windows provide controlled natural ventilation to buildings.
Visual appearance: Windows can contribute to the visual appearance of buildings and can be used for architectural decoration.
Outside views: Windows allow people to see outside.

Doors:

In building construction, a door is a movable barrier that is fixed to a frame in a wall opening, or doorway, to allow people to enter and exit a building or room. Doors can be made of wood, stone, metal, glass, paper, leaves, hides, or a combination of materials. They can swing, fold, slide, or roll to close the opening. Doorframes, located at the top and sides of the doorway, hold the door in place.

Doors serve many purposes, including:

Security: Controlling access to the doorway is a door’s primary purpose.
Connection: Doors connect the internal parts of a building.
Privacy: Doors can provide privacy.
Temperature regulation: Doors can help regulate temperature.
Noise reduction: Doors can help reduce noise.
Controlling people and air: Doors can help control people and air.

Doors are classified as non-structural building components. They and their frames are an integral part of the wall’s overall performance, whether it’s internal or external.
