Have you ever noticed the ornate edge of a building’s roof from above? Do you know the name of the element of this structure? Explore the functions of plasterboard and cornices in architecture in this course.
Why are there ledges?
The components of a building include items such as windows, doors, and chimneys. In addition, they have distinctive architectural features that provide decorative and characteristic functionality. A decorative border called a cornice is just where the wall comes into contact with the roof or ceiling. The interior and exterior of the works are used only. The place where the wall meets the roof is where the moldings can be seen only on the exteriors of buildings. It can be seen when looking up as the horizontal portion of the wall that protrudes just below the roofline. Imagine it as a crown. The beautiful wood or sheet plaster moulding, sometimes made of plaster, thus the word “moulding,” that rings a room directly below the ceiling is known as the cornice in interior design. We’re going to concentrate on a few different exterior cornice types in this session.
History of Cornice
Ancient Greek and Roman architecture is where the concept of a cornice first emerged. The cornice was the crowning feature of the entablature, the horizontal portion of a building’s exterior that sits directly above a row of columns and beneath the roof in classical Greek architecture. Cornices served a fundamentally practical function by deflecting rainwater away from a building’s sides, but they soon evolved into ornamental features as well. Three orders existed in Greek architecture:
- Doric, which has extremely straightforward and geometrical lines.
- Ionic, which have scroll parts and are a little more ornate.
- Corinthian, the most intricate with leaves and other components
What differentiates sheet plaster from drywall?
Unless there is an issue or they move into a studio apartment, the majority of people rarely consider the walls in their homes. However, inner barriers offer seclusion and privacy. Additionally, they can serve as acoustic barriers, insulators, and even provide increased fire protection. Sheet plaster and drywall are the two most common materials used for interior walls. Since the dawn of time, plaster has been used. The traditional ingredients of the oldest plaster are lime, sand, animal hair and water. It is known that frescoes were used to decorate ancient Roman homes. Frescoes are works of art painted on wet plaster using different colours.
Gypsum is the most common type of plaster used for interior walls. Sheet plaster is usually built using the three-layer method. Lath needs to be fastened to the framing first. Lath has traditionally been built of strips of wood, but more recently metal or plasterboard have been used. The lath provides a surface for the sticky plaster to adhere to. The plaster compound needs to be mixed after the lath is installed. The substance typically arrives dry and needs to be combined with water. Although this procedure may seem rather simple, it takes some skill and practise to get the desired consistence. The plaster can then be used to cover the wall. Applying, scuffing, and waiting for the first coat of sheet plaster to cure. The second coat, sometimes known as the brown coat, is applied next, and the final layer is used to complete the wall.
