A cornice is a decorative element that is typically installed at the intersection of a room’s walls and ceiling. It is a type of molding that is used to enhance the aesthetic appeal of a room, and it can be made from a variety of materials such as plaster, wood, and gyprock.
What is Cornice?
In internal gyprock plastering, cornices are used to add architectural detail and character to a room. They can be used to create a sense of height, to conceal the gap between the walls and ceiling, and to add visual interest.
Gyprock types are typically made by cutting and shaping pieces of gyprock, and then attaching them to the walls and ceiling using adhesive and fasteners. They can be painted or papered to match the walls, or they can be left unpainted for a more textured look.
Gyprock types are popular in the internal plastering industry due to their durability, ease of installation, and cost-effectiveness. They can be used in both new construction and renovation projects, and they can be customized to match a wide range of architectural styles. They are also a good alternative to traditional plaster types as they are less fragile and easier to install than plaster types.
