Advantages of gypsum on the ceiling


The application of gypsum on the ceiling brings aesthetic and practical benefits. Here are some of the main advantages:

Elegant finish


Gypsum allows for sophisticated finishes with details that enhance the design of the project and highlight the lighting.

Built-in lighting


Being moldable, gypsum allows for the integration of different types of lighting fixtures into the project (such as spots, LED profiles, pendants, and wall sconces) in a clean and functional way.

Concealing Structures


ducts, beams, electrical cables, and air conditioning systems can be disguised with the strategic use of gypsum, resulting in a uniform and organized ceiling.

Sound and thermal insulation


When combined with glass wool or other insulating materials, the gypsum ceiling contributes to the thermal and sound comfort of the projects.

Types of gypsum on the ceiling


There are different ways to apply gypsum on the ceiling, and each provides a distinct visual result.

Gypsum board ceiling (drywall)


The most widely used today, drywall ceilings are lightweight, quick to install, and provide a uniform surface, ideal for minimalist projects. It is also the best choice for embedding fixtures, tracks, and air conditioning systems with precision.

Open Cove


Indicated for those seeking an indirect light effect. The open cove has a gap between the wall and the gypsum where LED strips or embedded lighting can be installed. The result is a diffused and cozy lighting.

Closed Cove


The closed cove, on the other hand, is continuous and without visible openings, which can be smooth or with decorative moldings. It offers a more classic and elegant finish, ideal for living rooms and social areas.

Gypsum moldings


For those who prefer pointed interventions, decorative gypsum moldings serve as a decoration for flat ceilings. They are widely used in traditional projects and can be combined with rosettes and boiseries for a refined look.

Where to use gypsum on the ceiling


Gypsum can be applied in basically all the projects of the house, respecting the particularities of each space.

Living and dining rooms


These are the most common places for coves and gypsum designs. In these projects, gypsum can create drop ceilings that demarcate areas, such as over the dining table or sofa.

Kitchens and bathrooms


In these spaces, it's best to use humidity-resistant gypsum board (RU). The material also allows for functional lighting installation and conceals exhaust ducts.
