Do you know what drywall is?

The way in which the construction of new homes, businesses, factories and all types of buildings is developed is changing. New materials, technologies, machines and construction methods are already being put into practice in Brazil and worldwide.

Aiming to build more efficiently, quickly, and safely, these new systems appear to make buildings and, therefore, our houses, more functional, dynamic, allowing a very contemporary manipulation of space.

The drywall system is a clear example of this. The word, in English, means “drywall”, meaning that it doesn’t need a wet component to be built. While the conventional masonry wall is composed of a set: bricks or blocks, ceramic or concrete, joined by a mortar, the drywall system is carried out by the assembly of prefabricated elements. This is dry construction.

How is drywall constructed?

Commonly called plaster wall, it is composed of a structure of metallic profiles that, after position in the work, receives plaster plates on both sides of the structure.

These metal uprights are galvanized steel profiles, placed in such a way as to generate a structural framework for fixing the plates. They have arranged vertically approximately one meter apart.

The interior of the walls is filled with thermo-acoustic insulation, which can be wool or fiberglass, for example.

In addition, there are three types of drywall boards, which differ because of their internal color. White is the most basic and therefore the most common; green is water-resistant and contains water repellents in its formula, and the rose is more resistant to fire as it contains fiberglass.

Types of plasterboard: green, pink and white.

Where can I use drywall?

The variety of boards allows the system to be used in different environments. For dry spaces, such as living rooms and dormitories, the whiteboard is used; in wet areas, such as bathrooms and kitchens, the pink plate is applied.
Drywall supports the application of wall coverings, such as tiles and ceramics, which are often used in humid environments. The application is done in the same way as on a masonry wall, with the advantage that the drywall is perfectly flat.

In addition, objects such as shelves, paintings and benches can also be attached to the walls. For this, it is important that these items are provided for in the project, as it is necessary to reinforce the internal metallic structure of the wall at the fixing points.

Far beyond walls

There are also drywall ceiling systems. These follow the same logic as the walls and are built based on a metallic structure where plasterboards are fixed.

This type of modular feature features easy assembly and flexibility. It is widely used in offices and businesses.

Spatial flexibility 

Drywall walls, as they are not the elements responsible for the structure of buildings, are dynamic mechanisms for the creation of space division. Added to this the easy assembly, the system becomes fast and efficient.

This spatial flexibility is very welcome in apartments, for example. Increasingly used, the drywall system allows, for example, that the same floor plan of an apartment can be occupied in different ways, allowing that, in equal areas, a loft or an apartment with 1, 2 or 3 bedrooms can be created.

The Cotoxó 926 building is a clear example of this. From the construction of its structure on the perimeter of the building, the plan of the apartments is free for the residents to adapt it in the most favorable and pleasant way.

This versatility supports the contemporary, dynamic and changing way of life. From growing families to create larger spaces for collective living, all of this can be quickly accomplished through the drywall system.

Advantages of the drywall system

  • As it is modular and dry, the drywall system has many facilities. The construction time is up to five times less than conventional construction, in addition to generating much less rubble. This is one of the main reasons why the system is being used more and more in renovations, for example, where efficiency and cleanliness are key factors.
  • After the work is finished, it is much easier to access the interior of a drywall wall than a masonry one. As the plates can be opened and closed, it facilitates changes in installation or placement of reinforcements to fix new objects.
  • Drywall walls and ceilings are capable of absorbing internal ambient noises, in addition to isolating outside sounds, providing spaces with a high level of acoustic comfort.
  • Through this system, it is possible to reach interior spaces that are larger than those made with masonry, given the smaller thickness of drywall walls, which can be quite thin without losing their quality.
  • As it is a lightweight system, it makes the building structure more economical.
  • Drywall walls can be painted and coated, decorated according to your style.
  • As it is not structural, the system allows for the flexibility of environments, facilitating changes in its interior. With drywall, it is simpler to join or separate two environments, for example.
  • It is a more sustainable construction methodology, it generates less waste, the material can be reused even after it is demolished, it requires less labor. All this makes the construction more rational, efficient, and contemporary.
