Just like a common wall, this type of fence includes vertical support beams and pillars, which are placed in short, modular spans. These elements are metallic, made of galvanized steel. It is also necessary to place wooden structures, which function both as a guide and as horizontal support.
Furthermore, the wall drywall It usually has mineral wool filling for thermal-acoustic insulation. Finally, to make the covering, boards with natural plaster interior and additives are used, covered with two sheets of cardboard.
The sheets are fixed to the metal structure using screws. After this step is completed, the seams are reinforced with tape and the finishing is done by applying putty. As a result, we have a resistant wall, but also thin and light.
What are the benefits of drywall?

-
It’s sustainable
Drywall manufacturing requires little energy. Furthermore, its installation generates less than 5% of waste, compared to 25% of common masonry. Furthermore, all of its waste is recyclable. Therefore, the material is better for the environment.
-
Makes maintenance easier
In order to carry out repairs to the electrical or hydraulic network, simply cut the drywall, make the repair and fit the cut piece back. No crashing!

-
Allows good insulation
According to the Brazilian Drywall Association, the thinnest wall using this technology already offers acoustic insulation equivalent to that of a common wall that is approximately twice as thick.
-
Ensures accuracy

Both the drywall and plaster are made with the same raw material, gypsum. However, while the first serves to compose walls, partitions and ceilings, the second only creates ceilings.
Ordinary plaster is used in the form of slabs. They are fitted together and then suspended by wire. The seams receive plaster and sisal putty and, as a finish, a layer of plaster putty is applied.
Despite being the most popular system in Brazil, it dries slower, makes installation more messy and is more susceptible to cracks than the lining. drywall.
