ABOUT PLADUR

Currently the Pladur is one of the most used materials in construction as in decoration, due to its good value for money and results at the end of the product. The Pladur is composed of plates signed by two sheets of cardboard (cellulose) recyclable in a central core of plaster that is installed with a screw on a galvanized steel structure that is hidden and through which pass various electrical installations, plumbing, insulation etc.

The plasterboard plates are manufactured in a standardized width 1.20 meters and different lengths of 2, 2.5, 2.6, 2.7, 2.8 and 3 meters. Manufacturers can change the length of the plate to the dimensions of the customer for large enough orders. They are marketed in different thicknesses (10, 12.5, 15 and 18 mm), although for large thicknesses it is usual to superimpose several small thickness plates, placed "a matte together".

Gypsum boards have a fireproof core encapsulated in thick paper, usually recycled paper, with a natural finish on the front and a hard paper on the back, which allows you to maneuver and cut easily, using a knife or a razor, facilitating your installation and immediate application of any type of coating or finishing (paint, paste, tile).

Joints (joints between gypsum board plates) treated correctly during the installation process prevent cracking caused by movement of the frames. In addition to plasterboard plates for normal use, there are plates modified for special uses.

FIRE RESISTANCE

Gypsum board is not flammable, that is, it does not catch fire even when exposed to direct fire. It is made of hydrated calcium sulfate (CaSO4 + H2O) and other compounds. When exposed to fire, calcium sulfate loses water molecules by evaporation, slowing the spread of fire for several minutes. When dried or dehydrated, the calcium sulphate disintegrates (cracks) and the plate crumbles, finally allowing the passage of fire to the other side of the septum. It needs to be installed correctly to serve as a barrier against fire because any perforation or small space will allow the passage of the fire even when the plate has not disintegrated. A thicker plate withstands the onslaught of fire longer than another of the same type but thinner. Two plates installed one on the other also offer greater resistance to the fire, in these cases it is recommended that the joints are alternated to offer greater resistance.

ACOUSTIC ISOLATION

Gypsum boards have a very small mass, so by themselves they do not provide great sound insulation. This isolation is usually obtained by placing an absorbent material placed inside the chamber of the partition, or between the backing plate and the support element. The sound propagates through solid materials such as metal structures that support the plates or through the gaps that remain on the panels. Therefore it is important that the anti-sound treatment be a joint project of walls, structures and ceilings to have a greater effectiveness.

THERMAL ISOLATION

Gypsum boards alone are not good temperature insulators. Due to its thin thickness, heat or cold easily penetrates the plasterboard from one side to the other resulting in uncomfortable temperatures inside the built space. To obtain a good thermal insulation, it is necessary to cover the inside of the walls or roofs with thermal insulation of fiberglass, solid foam plates or other materials.

RESISTANCE TO HUMIDITY

There are gypsum boards resistant to moisture, which are used in damp rooms such as bathrooms, cleaning rooms, kitchens, etc. Moisture resistant gypsum boards are made with treated paper that delays water absorption and fungal growth. In addition the core of the plate contains special additives so that they do not stain or disintegrate. The plates are designed to withstand occasional splashing of water but are not recommended to be exposed to rain or in direct or constant contact with water or steam such as showers, showers or saunas. It can be installed in bathrooms and kitchens of the home without any problem while it has an anti-mildew layer. For the decoration you can stick tile to the same wall but it must be done with a special adhesive for that type of system as mortars-specific for PYL. The plates can have barite coatings or sheets of lead that are bolted to the partition to be used in radiological rooms of hospitals and clinics, to serve as a barrier against ionizing radiation. They can also be covered with fiberglass sheets that are completely washable, for industrial kitchens or food factories. The resistance of a plaster wall is strong because it has three metal poles installed on the back. Its design allows hanging pictures, kitchen furniture. shelves, screens, etc., using the appropriate taquetes. The wall is easier to repair if damaged.
