COATING STONE FRONTS

SLATE FLOORING FACADE

Versatility, durability and sustainability are three of the characteristics of natural stones that make them one of the best coating materials for facades and roofs. between the natural stones used for the cladding is noteworthy slate, metamorphic rock composed primarily from clay and sedimentary rocks, sometimes, of igneous rocks.

Slate is a dense rock, fine-grained, cleavage, extremely hard, with a high content of quartz and mica and a layered structure with a plane parallel to the grain stratification.
The variety of colors and textures make the boards as one of the most used for coating both interior and exterior (faades and roofs), classified, commercially materials as blackboards use type I and type II boards. The first one for the coating of interior and the second for coating facades and roofs. This classification is established depending on the density of the Cubiertas in the case of the boards for cladding facades and roofs, its higher density make them more resistant to delamination and low mica content reduces the problems of adhesion direct to other elements.

There are multiple varieties of slate that can be found on the market, some of them even though they belong to group II are not eligible to have a good performance as cladding material and characteristics covered so that only laboratory tests on the adhesion strength and tension ensure the suitability of the board for exterior cladding.

The main benefits of the board as cladding material are its long life, low maintenance, provide good sound insulation and thermal inertia decreases the oscillation of the temperatures inside the houses and provide good protection summer heat. On the contrary the cladding with slate has the disadvantage of making the slower and more expensive by the increased cost of labor and an increased risk of deterioration associated with building moisture. But the main drawback is that to be a very heavy stone requires very strong structures to avoid stability problems of buildings.

To overcome the drawbacks of natural slates in the cladding were created synthetic slates, recreating artificial material properties and original look of natural slate but turns out to be much lighter. Other advantages of artificial slate against natural slate and favor its use as cladding material are:

The artificial slate is practically unbreakable so frequent breaks of natural slate is avoided in the process of placing on the facade.

Less deterioration over time.

High degree of impermeability and thermal insulation which favors energy saving.
