Suitable stones for the façade

The stone of the main façade should has the necessary resistance to sunlight, cold, heat, humidity, air pollution and other damageable factors. Basically, facade builders and designers use travertine, sand stone, granite and crystal stone in designing the facade of the building. Each of these stones has their special features that we will discuss in details below.

Travertine stone

Compared to other facade stones, travertine has more features. Due to its special structure, travertine has a good adhesion with mortar and separate it from the facade is so difficult. And, it is lighter than other facade stones and it has a high variety of colors. One of the disadvantages of this stone is that it is not a good choice for cold and frosty areas due to its porous structure. The price of travertine stone depends on the type of its color and quarry and basically white ones such as pars travertine are more expensive than the others.

 Granite stone

The main characteristic of granite stone is its high resistance. Due to its high density and very low water absorption, granite stone doesn’t have a good adhesion with mortar and for this reason, if it doesn’t install well, it may separate from the facade. Granite stone is used with polished surface in modern facades. One of the characteristics of granite stone in the facade is its high-pressure resistance and the fact that granite doesn’t absorb air pollution. Among the disadvantages of granite stone facade is its high weight and lack of good adhesion with mortar. The price of white granite stones is cheaper than black, red and green ones.

Crystal stone

Crystal stone has been used in building facades for a long time, even before using granite stones. Nowadays, crystal stone has opened its place in the facade of luxury buildings with new stone processing such as Bookmatch and Fourmatch. Among the characteristics of this stone, we can mention its good adhesion with mortar, low water absorption and a high pressure resistance. White and silver crystal stones are more expensive than others.

Sand stone

Sandstone is formed of various minerals such as silica, iron oxide, calcium carbonate and dolomite. These stones have high resistance and high water absorption. And for this reason, they do not have a good adhesion with mortar. Sandstones in Iran don’t have a variety of colors and they are often seen in yellow, gray and brown colors. This stone is suitable for modern design and it is often use with white stone, brick and wood. The price of sandstone is cheaper than travertine, granite and crystal stones.


A suitable stone for the façade of the buildings should be selected based on the geographical locations. In cold areas where there is a possibility of snow and frost, stones that have less porosity are recommended to use. In addition, in areas where sandstorms occur constantly, the life of the façades become shorter. For this reason, by considering the geographical conditions and climate changes, you can choose and buy a suitable stone.

In general, the stone used for facade should has the following features:

  • It must be free of cracks
  • It must have good bending strength
  • It must be resistant to climate changes
  • It shouldn’t be discolored by sunlight
  • It should be resistant to acid rain
