Why choose marmoroc stone?

Marmoroc

• is a light, thin, and strong stone façade
• can be installed in any season and allows you to build a façade quickly and rationally
• is the best ventilating façade solution in case of additional heat insulation, and is the perfect exterior wall lining material
• made of crushed marble, cement, and pigment. The stone façade surface is slightly rough and coated with a hydrophobic layer
• available in many colours, and different colour combinations can be used to cover the façade
• hot-dip galvanized steel is used in the manufacture of the mounting frame. Frames are perforated at the bottom for their more convenient installation

Marmoroc is practically maintenance-free

The oldest house covered with Marmoroc is over 40 years old; the oldest in Estonia, over 20 years old.

The lifespan of the currently very popular insulation plaster could be up to 25 years if certified synthetic plaster systems are used and the façade is maintained according to the manufacturer’s instructions. This means visual inspection annually and repainting the entire façade every 5 to 7 years.

Erek OÜ has been selling and installing Marmoroc in Estonia for 25 years. As it is a concrete stone, Marmoroc is certainly the longest-lasting façade cladding on the market today. Empirical data confirms that houses insulated in Sweden up to 50 years ago and covered with Marmoroc still do not require any maintenance.

Marmoroc is a ventilating façade solution

Non-ventilating façade solutions, i.e. synthetic plaster, have been recognized as a risky in our climate at the Façade Building Physics seminar. An important difference between these systems is that the non-ventilating façade has both a heat insulation coating and a rain coating in one layer. Therefore, the façade surface cannot dry properly and over time it will crack and a layer of algae will form on the surface.

However, the advantage of a ventilating façade cladding is the fact that a ventilation gap behind the façade cladding ensures the protection of the heat insulation from rain. Water that can penetrate through the façade is also not in contact with the heat insulation. The ventilated coating also dries quickly, as drying takes place both from the front and from the back.

Therefore, a ventilating façade cladding system performs all the functions required from a façade: it protects against the effects of the weather, ensures better air quality in the living space due to “breathability”, and is resistant to mechanical impacts. A big advantage in case of vandalism or graffiti is the possibility for the simple, fast, and cheap partial replacement of stones. In the developed countries around us, the attitude towards synthetic plaster has been very cautious and selective for many years, and it is positive that we are finally moving in that direction as well.

Marmoroc is a ventilating façade cladding system manufactured in Sweden, where light stone façade is laid on a special installation frame without the use of mix or mortar. At the same time, the frame creates necessary ventilation chambers, through which the moisture can easily escape from the building. Thus, the situation is achieved that the building is heat insulated, the appearance is tidy, and the indoor climate has not deteriorated, because all the materials used are “breathable”. The stone is made of crushed marble, cement, and pigments; the installation frame is made of galvanized sheet steel. The choice is from among ten colours.
