The facade renovation is carried out to increase the energy efficiency of the building, i. e., to reduce thermal conductivity from the inside of the building to the outside, as well as to prevent the erosion of external walls and protect them from adverse environmental impacts. The warm and safe housing contributes to a healthier and more comfortable living environment and saves up to 50% on heating costs.
Facade modernisation / renovation of the old buildings is a more complex process due to the accumulation of moisture and salts in the masonry, but it can be implemented smoothly and successfully in accordance with the design and technical requirements and by selection of suitable insulation systems.
In order to achieve a great result and live in a warm and cosy home, attention should be paid to the proper insulation of the building facade. Two methods of building facade insulation are possible: ventilated and plastered (“wet“).
The peculiarity of the construction of the ventilated facade is that a gap is left between the wall, facade insulation material and the decoration layer, where the air circulates freely and thus prevents moisture from forming and being absorbed into the insulation material. The galvanised steel or aluminium profile frames are used in ventilated facade systems. The walls breath – the air moving in the gap evaporates moisture faster after rain or under other environmental conditions that can cause moisture.
The plastered facade is also often called “wet“. This is a method of facade insulation where the insulation material is attached to the house wall without leaving an air gap. The properties of the plastered facade are no worse than the properties of ventilated facade. The plastered facades are often selected due to a wide range of colours, a variety of types of plaster and quick and easy installation.
It is mistakenly assumed that the walls of the plastered facade do not breathe. The properly selected quality insulation materials and decoration will allow the house walls to breathe.
