External Wall Insulation

External Wall Insulation ETICS

This solution is preferred in buildings of continuous use (residences, hospitals etc), that a stable temperature is desired and the residents are interested in the maintenance of heat after the interruption of heating, rather than the direct attribution of the heating system.

In the case of external heat insulation, we should use a material that collaborates well with the coat such as Expanded Polystyrene with graphite NEOCOAT THP EPS 80 and white Expanded Polystyrene ISOPOR THP EPS 100 or the new hybrid board made of Neopor and Peripor with the brand name ipor THP EPS 100 in suitable thickness according to the regulation of Energy Efficiency of Buildings.

Exterior heat insulation is applied as a combination of insulating material that covers the entire exterior surface of the building without gaps and coat that is applied on the insulating layer. It is a system of various materials and elements that collaborate to one another and are named Externally Insulation Complex Systems (ETICS).

Expanded Polystyrene (EPS) with graphite or without should be suitable for use in external heat insulation and certified for this application. The plates are essentially in small dimensions (1,0 X 0,6m), require special process of maturity and very strict dimensional tolerances. The insulating layer replaces the first layer of traditional coat, which is also the layer of flatness of the surface, known as “rough”.

The coats of external heat insulation are special; resin coats armed with mesh in the whole surface and are applied in small thicknesses. Usually 2 layers are required that overall do not exceed 8mm. The second layer of coat can be colored white and be dyed after, can have various styles in various granulometries or be smooth.



  • It exploits the thermal capacity of wall.
  • It maintains for enough time, that depends on the thermal capacity of the walls, the temperature of space after stopping the operation of thermal bodies
  • It minimizes the probability of shaping thermal bridges that increase the losses of heat at even 25% if are included in the study of heat insulation (now study of energy efficiency according to the regulation of Energy Efficiency of Buildings.
  • It protects the wall from the changes of exterior temperature
  • It minimizes the danger of shaping of humidity.
  • It prevents the damage from humidity and frost in piping of water supply.
  • It facilitates the creation of extreme architectural elements in the building, because these are created with the insulating material


  • The initial heating of the space takes more time.
  • It includes the danger of cracks, if the application is not made from a specialized crew according to the directives of each company which the system is applied
  • Large initial cost of investment.
