Wall Thermal & Sound Insulation

The external appearance of a building creates its image in public space, reveals its identity and portrays the creative efforts both of its designer as well as its inhabitants.  The facade finishes, the textures and colours combined on its elevation shape a structure's character.    

The life span and performance of the facade may be greatly enhanced with the application of an appropriate External Thermal Insulation Composite System, depending on the desired external appearance and character of the building.  Further, the choice of the most efficient thermal insulation material of adequate thickness assures, apart from sustainable thermal comfort, the sound insulation and fire protection of the building envelope--creating a Facade Energy Shield.

Sustainable thermal comfort, sound insulation and preventive fire protection are assured with:

  • Selection of the appropriate external thermal insulation composite system
  • Selection of the appropriate thermal insulation material
  • Adequate thickness of the thermal insulation material
  • Application of the render or the cladding elements according to the manufacturer's instructions
  • Attentive construction of the details, by experienced applicators

 The application of an efficient External Thermal Insulation Composite System ensures:

  • Sustainable thermal comfort,
  • Sound insulation,
  • Fire protection,
  • Longevity of the insulation application,
  • Renewed aesthetic appearance.


When selecting the right insulation material, and to ensure the durability and stable performance of the application in the passage of time, special emphasis should be placed on the energy-efficiency of the external thermal insulation as a complete system, on its vapour diffusion characteristics in extreme temperatures, as well as on the system's resistance to moisture.  The External Thermal Insulation Composite System should be selected taking into account the location of the building in terms of area climate and orientation, its use and height, the fire protection requirements for the particular building typology.  The selection of the right insulation material may simultaneously satisfy thermal and sound insulation requirements and provide or enhance the structure's fire resistance.


The thickness of the insulation depends on the current regulations for the design of energy-efficient structures, laws on the sound insulation and acoustic performance of building uses and the fire resistance requirements for particular building typologies.  Therefore, the thickness of the insulation material may be:

- either the minimum thickness required according to standing legislation, depending on the building's location and its intended use,

-or, the optimum thickness for the improvement of the structure's energy performance.
