The use of thermal insulation materials in modern constructions, apart from being obligatory by building regulations, protects them from the external environment. At the same time however, it responds to one of the most crucial problems of our times, which is the ever increasing consumption of energy for heating or cooling.

External thermal insulation is the perfect energy-saving solution for buildings, either newly built or old, because it deals effectively with the main cause of thermal losses, which are thermal bridges.

Thermal bridges are parts of the of the building’s envelope where thermal resistance of the building components is reduced and thermal losses appear.

Thermal bridges usually arise:

  • in the space between two different building components or between two same components of different thickness
     
  • in external building components’ joints
     
  •  around openings

Technically, thermal bridges cannot be completely avoided. However, the use of expanded or extruded polystyrene, for external insulation, is the ideal solution for problems caused by thermal bridges, because it:

  • Minimizes the development of thermal bridges
  • Prohibits the creation of condensation on beams and pillars 
  • Saves more than 50% energy, with a respective reduction in cooling costs 
  • Improves the static loads in masonry while 
    increasing the building’s inner space 
  • It rids the building of unnecessary loads 
    (double-wall masonry) 
  • It offers unique opportunities for architectural modelling and decoration, in new buildings or in buildings to be enovated, regardless of size and complexity.
