Insulation
General
INSULATION is the hidden QUALITY in the building.
It is the only expenditure in the construction of a building that will be amortized because of the energy saving, by providing warmth in the winter and chill in the summer. In a few words, it offers us “QUALITY of LIFE”.
We do not have the possibility of intervening in the insulation of a building afterwards and for this reason we should be careful and ask the advice of experts on insulation products beforehand. Insulation is not only needed under concrete floors and cavity walls but also in all the exterior elements of a building, which if we ignore, they will cause unpleasant surprises in a short period of time.
The choice of insulating materials is considered particularly critical. The most important factor in the decision process of the most suitable material is the thermal conductivity coefficient (widely known as “λ” lambda factor), that characterizes every material. The smaller the lambda value of a material, the better its thermal insulating properties are.

Insulation leads to money savings in the future.
The cost of the insulating materials in the total cost of a building is statistically 2%. It is one of the most important decisions that one must make when he/she builds and so it is crucial that he is always well informed. In the building phase, the insulation is more economical that when the house is completed. At that stage it is expensive and difficult.
Expanded Polystyrene as an insulating material has the best price-performance ratio. It is truly what we call value for money.
The new European Directive 2002/91 EC Energy Performance Directive (EPD) issued by the European Parliament on 16.12.2002 makes obligatory the existence of an Energy Certification of all Buildings, in every transaction procedure (sale, lease) in old and new buildings. Each building therefore, will have to acquire its own Energy Performance Certificate.
Consequently, soon that the energy identity of buildings will be obligatory and controllable, it will be more difficult and expensive for the non-insulated building to be insulated.
