EXTERIOR INSULATION system...
Why insulate the walls
The opaque vertical structures which delimit most buildings bear the greatest responsibility for thermal exchanges between the inside and the outside.
It is estimated that when restructuring, thermally insulating the external walls alone allows achieving energy savings of 20-25% in the case of single-family buildings, and of 30-35% for condos.
In passive buildings and in those with a very low energy consumption (Nearly Zero Energy Buildings) the opaque outside walls are characterised by very low thermal transmittance values, ranging between 0,10 e 0,20 W/mK2.
These values can be obtained through various building methods and by placing the insulating layer:
The advantages of external insulation
Insulating externally produces performance, operational and economic advantages:
When restructuring, insulation from the outside has further advantages:
