The Importance of Home Insulation
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 appartments.
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 to 0,20 W/mK2.
These values can be obtained through various building methods and by placing the insulating layer:
- inside the cavity
- on the inner side of the walls
- on the outer side of the walls
