Insulation

Good insulation can reduce your home's energy consumption by up to 50%. In Spain, where air conditioning accounts for a large part of summer electricity bills, properly insulating facades and roofs is the most cost-effective long-term investment.

Frequently asked questions

All about insulation
in Spain.

How much does home insulation cost?

Insulating an 80 m² home costs between €3,000 and €10,000 depending on the system (external ETICS, cavity injection or internal insulation). Cavity insulation is the most affordable.

Which insulation is most efficient?

ETICS (external insulation) is the most efficient system as it eliminates all thermal bridges. If external work is not possible, cavity wall injection is the best alternative.

Are insulation subsidies available?

Yes. EU Next Generation programmes fund up to 80% of thermal insulation costs in homes, up to €6,300 per dwelling.
