Insulation and energy efficiency: where to start in your home

Order matters: first cut demand (insulation), then efficient systems (heat pump), then generation (solar). Real savings per measure.

In what order should you upgrade?

First cut demand (insulation and windows), then install efficient systems (heat pump), finally generate (solar PV). Reversing the order means buying oversized machines and panels.

Which insulation gives most per euro?

If your façade has a cavity: blown-in insulation — one day, €18–30/m², immediate comfort both seasons. No cavity, or a façade needing repair? EWI solves both and unlocks the biggest grants. The roof is the other critical point — up to 30 % of losses.

How much is really saved in Andalusia?

A typical home combining insulation + heat pump + solar cuts total energy spend by 60–80 %. With current grants, payback for the whole package drops under 10 years. See insulation and heat pumps.

FAQ

Frequently asked questions

How do I know if my wall has a cavity?

Homes from 1960–1990 almost always do. We confirm it in the visit with a borescope through a 12 mm hole, free of charge.
