Exterior Wall Insulation Subsidies in Europe

Exterior wall insulation (ITE in France, WDVS in Germany, cappotto termico in Italy) is the most expensive but most effective thermal renovation. Costs run 100-200 EUR/m2 for a typical facade, but subsidies are proportionally generous. France provides up to 75 EUR/m2 via MaPrimeRenov for very modest incomes. Germany's BEG EM covers 15-20%. Italy's Ecobonus offers a 65% tax credit. The high cost makes subsidies essential for financial viability.
