FAQ

Insulation is one of the most important measures to take when boosting the energy efficiency of a building. No other measure can save as much energy for heating. 

Manufacturing the insulating materials consumes much less energy than the materials ultimately save. The energy used to manufacture insulation materials is marginal compared to the energy saved in a dwelling over a period of 20 to 30 years. As such, the energy consumed in manufacturing insulation does not constitute an argument against energy retrofitting, but it can very well influence the choice of insulating material. According to Klimabonus State aid criteria, environmentally friendly insulation requires little energy to produce.

The Klimabonus programme provides substantial subsidies for the use of environmentally friendly insulation.

When improving building energy efficiency, insulation measures have the highest priority. No other measure can save as much energy for heating.

Several studies demonstrate that the production of insulation materials consumes much less energy than is saved later. Even with 30-centimetre thick insulation materials, such as polystyrene, the production energy required is already amortised after about three years.
