Because the basement is unheated, the cold is drawn down to the first floor and this leads to high heating costs, which you can avoid with optimum basement ceiling insulation.

Of course, the requirements of the Energy Saving Ordinance must be observed, whereby you can rely on Swiss Renovation GmbH .

There are various insulation systems with different insulation materials that are tailored to the respective requirements. There are basement ceilings, for example, that are not suitable for gluing and therefore insulation boards that are dowelled or screwed down are recommended.
