Improved Use of Space

One should assume that a room, if it is planked on the outer wall with a 7cm interior insulation panel, becomes smaller. And purely mathematically, that's the way it is. But subjectively, you even gain space. How can that be?

As a rule, the space is avoided in front of an uninsulated outer wall due to the outgoing cold. Thanks to the naturbo interior insulation panel, the surface temperature of the outer wall is now increased by a total of 3 – 5 °C. The room immediately in front of it is now perceived as pleasant. In this way, it is used much better – and the use of space is thus improved.
