Hello,

I have a question about roof insulation according to the Energy Saving Ordinance 2009.
In 2013, we built our detached house with 1.5 stories and a 45° roof pitch.
However, no insulating wool was installed on the ceilings in the attic.
Is that permissible? Or is it sufficient if the ceiling of the upper floor is insulated?

Attached is the energy calculation file.

The attic is unheated and separated by a well-insulated staircase - so everything is fine. If you want to convert the attic, you naturally have to change that (not just the insulation).

Why was an additional underlayment installed?

Thank you for the information. Would it provide any additional energy benefits if I were to insulate the attic as well? The attic is only used as a pure storage space.
