The question is already stated above; actually, our energy consultant should inform us promptly, but they are currently very busy.
Our construction company wants to order the insulation as soon as possible due to another announced price increase.
Therefore, the question to the group... For the Effizienzhaus 55 (efficiency house 55 standard), which cavity insulation should we use? The 035 (0.035 W/m·K) would be significantly cheaper, but the problem is whether it meets the requirements.
Thanks for your answers.
