Niko, hello from Heraklion, Crete! I just got to read your thread and I also checked your website, quite impressive!
Just a quick question regarding your wall's structure... I noticed that you have 3 layers of AlfaBlock installed, inner layer for the CR, inner layer for the LR and an additional middle layer. Is there a specific reason to use a 3-leaf system instead of 2-leaf (Mass - Air - Mass) considering that you will get a better TL for high frequencies but worse for low with additional expenses? And the way buildings are constructed in Greece, you need as much isolation for low frequencies as possible...
Thank you in advance for your time!
John
