Hello, my project will start this summer and I need to choose a masonry block now. The options are Poroton T9 unfilled and T8 filled with mineral wool (additional cost 2500 €). My question is (I have done some research already): Are the unfilled blocks really much more prone to cracking than the filled ones? I have looked at them, and the webs are definitely much thicker. The mineral wool is packed very tightly, so I hope it will only shrink a little over the years.
Thank you for your help.
Best regards

How close to the street do you live for it to be noticeable to you?I live about 300m (980 feet) away from a lightly trafficked local main road. But that's not the problem...My own heat pump (outdoor unit), a new development area full of children, air traffic at 4000m (13,100 feet) altitude, and so on... there are countless sources of noise in rural areas other than cars.
