So, we are facing a decision between two building contracts. We will receive the final offers with all changes in the coming days.
Building contract #1 uses 17.5cm (7 inches) Poroton T18 blocks, while building contract #2 uses 24cm (9.5 inches) Poroton T18 blocks. External thermal insulation composite system (ETICS) is specified as 20cm (8 inches) for both. Now I’m wondering if 17.5cm (7 inches) could present any disadvantages for us, and if so, which ones? Based on gut feeling and the included services, we actually prefer building contract #1.
Thank you very much in advance for your help.
Best regards

toxicmolotof3 Aug 2016 08:36I wouldn't have recommended either green or yellow for the car, as the resale value is generally lower compared to, for example, a silver-colored vehicle. Of course, if you plan to keep the car until the very end, the color doesn’t really matter, unless the silver vehicle has better overall features.
By the way, the thermal conductivity is actually quite high rather than low. You’ve probably mixed that up.
Next arguments in favor of sand-lime bricks: wall-mounted cabinets and heat storage capacity.

But high, for me, means a value where I could use the brick without an external thermal insulation composite system (ETICS). In other words, filled Poroton.

They used 17.5cm (7 inches) T18 blocks with an ETICS from another regional supplier. Sure, sand-lime brick has advantages here.
b) Thermal storage capacity, but isn’t that negligible because of the ETICS!?
Conclusion: So, as an advantage, I see the load-bearing capacity due to the high bulk density and the better sound insulation. The load-bearing capacity is the only thing that makes me think. Especially since we are building a single-family home and not a terraced house, semi-detached house, or a multi-story residential building.

toxicmolotof3 Aug 2016 09:24Thermal conductivity is not the same as thermal storage capacity.
High thermal conductivity = poor insulation performance (in this case, the external thermal insulation composite system (ETICS) is the more important component).
Thermal storage capacity causes a phase shift. Here, calcium silicate brick can absorb about 50% more "heat." Temperature fluctuations become slower.
But I’ll hold back now—I have no expertise and am just an amateur anyway.

@toxicmolotow
Yes, you better hold back. You’re just repeating what I already politely asked and pointed out to you. I tried to communicate with you. It seems pointless. And obviously, you didn’t even look at the pictures... Otherwise, you would have seen from the values shown there that the phase shift is not relevant.
Goodbye

PS: Just build with Poroton and leave the rest of the forum alone with your unshakeable knowledge.
