ᐅ Concrete blocks behind external thermal insulation composite systems (ETICS), block type or joint masonry, costs

Hello,

I agree completely. You tell the general contractor where the path goes, and you should insist on that.

I would also have the load-bearing interior walls made with adhesive bricks. For the non-load-bearing ones (usually 11.5cm (4.5 inches) thick), you can use other materials. These are typically built only after the concrete slab is poured or after formwork removal.

Best regards

Additional note on hanging pictures.

Use steel nails or alternatively anchors.

Thanks for the tip, I’ve also heard about using steel nails. Somehow, the picture hooks will get attached to the wall one way or another. We valued the sound insulation of the interior walls highly (hopefully with three children), which is also why we decided against aerated concrete. Using anchors just for a few pictures seems a bit excessive to me, but with smaller pictures the nail should only need to grip the plaster anyway, so that should be sufficient...

I believe you are completely mistaken about that. The general contractor must follow what you want. Where would we end up otherwise.........?

That’s true. I have specified a lot myself, including improved roof insulation, since the original simple scope of work only mentioned cavity insulation between rafters. But especially when it comes to masonry, I have to consider what is recommended to me in relation to insulation and building services. Whether I then accept it or not is my decision. For example, I was strongly advised against using fully filled bricks (which I originally thought about). The recommendation was the Liapor Super K Plus, a 30cm (12 inch) stone combined with 14cm (5.5 inch) external thermal insulation composite system (ETICS), which results in an acceptable wall performance and completely avoids thermal bridges, despite all the disadvantages or criticisms of ETICS.

Of course, I set the direction, that’s why I’m involved, but if choosing aerated concrete blocks for example makes the project €5,000 more expensive, that doesn’t help me at all!

There are also different options for ETICS. The higher the thermal insulation proportion of the load-bearing structure, the more diffusion-open the additional insulation must be! This way, you will not have any issues with ETICS.

Hello Behaim, 🙂

We are also thinking about building with insulated brick blocks. Could you please explain the exact reason why you were advised against using these blocks?

Thank you and best regards
