ᐅ Is the construction standard?

Hello everyone,

Today I passed by a construction site and noticed that up to a certain height, sloped polystyrene insulation boards (?) were installed against the calcium silicate brick wall. At the edge, a membrane is attached to the masonry, which is then extended up to the facing brick and the facing brickwork continues on top of it. I have also seen cases where mineral wool was packed in all the way down.

Since we will be starting very soon as well, I am curious if there is really a difference between these methods, or if they are just two alternative options.

Here is a photo of it:

In the construction shown in the photo, a non-absorbent insulation is installed at the lower section. The waterproofing is applied over this insulation to the exterior, allowing water to be drained out through drainage openings.

Above this rigid, non-absorbent insulation, a soft insulation is installed and held in place on the interior masonry by clips attached to wire anchors.

This design of the base area, as shown in the photo, is the one I consider correct, as it complies with the relevant standards.

Best regards

Okay, then I hope that it will be done like this in our case as well... it is not described in the building code / building regulations 😉 but well, there is not much described there anyway...

Ask for a detailed drawing of the base area.

It could look something like this. (sorry for the poor photo)

Many thanks – also for the scan, we will bring it up with him. Would it be considered a defect if he didn’t do it? The building supervisor actually has a good reputation and is very locally based. I just don’t think he will do it if he usually does it differently 😀

I can’t say whether this is a defect. I am very cautious with such statements.
