Multipor - need information about suitable anchors for rods

Hello everyone,

I hope I can post my "small" problem here.

We have just moved into a renovated old building. Now we face the problem of wanting to attach rods for curtains to the exterior living room walls. We assumed that ordinary drywall was used. Unfortunately, it turned out that this is not the case and that it is Multipor.

But which anchors are suitable to attach such a rod, on which a rather heavy curtain (thick fabric, over 3m long) will hang—and also be moved.

Has anyone perhaps already gained experience with this material?

I would appreciate any help.

Best regards

Simply ask the question to the all-knowing data sphere! Or look into the corresponding product datasheet of the [Herrsteller].

I was more concerned with empirical values - especially regarding the rather heavy moving load called [Vorhang].

I also found the product data sheet - hence the two variants.

I have now used this one and don’t really find the attached angle fixed:
