ᐅ Is it acceptable to fasten downpipes using insulation anchors?

Hello,
our contractor installed the downpipes with a distance of 10cm (4 inches) from the outer edge (16cm (6 inches) external wall insulation system) using 95mm (3.7 inches) insulation anchors (5 downpipe brackets). These are fixed exclusively in the external insulation and look exactly like the insulation anchors I bought at the hardware store for my mailbox.
The construction supervisor noted this as a defect, stating it does not comply with recognized technical standards.
The contractor, however, insists this is not the case. The insulation anchors prevent thermal bridges and do not damage the external insulation despite the lack of movement allowance as would be the case if the brackets were fixed directly into the wall. He also pointed out that this solution is offered by some companies for this purpose.
Does anyone have experience with this? Is this really a defect or could it be advantageous? I am concerned that the downpipes might eventually break together with the corner of the insulation system in strong winds, since the distance to the outer edge at 10cm (4 inches) seems quite small.
I would appreciate any helpful advice.
Best regards

The construction supervision expert noted it as a defect; it does not meet the recognized technical standards. Did they also explain how it should be done correctly?
I believe our setup is only anchored in the insulation as well. But there shouldn’t be any significant loads there, right? Wind load? The weight is primarily supported by the riser pipe. In any case, I’m not concerned about it; our expert did not raise any issues.

Hello Bieber0815,
In our case, the recommendation was to use mounting blocks.
I don’t have any explanation about the problem with the insulation anchors, just that they do not comply with the recognized rules of technology.
Personally, I also feel a bit uneasy. 95mm (3.7 inches) insulation anchors are available at hardware stores, but their use is only intended for signs, lamps, mailboxes, etc. We fixed our mailbox with 4 of these anchors, while the downspouts have 5.
For me, it is not primarily important whether this complies with the recognized rules of technology, but rather whether it will last in the long term. My concerns are as follows:
1. We live on a hill and are fully exposed to wind and storms
2. Our insulation is modified EPS (expanded polystyrene, thermal conductivity WLG032, 16cm (6.3 inches)) and is noticeably softer than regular EPS
3. The anchors are only a few centimeters from the edge. The corners do not have much stability. I would be less concerned if the anchors were further from the edge.
At the moment, I’m facing the problem that I have not yet formed a clear opinion. Although there are online offers for this solution to fix pipe clamps, whenever I try to buy the 95mm (3.7 inches) anchors somewhere, the seller says they are not suitable for this purpose.
