ᐅ Are Fischer wall plugs recommended for use with Poroton bricks?

Hello everyone,

Our construction phase is slowly coming to an end, and of course, we are already planning the next steps. From time to time, the topic of drilling comes up, especially when I think about our sectional door.

Since these Poroton bricks have chambers (on our outside filled with mineral wool), I am wondering if I need or should use special anchors to ensure everything holds securely?

There are plenty of types of anchors online, each claimed to be the best. But what are your experiences?

Thanks in advance.

Fischer offers an app called "Dübel Finder." You can select what you want to do, and it will suggest the appropriate anchor.

I have most recently used the Fischer SX and Fischer Duopower anchors in Poroton blocks.

We used only Fischer S standard anchors for everything – both the Poroton walls and the concrete ceilings. Everything is held securely and it is significantly cheaper than using specialized anchors.

I also have the Duopower anchor. It’s quite good for securely attaching a variety of items. However, it is relatively expensive, precisely because it is more of a universal anchor. I’m not a big fan of the simple S or SX anchors; I would only use those for hanging lightweight items like pictures on the wall. For kitchen cabinets, plumbing fixtures, and heavy shelves, I would definitely use specialized M8 or M10 anchors from Würth or Hilti. If your Poroton bricks have very thin webs, injection anchors are recommended; otherwise, the Poroton might crumble under load.

Success starts with the drill. However, if you have Ytong, it is also crumbly. I drill slowly using steel drill bits, the sharp ones. This produces fine, clean holes into which the wall plug fits tightly. Once the screw is in, it holds firmly. For example, a bathroom cabinet. For example, a coat rack. Karsten

Just ask the brick manufacturer if they have any data on this. I could imagine that tests exist.

Anchor manufacturers offer a wide range of products. For very high loads, I would recommend injection anchors for bricks, even though they are more expensive. For normal loads, frame anchors are available. Be cautious about the load values provided by the manufacturers. These are usually based on standard DIN bricks, but due to energy-saving regulations, standard DIN bricks are hardly used or produced anymore. The new types simply have very thin webs, which negatively affects the load-bearing capacity. The most important thing is: turn off the hammer drill function!

What exact type of brick do you have?
