Insulation around pipes in fireplace
Hello
We have a fireplace where the round metal pipe goes up through the upper floor and through the attic up to the chimney. When we had the fireplace inspected, we received a remark.
Looking up in the shaft where the pipe goes, you can see that there is insulation around the pipe at the top. The chimney sweep remarked that we should remove this insulation. We were not given a burning ban and interpreted this as something we should do, not must.
Now it turns out that it is very difficult to access the shaft. Everything is quite stupidly built in, and I'm now trying to find out if it's really the case that the insulation around the pipe is a big problem that needs to be addressed. The fireplace has been pressure tested, but the chimney sweep mentioned that any leaking gas cannot be ventilated out because the insulation is in the way.
Does anyone have any knowledge/advice on this? For a beginner like me, one naturally wonders if there are fire risks since the insulation is against the pipe. Everything is built in 2004, so it's relatively new.
If I have understood correctly, a chimney fire can make the pipe very hot, but at the same time, I find it strange to place insulation in a way that could pose a fire risk. If I remove the insulation, on the other hand, water, moisture, and cold can go straight into the house.
I would be very happy if someone could clarify this for me and give me advice on what I should do.

Hello!
I'm not sure if this will help, but when I installed a stainless steel pipe in my chimney, it was important to "insulate" to maintain the temperature of the smoke gases and prevent condensation. However, the insulation was something I believe was called vermiculit, a gray, very light material that looked like pea-sized stones. This filled around the pipe all the way down to the connection at the boiler. Above this, I built between the flue and the pipe to prevent moisture from getting in. All this was then approved by the chimney sweep. So regarding ventilating out leaking gases, I don't understand; I think you should contact the chimney sweep again and ask what he means you should do, after all, he is the one who needs to approve any changes.

Hello, I'm not entirely sure what the chimney sweep means by saying the insulation must be removed. Around a chimney, there must be a certain free space of non-combustible material. Often, the "pipe" is usually enclosed with special insulation with a metal mesh around it. Is there a metal mesh around the insulation you're looking at in the shaft?
What Micke59 is talking about with värmekulit is when you insert a pipe into an existing chimney, like one made of brick, and then fill the space between the pipe and the chimney with värmekulit. In your case, I interpret it as you only have a chimney made of metal, a round pipe.
