How to do, roof by chimney

[ankan_84]

Hello. Today I tore down a wall and will expose the chimney that was previously enclosed. To my great surprise, I see when I take down the wall that the studs have been nailed against the chimney, which can hardly be optimal. But my question is, how should I deal with the new ceiling that will be installed? Can I butt it against the chimney and put a trim around it? How much wood is allowed against the chimney??

Hope you understood the question...

We also have a chimney in the house, so when I was putting up our ceiling in the first room I renovated, I called the chimney sweep to check what was required. He then told me that combustible material should be at least 10 cm from the chimney. However, we have rafters that are about 2 cm from the chimney, and I asked what I should do there. Since it was an existing construction, I didn't need to do anything, but he suggested that I could put some mineral wool in the gap anyway. He suggested that for the wall facing the chimney, I should cover the stud closest to the chimney with a couple of strips of minerit board to protect them if I couldn't place them at the correct distance. Oh, forgot to mention, the end grain of the sparse panel can indeed touch if necessary to provide stability for the ceiling covering. You can also pull the diffusion plastic against the chimney, but a little tip is to use sauna foil at the chimney because it withstands heat better.

We also have a chimney breast in the house, so when I was about to install our ceiling in the first room I renovated, I called the chimney sweep to check what was required. He told me that flammable materials should be at least 10 cm from the chimney breast. However, we have rafters that are about 2 cm from the chimney breast, and I asked what to do there. Since it was an existing construction, I didn't need to do anything, but he suggested that I could put some mineral wool in the gap anyway. For the wall against the chimney breast, he advised cladding the stud closest to the chimney with a couple of strips of mineral board to protect them if I couldn't place them at the correct distance. Oh, right, I forgot, the end grain on the sparse panel could indeed contact if necessary to provide support for the ceiling covering. You should also run the diffusion plastic against the chimney, but a little tip is to use sauna foil near the chimney breast as it withstands heat better.

Great, thanks for the response. I'll follow your advice

But to be on the safe side, go ahead and give your local chimney sweep master a call to make sure there aren't any specific rules that apply just in your municipality. Better to check beforehand than to have to redo it later

Rules are probably good, but isn't any consideration given to how the chimney is constructed?
Ours has been wallpapered directly and it has been like that for 50 years without coming off, so I'm not overly afraid to install framing close to it
Without looking more closely, I assume that the flue goes in the middle with the other channels around it.

one has tightened the rules in recent years, which has led to a lot of fire bans and renovations. Therefore, they can become quite picky about something that was approved earlier, so the best advice is, as mentioned, to talk to your chimney sweep master.
