Has been for a long time - the internet has only accelerated it. I think it is to the credit of the OP that they asked specific questions in a reasonably reliable site rather than relying on hearsay. I'm sure they're not the only one out there unclear about the difference between allergies and irritants and so forth. | |
| Feb 18, 2021 at 13:16 | comment | added | DevShark | I have no strong reason to be worried about allergies. I had the impression that this type of material could be allergenic. I guess I am trying to be cautious, and want to ask questions before doing the work. It seems from the answer and your comment that there is no real need to worry about the allergy, but it seems reasonable to worry about the fire risk. I think I'll go with the rock wool then. | |
| Feb 18, 2021 at 13:10 | comment | added | FreeMan | You've got a good answer, but my question for you is why are you worried about an allergic response to any of the insulation materials you are considering? Are any of these materials known to cause allergic reactions? Are any of the residents known to be highly allergic to a wide variety of materials? Until you're fairly confident that allergic reactions are going to be an issue for you/your family/tenants, don't worry about it in any of the materials you're considering for any around-the-house projects. | |

| Feb 18, 2021 at 7:16 | comment | added | DevShark | I am not entirely sure, no. I know for sure the walls are 80 cm thick, and I assumed the floor therefore would be as thick. Is that an incorrect inference ? | |
| Feb 18, 2021 at 3:37 | comment | added | manassehkatz-Moving 2 Codidact | Doesn't affect my answer, but are you sure about 80 cm? That is 31 inches - we're talking bomb shelter or bank vault thickness. And an online calculator says that a 200 square foot (which would be a pretty small house) 80 cm thick concrete slab would weigh 19.5 tons! That is a lot. Maybe 8 cm? | |

| Feb 17, 2021 at 23:15 | comment | added | DevShark | Sorry, I am not very clear. My worry is that rockwool releases small particules into the air. These particules could escape the attic (I think mainly via the tiles), and then come down in the garden and eventually in the house. I worry this could cause allergies to people living in the house. | |
| Feb 17, 2021 at 23:06 | comment | added | DMoore | You are worried that insulation will leave your attic and fall outside? What would that do? | |
| Feb 17, 2021 at 23:03 | comment | added | DevShark | @DMoore I meant to say that it's a normal, traditional tiled roof. So there are always a bit of gap. I worry that maybe some particles from the rock wool could escape from the tile and get down over time. Not sure if my worry is overblown though. | |
| Feb 17, 2021 at 22:50 | comment | added | DMoore | You need to give us a tile picture that your attic can leak from. That seems a big issue to me. | |
| Feb 17, 2021 at 22:38 | comment | added | DevShark | @isherwood I meant to say that between glass wool and rock wool, I would choose rock wool because it seems better, and the cost difference is not significant. So in my particular case, I have excluded glass wool. | |
| Feb 17, 2021 at 22:37 | comment | added | DevShark | @DMoore my worry is that even though it is sectioned off, it could leak from the tile and come back down. | |
| Feb 17, 2021 at 22:22 | comment | added | isherwood | I suggest limiting your question to that of allergens escaping the attic. "Speaking to risk" is a subjective discussion and not suited for DIYSE. | |
| Feb 17, 2021 at 22:20 | comment | added | isherwood | I don't understand disregarding fiberglass because there's something better. It's the most commonly installed attic insulation in my northern climate (to R-50 or better). | |
| Feb 17, 2021 at 22:18 | comment | added | DMoore | why are you worried about allergies? Is the attic not sectioned off from your house? In the US we would normally not be up in an attic without a mask on and would generally be doing work. I mean some people do have storage there, if that is your case its a big part of your question. | |
