I received a response from the board, and they seem to want me to use cellulose fiber... But it only has a lifespan of 20-30 years, and with my house, I aim to live longer than that.

Mineral wool shouldn't be an issue when we're talking about the intermediate floor between two levels, right? I understand the problems in the attic, but that's not my case. And the roof is insulated with mineral wool...

How should I argue/think? Again, thanks for all the help!
 
seems to want?

require them to request it in writing.

otherwise, go with mineral wool, cheapest!
 
Not entirely clear yet, chasing them. The problem is that I was naive and ordered materials that will arrive on Friday, maybe I can cancel.

But if it is a requirement, should I take it in writing and accept or should I try to further argue for minerallullen?
 
Why would it only have a lifespan of 20-30 years? I see no reason why it would hold up worse than mineral wool. If it's not dry, no insulation will fare well.

Cellulose is heavier and more compact, meaning it dampens better (both sound and draft), and it results in less moisture change from the current construction, so the association has a point.
 
I don't think they can demand that, what does the association's bylaws say? I guess there's nothing written about which insulation material should be used.
I would probably talk to the board immediately and tell them that you have already ordered mineral wool, I find it hard to believe they will oppose...

I am also a bit surprised that the board is knowledgeable about different types of insulation...
 
What quick responses! Thank you!

After googling, that's what I found. And also an argument used by mineral wool, i.e., it lasts as long as the construction. I'll check if I find the pages :)

Yes, it's a good point, but in this case, it almost becomes a bit too theoretical because should it really be an issue between two heated floors?

No, nothing in the statutes, but the floor construction is probably the association's responsibility, and therefore I probably need their approval for any changes, or am I thinking wrong?

I don't want it to need refilling. I have a floor joist on cc40, yes, it will be a hell of a lot of holes in the future to fill. I want the oak strip parquet that I'm planning to lay to last a long time...

Or am I thinking wrong?
 
What do your statutes say about floor slabs? Isn't it the association that "owns" the floor slab and thus the insulation?

I seem to remember that when there was water damage in an apartment in my association, the association covered the replacement of the insulation and the member covered the repair of the surface layer (even though it was the same construction company that did the entire job).
 
That's how I interpret it too.

To make a long story short, I'm leveling the beams to be able to lay new flooring. And while I'm at it, I want to try to address the problems with the cold floor. It's obvious when the insulation is gone that the wind blows right through the insulation. So I got help here with what I could do and pressed the board to allow it. Now it seems like I can proceed with the original plan, so thanks everyone =)
 
arkTecko, if I understood you correctly, are you advocating for cellulose insulation? Do you think there is any significant risk with mineral wool?
