Safe alternatives to rockwool and fibreglass

Hi guys,

Without getting into why rockwool/fibreglass may be completely safe or not, price not being the primary concern, what would be the alternatives in terms of treatment?

Edit: If I use a thick enough foam would it work...

Without getting into the fact that rockwool/fiberglass are perfectly safe, yes, foam will work, its just very expensive on a cost vs performance aspect.

Alternatively, basotec, polyfill, sheeps wool are also good.

According to the United States Environmental Protection Agency (USEPA), exposure to some of the main ingredients of polyurethane foam – isocyanates – can cause a range of negative health effects, including asthma, lung damage and respiratory problems and damage and skin and eye irritation.

Dont have rockwool blown into wall cavity's, Not that its unsafe,, what happen is over time it settles, so the upper 1/4 of that cavity ends up hollow.

Hello, a nice alternative for rockwool and glasswool is polyester wool. It's GFR is good enough to make a pretty good superchunk.
Edit: forgot to mention that this material is completely safe and doesn't even need covering.

you can use Polyester wool

Or something like this, an agglomeration of different thicknesses of polyurethane foam

I just put this in myself a couple of days ago. It is made from recycled blue jeans.

It is completely safe [please dont try to breathe in the dust though LOL..even though...] (when ripping it or moving it it is very dusty....once it is in place it wont generate more dust though)

It is both good for you and the environment.

It functions as both thermal and sound insulation simultaneously.

I agree, it’s nice stuff. But, it’s about twice the price.

Denim does not have the well defined acoustical characteristics wools have so it is a bit of a compromize. But when using it your a Gutmensch .

It is much cheaper if you buy it by the pallet. I bought two pallets of it for around $1600.

Yea as a vegan I couldn't bring myself to buy wool....although there may be a small amount of wool in the denim insulation (because a small amount of other clothing is recycled with it) ...still, lesser of two evils.
