Fiberglass insulation or fiberglass free
 
We are not looking forward to putting up Fiberglass insulation. Has anyone tried the fiberglass-Free insulation? It is suppose to be a soft and itch-free alternative. It is somewhat higher in cost. Is it as good as the fiberglass? Any information would be appreciated.

Thare are probably dozens of types of insulation other than fiberglass. Since you did not specify what type of insulation you are considering, I can't comment on it. But I just finished putting rockwool batt insulation in my attic, and went in fine. I still wore long sleeves, long pants, and a mask, but actually, neither fiberglass nor rockwool really bother me much.

We are putting up batt, wall insulation. Thinking about that fiberglass just makes me itch. LOL Dow has a fiberglass free, formaldehyde free batt insulation but it cost more. We have heard that fiberglass fibers could get picked up by your furnace and may cause furnace problems.?? We will blow the attic insulation in but haven't decided on what type yet. Any and all suggestions are appreciated.

The Dow links to the spec sheets were dead when I tried to look at them, but it says it is made of PET, which is what the big soda bottles are made of. I never heard of insulation in the walls causing problems with a furnace ( and I don't believe it ). Up North, we would have a vapour barrier (plastic sheet) between insulation and the inside of the house anyways. Not sure how things are done down there, but somebody in the forum will help out with that. You can't fit much insulation in most walls, so I would be looking simply for the most R-value you can afford to fit into those walls. Itch factor would be on the bottom of my list when selecting insulation. The PET must be treated with a fire retardent, the way cellulose is, but I know that the rockwool in my attic is made from basalt rock, and will not burn at all.

there is also insulation made from recycled denim. its more money than regular insulation. it also has better sound dampening properties than regular insulation.

Yea, we saw that on the net, not in the stores. The Dow Safe Touch is not in the stores here either, it would have to be special ordered, which is not a big deal. Any one have any experience using either one?

Fiberglass is not treated for fire resistance. - It just melts.

It does not absorb moisture but it hold moisture for dirt dust and wood to support mold.
