We just had a new roof put on our house. We had a continous ridge vent installed on the roof. Now I will be insulating the attic. Our house is almost 100 years old and the only insulation in the attic is the pellet stuff just laying on the floor. I have been told it is called “vermiculite”. What ever it is called, it makes me choke when I breath near the stuff. So I was going to buy some insulation and insulate the rafters of the attic. Is this ok with the ridge vent along apex of the “A” of the roof.
Also, should I try and remove that vermiculite? I honestly can’t understand how that can have any R factor in it.
