attic insulation identification


Hi I am, trying to identify some insulation in a home that was built in 1910. There is no access to the attic except for a small opening in the bathroom where an exhaust vent is installed. I was able to pop my head through and looks like 6-7 inches of insulation. I am not exactly sure, so I was hoping someone might be able to ID it for me. I have attached a pic. It's kind of wool like and fibrous.
Thanks

Looks similar to cellulose.

If there is 6-7" of it, it certainly isn't original to the home.

I don't know how they got up there to insulate as the only opening I have found is in the bathroom where the ceiling fan is. I am surprised that there is 6" of insulation. It's hot in the summer and cooler in the winter on the 2nd floor.

Is it worthwhile to add more insulation?
thanks

Yes.

Most homes and climate regions recommend 12-14" of a loose fill insulation.

It should be that big a deal to make a new acess hole. Sometimes there in attic ceilings so they do not show as much.

What type roof venting do you have.

It appears to be rock wool, second photo, hold "control key" and hit "Plus key" repeatedly, use "arrow keys" to find it on page;http://inspectapedia.com/interiors/R...Insulation.htm
Hold control, hit "minus key" to reduce again.
