Fiberglass insulation help please

[bchee]

This is probably a long-shot but I'll ask anyway

Found some fiberglass insulation on CL, seller says they are 5 ft tall rolls.
I'm assuming they are commercial use or something like that.

Do these rolls come in a standard size? Or a standard sq ft coverage?

Seller is unsure of dimensions.
Figured I would ask here to see if anyone knew, in case there is no info label on the roll, and I can't unroll the whole thing to measure it. THANKS

Standard size would be 16 inches wide and 8 feet long. To fit a normal wall cavity. 24 inch wide would be for a ceiling. Kraft paper backing should be there for a vapor barrier. Some deals aren't very good after all.

I don't think this is a standard residential size. I think it's commercial use cause it's a huge 5 ft wide (tall) roll.

The picture isn't very good (CL ad) but imagine that roll being 5 ft tall.

I think it is a commercial OC product - you should be able contact your local supplier and they could tell you how many sqft per roll - as manufactured.
see link for specs....

It turned out to be R-19 for 20 cents per sq ft. Did I do ok?

just a roll, not faced or any of that comfortable to handle stuff.

If you already bought it, it's irrelavent if it's a good deal or not.

If you can get those rolls into your attic and you already have FG batting, I know what I'd be doing with them. I'd roll them out across the rafters and blanket the attic with a second layer. Like the picture in the link.
