What is this called and where do I buy it?!

[Jon Bon]

So I need to insulate my basement to pass inspection.

In the attached picture there is a white fiberglass blanket attached to the walls. I want to use this blanket roll because it is likely cheap and easy to use. However I cannot find the proper name of it, nor do I know where I can buy it. I don't think it is that complicated, lots of houses in my area have this sort of basement insulation. Id prefer to have it shipped to a big big box store if possible.

Help me out hive mind!

I don't know what it is, but if you show that picture to someone in the insulation aisle at Lowe's or Home Depot they'll know.

That is fabric faced metal building insulation.   Some suppliers include; Service Partners, Guardian, Therm-All, etc.
Just google metal building insulation suppliers and some will pop up.

As mentioned, that type of insulation is often used in metal buildings and pole barns. Looking up "pole barn insulation blanket" should get you on the right track.

Menards sells something similar if you have them in your area:

If you find it at a "big box store" it will most likely be of an inferior quality and overpriced compared to where the Pros get it.
