Owens Corning Insulation

[Jeffrey R. Jonas]

This would be a great subject for Nick to write an article on... all the common types of insulation we run accross, with descriptions and quality photo's... Hi-Res close-ups... and I'm talking close, as in macro... not three feet away. Most all pic's are not close enough for proper detail and identification.

How do you tell the difference between white fiberglass, and white mineral wool?

In my neck of the woods there's always a data plaque at the hatch telling what kind of insulation and required R value / thickness.
