How Insulation is Made

[GianniFocaccia]

The Science Channel is currently running a (How It's Made) segment on how Stone Wool Insulation is manufactured from basalt. The short video here only shows the first portion of the piece, but it's pretty interesting.

That was interesting. There have been a couple threads recently about this stone wool and the various names it goes under. I knew it as rock wool and saw it as loose insulation placed in cavities to insulate houses. I'd like to use it in place of vermiculite (placed outside the ceramic layer over the dome) if I could find a local source.

At one time "rock wool" was one of the terms used for asbestos insulation.

I'm SO glad you could mention that

It seems like names for insulators have been regional and unstandardized.
