Cartman was right...

[rawfuls]

Hmm, I remember reading the news article that this video was attached to.
It reported it was ____ insulated (something good is all I remember..), and was solid enough to withstand a 9.0 magnitude earthquake.
Then again, there's a difference between it should and whether or not it will.

EDIT: Found it!
It's sound proofed, thermal insulation.
Sounds pretty BA..
