heat insulation
does any body know any material that we can lay over roof
and it will protect roof from heat of fire ball or other extremely hot gas emission?
asbestos blanket, rock wool insulation with a steel plate cover, clay tile with air space beneath.
heh...you mean like a meteor? or a politician? |
