which concrete composite is best
« on: April 27, 2002, 01:35:38 AM »
I am considering building a dome home.  I want to keep outside noise outside (freeway w/ slow on ramp traffic)
One contractor builds a fabric form exterior, a middle layer of 3" Polyurethane and then 3" of concrete on the interior wall.
The second builds 3/4" concrete on the exterior wall with 9" E.P.S. insulation on the interior wall.
I guess the mass of the 3" makes it superior but I like the other house better.  How much soundproofing will I loose if I opt for the second builder?

THANK\YOU!!!!!
