Cohousing-L Mailing List: Re: Marmoleum vs. Hardwood

[Robin Allison (ecohousing]

We used Marmoleum on a suspended concrete floor to reduce sound transmission
to the house below.

2mm Marmoleum on 2mm corkment underlay increased the theoretical IIC (Impact
Insulation Class) rating from IIC 43 for an uncovered concrete floor to IIC
63. This is similar result to what would be acheived using parquet flooring
or 6mm cork.

We wanted a thin covering that would not insulate the concrete floor from
the passive solar thermal gain. We've been happy with it so far (in
residence for 4 months only). Acoustics within the house was not an issue
here so I don't know how marmoleum performs for sound absorption within a
space.
