NVS System

Lightweight Insulating Concrete Systems


The NVS mix is a 1:3.5 ratio of Portland cement volume to NVS Concrete Aggregate volume.  NVS is engineered for use over non-venting substrates and in reroofing and re-cover applications.  Because of its higher compressive and tensile strengths, NVS requires only a 1-inch minimum thickness over the top of the Insulperm Insulation Board.  Click on a selection below for detailed information on the NVS System.
