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.
