NVS Lightweight Insulating Concrete System
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.
Lightweight Insulating Concrete Systems
Siplast Lightweight Insulating Concrete Systems combine the unique properties of lightweight insulating concrete and Insulperm premium expanded polystyrene foam insulation board. Siplast Lightweight Insulating Concrete is available in four mix designs: ZIC, NVS, Insulcel, and Zonocel. The four designs represent a range of compressive and tensile strengths, allowing a choice of system based on substrate and specific project circumstances. Each design encapsulates the insulation board in insulating concrete. This process provides fire protection, prevents air infiltration, and bonds the total insulation system to the substrate. Unlike rigid board, Siplast Lightweight Insulating Concrete is reroofable, and therefore a truly sustainable insulation solution.
