NVS and Insulcel are composite systems that combine the unique properties of Lightweight insulating concrete (LWIC) and premium expanded polystyrene (EPS) foam insulation. The polystyrene insulation board can be installed in thicknesses necessary for high insulation values and in a stair stepped fashion, facilitating a positive slope to drain.
Poured 25 mm (1") for NVS and 50 mm (2") for Insulcel thickness over EPS insulation, these LWIC systems have been engineered for use over non-slotted or slotted galvanized corrugated metal decks (Insulcel), structural concrtete substrates and, where appropriate, over existing roofs in recover applications. These systems provide high performance solutions to industry concerns that include moisture resistance, high compressive strength, dimensional stability, fire and wind resistance, stable R-values and environmental safety. As a reusable resource LWIC also provides LEED values and is re-roofable.
NVS concrete is a 1:3.5 volume ratio of Portland cement to patented NVS Concrete Aggregate.
INSULCEL concrete is a mixture of Insulcel-PB pregenerated cellular foam and Portland cement / water slurry.
