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. Onsite Lite Weight Concrete specializes in the installation of NVS design mix, which encapsulates the insulation board in insulating concrete, and the combination, provide positive pitch for drainage. 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.
