Lightweight Insulating Concrete Roof Systems

Our reusable Lightweight Insulating Concrete Systems are available in four mix designs. Each encapsulates insulation board, bonding the system to the substrate. The systems are typically reroofable, therefore not contributing to solid waste disposal.

The reusable, high performance roof insulation solution

Siplast Lightweight Insulating Concrete Systems combine lightweight concrete and expanded polystyrene foam. They provide a smooth, monolithic surface ideal for roofing, and help to prolong the life of the roof membrane by lowering membrane temperatures. Our systems address roof design goals such as slope-to-drain, moisture resistance, compressive strength, stability, and mechanical fastening.
