Inverted roof Insulation
IsoBoard is laid above the water proofing layer and secured in place using ballast, to prevent flotation or wind uplift. The ballast layer can be gravel, paving stones or a concrete screed. The water proofing is protected from the sun and weather by the IsoBoard, rendering it practically maintenance free. The thermal mass of the concrete slab is maintained at the internal temperature of the building, protected from daily variation, helping to maintain a constant temperature within the building. Inverted Roof insulation can be installed onto a new building, or as a retofit solution later. IsoBoard excels in inverted and Green Roof applications, as it is the insulator least affected by water.
