INSULATION SYSTEM

Since the polyurethane foam adheres to most common surfaces, it can be installed on any roof slope. Before the Polyurethane Spray insulation can be applied, the roof deck needs to be prepared. The surface must be dry and free of oils, grease, dirt and debris that could affect the adhesion of the foam. In some cases, a waterproofing membrane or chemical waterproofing is applied on the roof for extra protection before the spray foam installation. The Polyurethane is then sprayed onto the roof surface rising up to the required thickness. Once it hardens into foam, a thin layer of plastic sheeting (separation layer) can then be placed over the insulation along with a layer of cement screeding reinforced with weld mesh or a gravel layer with cement/ceramic tiles. As a final layer, the Master Thermoshield Polyurethane Spray insulation can be covered with UV resistant paint for a long lasting result.
