Warmup Insulated Underlay is a thin polystyrene insulation barrier with a foil backing. It is designed for use under the Warmup Foil Heating system. It is installed between the cold subfloor and the Foil Heater which reflects the heat upwards making the heating system more efficient. The Insulated Underlay has effective acoustic properties to reduce contact noise and the foil backing acts as an effective moisture barrier.

Installation is quick, clean and dry, making it an easier option for installers. It is installed foil side down, the protective film from the self-adhesive strip is removed and the underlay is stuck to the subfloor. The next section of underlay is then laid with self-adhesive strip overlapping the foil to act as a moisture barrier.
