SuperFOIL SFUF is a multi-layer foil insulation for use with solid and suspended floors. It can also be used to insulate in other areas, including walls and ceilings. Consisting of 13 layers of reflective foil, thermo foam separation layers and topped with a PE layer, SFUF is the ideal for use with hot water underfloor heating systems.

SFUF reflects heat back into the room, at the same time improving airtightness and resisting the passage of moisture. It vastly improves energy performance and also reduces impact noise.
