TERMOFOL SUPERTERM 6 mm Insulation Board – for heating films and floating floors

TERMOFOL SUPERTERM 6 mm is an XPS insulation board designed for use under floating floors and in electric underfloor heating systems with heating film. It creates a stable layer between the substrate and the heating system, reducing heat loss downwards and improving the heating performance.

The board has been developed with vinyl floating floors in mind. It also helps to compensate for minor, local unevenness in the substrate up to 0.88 mm – making it easier to prepare the appropriate surface before floor installation.

A good choice for heating film

SUPERTERM can be laid directly on the prepared substrate and then serve as a base for TERMOFOL heating film and floor panels. The board is 6 mm thick, allowing for an additional layer of insulation without excessively increasing the overall height of the floor system.

Made of XPS, it provides a low thermal conductivity coefficient of λ = 0.035 W/(m·K) and high compressive strength Cs ≥ 400 kPa. This is important for floating floors, where the underlay is subjected to loads transferred by the layer of panels.

Main advantages

• designed for floating floors, especially vinyl,
• suitable for systems with TERMOFOL heating film,
• reduces heat loss towards the substrate,
• helps increase the efficiency of underfloor heating,
• levels local unevenness in the substrate up to 0.88 mm,
• high compressive strength Cs ≥ 400 kPa,
• thermal conductivity coefficient λ = 0.035 W/(m·K),
• made of extruded polystyrene XPS,
• thickness 6 mm,
• single board dimension 120 × 60 cm,

TERMOFOL SUPERTERM 6 mm is an underlay designed to create a stable and well-insulated base for floating floors. In combination with heating film, it helps to reduce heat loss to the substrate and utilize the energy of the system where it is needed – for heating the floor and the room.

Application under underfloor heating

TERMOFOL SUPERTERM insulation boards are designed for use under heating foil in electric underfloor heating systems with floating floors. They perform well in houses, apartments, and standard utility rooms, under laminated, vinyl, and appropriately selected wooden floors.

They provide an insulating layer between the substrate and the heating foil, limiting heat loss towards the substrate, leveling minor irregularities, and improving the acoustic comfort of the floor.
