The Green Cable Concrete for perfectly even heat

Since it is embedded directly in concrete, the Green Cable Concrete uses the concrete mass to absorb, retain the heat and radiate it evenly in the room. A warm basement floor? Yes, it’s possible!


  • Designed specifically to be embedded in concrete; installed directly in the concrete slab during a new construction or under a concrete topping when installed over a plywood subfloor
  • Increased thermal mass effect and heat is spread more evenly due to the exceptional heat storing and releasing capacity of the concrete mass
  • Ideal complement to the Concrete Mat Xpress during installation in irregular shaped rooms with objects to circumvent
  • Compatible with most floor coverings
  • Energy savings of up to 28%*

  • Free of electromagnetic fields**

  • Does not dry out air or spread dust and germs

  • Requires no maintenance

  • Designed for installation in wet environments

  • Lifetime warranty when installed by a FLEXpert certified installer or a FLEXboutik through a certified installer (otherwise the standard 25 year limited warranty applies)

*In a room heated by a FLEXTHERM floor heating system. **Based on the installation instructions included in our FLEXTHERM installation guide, the recorded EMF measurement is considered insignificant (between 0.25 mG and 0.5 mG).
