DEVImat™ is an extremely high-quality, 360° fully screened self-adhesive all-in-one mat with FEP insulated conductors and a red PVDF outer sheath (non UV stable). The round profile, low height (only 3.5 mm) and robust construction ensures a fast, simple and safe installation perfect for renovating existing floors.

The cold lead is an installation cable with solid conductors ensuring fast installation. A clearly visible connection avoids accidentally installing the heated cable in the wall. To ensure a long life-time, all cables are minutely inspected including tests for Ohmic resistance, high voltage and material controls to ensure the quality. This means that we are proud to supply our full floor extended DEVIwarranty™

A 20-year full service warranty is valid for DEVI electrical heating cables and mats.

You can rely on the DEVI quality; but, in the event of failure, the DEVI cables or mats, which can be tracked back to a manufacturing defect in the DEVI product, can be repaired or replaced free of charge.

Not only does this warranty include costs of reparation or replacement, but also installation and floor materials, such as damage to brickwork and tiles.

The installation of DEVI products must be performed by an authorised installer in order to apply for this warranty, and the warranty certificate has to be stamped, signed, and provided.
