Self-adhesive backing

The backing mesh is made of strong, durable nylon with a self-adhesive backing. This allows for a quick, secure installation and avoids problems due to the mat floating or moving in the tile adhesive.

Stitched cable

The heating cables are stitched to the durable backing mesh with a special heat resistant thread. This ensures the element spacing remains uniform, guaranteeing an even distribution of heat and eliminates the opportunity for cold spots, which is a common problem with lesser quality mats.
