What is Tuff Cable and what is it made of?

Tuff Cable is a low-voltage electric radiant heating cable made from a specially-engineered copper heating wire (approximately 10-gauge), manufactured by Heatizon Systems. It is chemical and gasoline resistant, comes with footage marks printed along the cable for easy layout verification, and is designed to always be embedded in a heatsink material — such as concrete, asphalt, mortar, stone, pavers, or Heatizon’s Invizimelt Panel. Tuff Cable is a cut-to-length product, giving installers precise control over system sizing without material waste.
