Self-regulating heating cables for roof & gutter snow melting and de-icing.

Raychem GM-2X heating cables provide roof and gutter snow melting and de-icing for following applications:

  • Roofs comprising standard roofing materials, including slate, shingle, tar, wood, metal, and plastic.
  • Gutters of standard materials including metal and plastic
  • Drainpipes of standard materials, including metal and plastic.

The heating element of a GM-2X consists of a continuous core conductive polymer extruded between two copper conductors. As current flows through the core, the heating cable regulates its heat output in accordance with ambient conditions. The self-regulating feature eliminates hot spots and results in better temperature control to protect roof and gutter materials.

The GM-2X heating cable is ideal for more economical and less demanding applications. If the roofing material is bitumen, GM-2XT should be used to ensure maximum abrasion, chemical and mechanical resistance.
