Sturdy, flexible and perfectly adapted to take on unforgiving winter storms, ProtecTHERM heating cables are suitable for various types of roofs, as well as metal pipes and plastic pipes. Wrapped around pipes or attached in straight lines to pipes circulating outdoors and in unheated installations, ProtecTHERM heating cables prevent liquid from freezing inside the pipes. On roofs, heating cables melt ice and snow and create a path for water to drain to prevent potential damage.
