Abstract: There is provided an insulation kit comprising an inner waterproof layer for contacting a pipe to be insulated. On the outside of the inner waterproof layer there is insulation. Then, on the outside of the insulation there is a protective layer to guard the insulation from being damaged by rock, hammer blows, knife marks and the like. The insulation kit can be taken to the field and applied to the exterior of the pipe in a relatively short period of time. The electrical fusion wire can be activated by a voltage of 120 volts or 240 volts in about 12 amps. There results insulation around the pipe to be protected and which insulation provides an inner moisture-proof barrier; the insulation; and, a tough material to resist objects such as screw drivers, knives, rocks and the like.
