Step Three

Measure the circumference of the exhaust pipe to be insulated fig.7. Mark the same measurement on the front of the Thermolastic tape, (over the insulating section) at an angle as shown in fig.8. Cut with scissors as fig.9
Fasten the tapered cut end of Tape to the exhaust to start. Spiral warp the thermolastic tape around the pipe keeping it under tension and overlapping the foil layers. The insulated section should butt up against the adjacent insulated section as in fig.11. Fasten with adhesive tape to secure. Subsequent layers should be spirally wound in the opposite direction as fig.12
