DIY Guide For Pipework Insulation

1. Start by wrapping the bandage twice round the end of the pipe next to the tank. Hold the turns in place securely with string or tape.

2. Wrap the bandage round the pipe in a spiral. Make sure That each turn overlaps the previous one by at least 10mm (3/81n). Don’t pull the bandage too tight. 3. Whenever you finish a roll of bandage and start a new one allow a generous overlap to prevent air circulating between the turns of the /oin. 4. Finish off the pipe in the same way that you started, with an extra turn of bandage. Lastly, check the pipe to make sure all the insulation is secure.

5. Fitting split-sleeve insulation is simple. You just prise apart the split and slip the sleeve over the pipe. Use tape to keep the sleeve in place. 6. At bends. where the sleeve tends to come apart, tape the split length ways. Tape the sleeves, too, whenever you join one to another. 7. At tees, first cut a notch’ from The main pipe sleeve. Then shape the end of the branch pipe sleeve to fit and slot it into place. Tape the join. 8. Use split sleeve insulation on pipes that would be hard — or impossible — to fit with bandage. Slip the sleeve over the pipe and slide it into position. 9. Sleeve and bandage insulation can — and sometimes must — be used together. A stop-valve, for example, can only be properly fagged with bandage.
