10M Pack 22mm pipe x 9mm thick Foam Pipe Insulation Lagging Wrap Roll

Just the job and a perfect fit

Works as I wanted it to. Good fit. Already split, to aid fitting on pipe.

This insulation is worth retrofitting to pipe runs in domestic hot water and heating systems, where exactly you insulate depends on which type of boiler you have.13mm wall is preferable but where pipes are run in restricted spaces (under flooring, in walls) it can be more practical to use this 9mm. A typical house may have 15-30m of 22mm pipe so measure all that is accessible and would benefit from insulation.

product arrived packaged very well in a black bin bag.9mm seemed very think but the item I received is not 9mm thick

Good value, service and delivery, though I can't raise enough fervour to get excited about foam lagging.

These work well as they fit well, and last out in the weather, where I have covered electric cable with them to make the view less messy as the cable is black and had made the fence run look untidy, whereas now the grey colour of these insulating covers has made the cable melt into the background and smoothed out the view looking out to the garden.
