Anyone fitting PIR foam insulation will know that the aluminium foil
tape used has an inbuilt determination to annoy the unwary.

Firstly the adhesive used is stronger than the foil.

Secondly, having begun life as a coil it has a readily fulfilled desire
to revert, attaching to itself with a vigour not achieved with the
intended target.

Thirdly, separating the foil from the protective backing at the torn
edge requires the visual acuity of an eye surgeon and the manual
dexterity of a watch mender.

Yesterday, at a moment of serendipity, I allowed the separating paper to
remain long from the previous run and not torn off with the foil.
Starting the next run was easy because the short stub of foil was ready
for attachment with the paper retained over the roll top under the spare
hand. Rolling out along the joint line is easy because there is a hand
free to manage the waste paper.....
