Looking for a visually pleasing solution for running several Cat5e cables (say 5) from downstairs (below ground floor) to the attic so that they can then be dropped to the upstairs rooms.
Problem is that all external walls have cavity insulation, so can't run the cables there, and also hate internal trunking...
Gable end is well hidden from view, so thinking about perhaps attaching some trunking/conduit to the outside wall to run them inside - something in the order of 4 metres or so.
I want to keep the cables as protected from the elements as possible. Any suggestion as to what to use? How would I cap the top/bottom for example?
Online supplier preferred (screwfix/Toolstation/TLC/etc).
many thanks.
