Well, in all the years i've been in this industry, i've never seen a recommendation from a cable manufacturer stating that their cables were only good for 10 years!!

It was well known by all, even in the very early days, that PVC was basically immune to most environmental conditions as well as many chemical substances. The only problem that i can think of, ...was the old polystyrene insulation material used in roof lofts etc. Which is no longer a problem with modern polystyrene building insulation materials. That and working PVC cables at, near, or below 0c.

We used it in the 70s to wire maisonette's. For the ring, it was masonry nailed to the concrete slab, then screed was laid over, for the lighting, it was wired from the maisonette above as a loop in system. They were delivered to site as a kit box for each maisonette, (wire,lights,switches,sockets,etc,etc,) The coils came in pre-cut lengths with a dedicated code, ie. Flat 213 C1P (P=Power) Flat 213 CIL (L=Lighting) I know painting numbers, :smilewinkgrin: and all laid to a pre-determine design (NO cross overs) No underfloor heating.
