Re: Roof Insulation (Was Re: Halogens for thickies)

Mmm.. makes me wonder how I know that the conduit isn't made of PVC
as well ! I suppose wrapping the actual cable in insulation tape might
be the best option.. but a pain to do :)

>IIRC any cables (lighting circuit) need to be protected in plastic
conduit and not allowed to touch the insulation. I assume that this
is because of potential heat build up in the cable causing the
JABSQUEEZE to melt ? If so I'm very wary of fitting halogen recessed
lights into it. Maybe I need to build small "boxes" into the
ceiling at
each light position ?

I believe this is because, for expanded foam polystyrene products, contact
with PVC material causes the oils to leach out of the PVC - you see the
effect when VCR's/DVD players/etc come packed with foam polystyrene ends
and
the mains cable has been in contact with them for a couple of months whilst
it sits on the shelf.  Imagine that over a couple of years...  Think
extended contact makes the insulation brittle..??
