Hi,
I have a loft ring main, I am hoping to clip the cable to the floor joists, and where it crosses another joist (ie the solid blocking) trail it under the blocking/joist and back up the other side continuing to clip as I go (rather than drill a hole), where the cable is pushed under the 45mm width joist it presses against a Knauf Earth wool mineral quilt, this situation also occurs where the cable will run under a 203mm steel beam (ie it presses against the insulation one side and steel t'other).
Is this a problem regarding de-rating, its only 45mm, and the 203 steel would actually act a a heat shunt as thats always cool to touch.
Thanks
