Nope, it was autocorrect.
I have Adobe Acrobat.
Just seems a bit clunky.
Cables in external cavity walls are not allowed. Another reason why not, is that a 3rd party might hit them when drilling through wall to install TV cables etc
And they wouldn't hit them if they were chased instead?
Prescribed routes.That's what zones of protection are for
Ahh, Irony, nice.Thats that then. New builds should have all the cables run in the cavity, wouldn't have to worry about sheathing or clipping the cables.
I think the irony is that none of the things she quotes in her song are ironic?Irony?
Hmm...don't think I'll be phoning Alanis any time soon...
Re drilling through cavity walls. Was just an example. Many Sky installers drill straight through cavity walls. Gas plumbers also.Can you give a reg number for that mate?
Would someone drill through the full width of a brick (102mm) to fix a TV cable?
As for Reg No., no, I don't know. But correct me if I'm wrong, has not installing cable within external cavities been banned for years?
There’s no prohibition in BS7671 against running cables in cavities.
In fact BS8436 cable is designed for use in building voids and BS7671 lists installation methods 40 to 44 as being writhing building voids.
Even if it is, it's governed by building regs/good practice which preclude bridging the gap.
Interesting, I wouldn't class an external cavity wall as a void myself. Cables can not be supported in cavity walls. Insulation also cavities.
