Cable Runs In Loft

[ban-all-sheds]

Hi,
Well I would not say that they are buried in insulation, as I have lifted all wiring (sitting on top of insulation), I was then going to board the loft with chipboard, therefore the wiring would be touching the chipboard along with the insulation.

What do you think!

To qualify for Method 15, the "thermally conductive" surface must have a u-value of at least 10 W/m²K. Chipboard is only 2-3....

Whats plasterboard?, OOI?

first one to say "well its plastic sandwiched between paper.." gets a slap with a wet fish

Could you supply me with a link to method 15 etc, also I am trying to find where the appendix 4 charts/diagrams are

Many thanks

Why would anyone say that? It's plaster sandwiched between paper

9.5mm baseboard is about 16.

Hi,
So touching 9.5mm plasterboard one side and touching insulation the other side of a wiring route is acceptable!

Also a link to the method 15 etc and appendix 4 diagrams would be useful

Many thanks

Is this not covered in the IEE wiring regulations 16th edition?

Sorry I meant the one from Jan 2005 (doc P)

That's not the Wiring Regulations.

It's not even a guide to the Wiring Regulations.

It's a guide to one part of the Building Regulations.

The book shown above with the brown cover is the Wiring Regulations.

Sometimes I really do think my hands ignore what my brain tells them to type in lieu of something that sounds some-what similar

Thanks for that, would you say that for a solution, a 1" air gap would be sufficient? Also would wrapping or laying wires in or on silver foil would help to disperse heat generated?
