Hello,
I have an extension being built with a vaulted ceiling that has 125 * 50 rafters. The ceiling has a breathable membrane. 25mm air gap is left from top of rafters to then 100mm celotex between rafters and then 52.5 celotex insulation backed plasterboard beneath.
I have read with interest the posts and debates about downlighters in celotex etc. We will be using ceiling mounted lights but I am interested then in what is standard practice for the running of the lighting cable to the lights.
Would cabling be ok run in the air gap between the back of the insulation and then what is standard where it needs to come down to the ceiling height. Needless to say I am not doing electrics myself but am interested in what is standard practice in these situations? some form of conduit?
I am hoping to fit the insulation myself to save cost but want to know where and how cables can be run so I can leave out sections for the spark.
Thanks
