[QUOTE="shor7736, post: 520434, member: 34245"] Hi, I’m currently in the process of converting a garage into a garden room and am looking for some advice on where to run the cables for sockets and lighting. The room has a flat roof with 150mm deep rafters. I have fitted 100mm celotex in between the rafters so there a 50mm void between the top of insulation and the bottom of the roof deck. My plan was to run the cables within this gap, however after cutting a hole in the insulation, I noticed that this void gets extremely hot, especially when the sun is shining on the roof. Is it still safe to run cables in this void? My other option is to batten under the rafters (which I was going to do anyway as the distances between the rafters are odd) and run the cables in the void between the bottom of the insulation and the top of the plaster boarded ceiling. This void will be 25mm. This would be the much easier option as it would avoid removing sections of the celotex. Is it safe to run cables in the smaller void under the insulation? Thanks in advance [/QUOTE]
