Helloooooo All,
What is the preferred TYPE of cable to be run in a foundation dwarf wall cavity of a new domestic conservatory? The cables can not be run from above as the walls are glazed. The cables can not be run from below as there is underfloor heating to be installed.
The main concern is any adverse effect of any unknown thermal insulation such as polystyrene that may be added into the cavity upon the cable insulation.
Thanks,
Z.
