Hi All,
I'm having a log cabin wired at the minute and have run into a slight problem with the cabling. Before anyone asks, yes this is being carried out by a Part P qualified electrician!
I want to run the cabling in the cavity between the two log skins but the cavity has expanded polystyrene insulation. Due to chemical interaction between PVC sheathed cable and polystyrene, you can't put this cable in direct contact with polystyrene. The solutions are to use suitable conduit or wrap the cable in polypropylene or polyethylene tape. Using conduit isn't practical as the space between the cabling and insulation is tight allowing just the cable up between the log skin and insulation. Using tape is possible but fiddly to get an even coat round the cable and avoid any bare spots exposing the PVC sheath.
I've come up with an idea which may work and would appreciate anyone's thoughts. I've looked around and found heat shrink sleeving made from polyolefin. This would be easy to slide over the cable and heat seal making a perfect barrier between the PVC and polystyrene.
Anyone see any problems with this?
