aying underfloor heating mats in my log cabin.
I have 120mm tounge & Grove boards with 10mm insulation boards fixed down with insulation board washers.
I have taped the joints with gaffa/duck tape and used 15mm expansion tape around the sides to allow for wood expansion on the self leveling compound.
Anyway my question: Do I need to cover the metal washers with silicone or something as I don't know if any conductive materials will have any adverse effects on the heater mats/element.
Also I was told to cover the insulation boards with a foil sheet to improve heat transfer upwards but again will this have adverse effects on the mats/element.
Hope someone can help, cheers.
