Hi all

I hope to lay electic undertile heating to a sound, dry concrete floor
that has a 10mm hard bitumen (asphalt) covering, which is in good
condition and is level. This will not be the sole heat source, but
merely for comfort.
Will the bitumen melt?! I don't want the extra thickness of an
additional insulation layer such as 10mm Mortex. Any advice
appreciated.

Thanks
Noah

Noah, Bitumen is funny stuff and may well have long term slow effect on the
insulation of the UFH. I would ask this question of the manufacturer of the
system you plan to use.
