I’ve been asked quite a few times if BeWarmer could supply the correct type of underlay for the RugBuddy under rug heater. It sounds an easy thing to do but there are various factors to consider.
On top of this, if the hard floor isn’t wood or laminate, then you’ll only get the best performance if the underlay also insulates. After all, you wouldn’t want all that lovely warmth disappearing down into the floor.
(Insulation isn’t generally a problem with carpet, wood and laminate floors as these nearly always have their own underlay.)
I’m still working on a solution for an insulating underlay for the RugBuddy under rug heater but, as I’ve said before, it needn’t be expensive. 6 – 7 mm (or more if you’re not worried about the thickness) of Polyurethane (PU) foam works well.
