I've got a mobile, old style electric towel rail on a plywood board. I (almost) forget the original purpose but I think it might come in useful this winter.
The plywood board is faced with cooking foil which is useful but very easily damaged due to it's thinness. Can anyone please recommend a source for heavy duty foil, where I don't have to buy a big roll? The area I need to cover is only 1Metre x1Metre.
