Heated Bed Insulation

Melamine is awesome and hard to beat, can easily get me to 110C now when I couldn't make 100C with silicone sheet (conductor not insulator!))
It's a good idea to insulate the underside of the heatbed in order to get a faster heat up time and a overall better thermal performance. For higher temperatures, an insulation might even be required.
Solutions found to work are:
- Cork plate (more dense wood (eg plywood) is better than nothing, but tends to conduct heat away too quickly).
- Cotton batting.
- Rescue sheet, see e.g. Robert's Heated Bed ie the silver or gold rescue blanket used by hikers.
- Glass fibre soldering/plumbers/welding mat (approx £3 on ebay)
- Silicon cooking mat
- Teflon cooking sheet (doesn't insulate very well, but doesn't melt/burn, and can keep glass fibre contained)
- Melamine Foam (Excellent insulator but thinnest is typically 1/2", easily laminated to heated bed with 468MP tape. Doesn't burn and high temperature tolerance.)
