This G11 fiberglass based insulation is 1/4" thick. It's an extremely resilient and temperature resistant material, used in our V2 press applications to thermally isolate the platens.
It may also be used on top and below a cage, to increase efficiency of the heat controller, balance platen temperatures, and preserve the life of your hydraulics.
*Note, all V2 presses come standard with this insulation installed. Do not purchase with a V2*
