Where can I buy sheets of cork?

Where can I buy sheets of cork?

I ordered a roll today from Amazon, I expect I might have to cut it and let it flatten out for a while though..

[adamfilip]

why did you decide to add the alum foil under the glass?

[old man emu]

why did you decide to add the alum foil under the glass?

I put the aluminium foil between the heatbed and the glass to try to ensure that they were both in contact with a heat conductive medium. Aluminium conducts heat a million times better than air.

Aluminium (or aluminum; see spelling differences)

Hmm looks like an interesting product to try. I would be a little concerned that it is normally used to insulate pipes from a cold environment instead of being heat resistant. The concern being the product may melt when introduced to 110C, but it is worth trying out to see!
