Door Ballast

[Poops]

Hi All

My oven is more or less finished and is firing nicely, so time to think about building a door. I will probably will go with vermicultie sandwiched between sheets of aluminium or similar.
I've read a few different posts where people refer to various types of "ballast" that they are using in their doors - rivits, washers and the like.

Can someone explain the purpose - is it as simple is giving the door some weight so it stands upright?

Thanks All.

I made my insulated door exactly as you describe, minus any form of ballast. I dont see the need, its 2 1/2" thick and stands on its own. Maybe it is the 1" aluminum framework I built under the outer aluminum skin that gives mine a bit more weight and makes it less tippy.

Where did you purchase your firebrick?

Thanks.
