Looking for source for vermiculite for a lighter RMH...

Would like to experiment with putting a RMH in a double wide. I am wanting to try using Vermiculite to cut down on weight. Any ideas where you can get that much without spending much? Thanks for ideas in advance. 

Also looking for stories from those that made RMH's that don't look like a big dried mud bench in the living room. I am thinking that a nice wood bench could be built around the mass, no? Anybody tried? Thanks, John

should be able to get it from a garden store or landscaping outfit
maybe as waste from a someones remodel if you dont mind burning off the paper backin

don't know how well it will work but if you build it make sure you let us know

My local hardware store ordered a couple of bags for me.  If you talk to a sales clerk, they may just say they don't have it.  Try to talk to the boss.

Having said that, the M in RMH is mass.  That's basically the same as weight.  Adding anything that will lighten the bulk will turn it from a heat storage unit into an isulating one and your heat will go up the chiney.

I went to garden centers, hardware stores, etc, nada.  Then I happened to ask at the local Feed & Grain: yep.

I'd say the feed store. I get 4 cu. ft. for $12.

doesn't vermeculite contain asbestos?

Vermiculite is a heat-expanded mica.
