Default Is this the right stuff?

I found a local supplier of vermiculite, and just wanted to make sure that this would be good for base and dome? and if so how much? seems kinda expensive ($25/18lbs)

heres the Material safety data sheet for it, it doesn't look like it contains silicone or other not so good stuff

That's about twice what I paid.

You may have better luck looking for a supply house for green houses. Pool builders may have some extra but it may have portland already mixed in with it.

Thats the stuff. I had a heck of a time finding a local source, let alone someone who knew what vermiculite even is! One gut told me he thought it was a sandwich topping. Uh yea right! U line shipped out four bags to me 4.0 cu. ft each. I think the cost total was $120. It arrived as promised in 2 days. Oh, BTW the grade 4 is fine

That's it. I used 4 bags in an 8" thick x 48" x 70" insulated slab

U line is definitely more expensive than some sources but they have it, are easily located, and the shipment is painless (other than money). When I built my insulated slab I spent several days searching locally to no avail and finally gave up and ordered from U-line. I think it is well worth checking with garden suppliers and such locally but...I certainly wouldn't spend days again!

Awesome, Thank you very much for all your reply's. I will be going probably tomorrow as there is one about 20min away from me, do you think the larger or smaller particles will work best. I was thinking the smaller

Thanks again

One thing to consider as I just re-read your first post. Vermiculite weighs very little. It's used as a shipping protectant and spill absorbent. A 4 cu ft bag only weighs about 7-8 lbs so you may want to see how much in volume your other source is for the 18 lbs. Just a thought.

I purchased my 4 CF bags from a local horticulture shop. I found the distributor for Perlite\Vermiculite in Michigan through the Perlite website and they directed me to the closest place near me. $25 a 4cf bag sounds crazy. I paid $7.

Give these guys a call and they should be able to direct you to a local source. They will probably have both Perlite\Vermiculite, but it does not matter what you use.
