I guess there are a variety of refractory insulations on the market such as "VERMICULITE" and "PERLITE" I was just told that there is another called "SHERLITE or SHERLIGHT" (Sorry I'm not exactly sure how you spell it.) I was told that it's made especially for the construction of wood fire ovens and the likes as opposed to "VERMICULITE" and "PERLITE" which was originally used as a fertilizing agent often found in nursery's. Apparently this "SHERLITE" works just as well as the other two mentioned and it's just a matter of mixing it with water until it reaches a toothpaste consistency. The bonus with "SHERLITE" I have been told is that it's so much easier to work with as opposed to "VERMICULITE or PERLITE"

My query is has anyone heard of this stuff called "SHERLITE" or better still has any one used it?

P.s. Sorry about not knowing the correct spelling Re: "SHERLITE"

Hi Dmun

Regarding " We are warned off the silicone treated stuff used in domestic insulation, but that isn't that common" why is that?
I've found the attached which sells for about £10 forr 100 litres which is pretty good.

No, that's exactly the right stuff. The silica in the vermiculite is different from the waterproofed stuff that's sold for domestic insulation: It's treated to resist water absorption, which is how the vermculite turns into vermiculite concrete, by mixing portland and water with it.

Dean,
just be careful not be duped into buying an expensive alternative to vermiculite.
I was lead to believe that vermiculite was used not as a fertilizing agent in nurseries, but to bulk out the potting mix as well as retaining copious quantities of water for the plants.
Just make sure that the insulation is not as Davd says silicone treated.
