I attended a masonry heater talk and got turned on to foamed glass in sheet form. The speaker was able to get 2' x 3' x 2" foamed glass to lay underneath his 3 ton masonry heater (in other words it has compressive strength). It has the appearance and feel of pumice. I had heard of foamed glass pellets in Europe that are kind of like perlite only not so crushable but never in sheet form. I called the insulation dealer up here in AK and they said it is special order but he hasn't got back to me yet on how much it costs. Anyone else hear or see or even have experience with this stuff?  |

When I lived in Seattle I used lava rock in my pond. Very light floated so well that I would put remote controlled motors in them, when the turtles would sun bathe on them I'd give them a ride. You can carve them with a butter knife, strong cheap good insulation.

Sorry for the late reply. I used to buy and use this for insulation in foundry work. You might try looking for it at places that either service the foundry industry, refractory dealers, or boiler servicing companies.

Thanks Machinemaker! I will keep looking. Did you use the foamed glass in sheet form? what sizes? What is your opinion of the stuff? |

I am in Japan. I saw some of this glass foam stuff last night put into sheet metal stoves designed for use with charcoal. It felt like styrofoam, I guess, but it must be robust stuff, of course. People are applying it to focus heat and protect pretty thin sheet steel, so it must be good. Of course, it is useful because it can be cut and formed. It bends too.
Don't know what temperatures it is good for, but people are using it.
