It is a natural mineral composed of inorganic components. Since 1940, it has been used intensively in industry for various uses. Expanded vermiculite due to its excellent insulating capabilities and its natural high temperature properties is the most suitable material for insulation in the combustion space of the energy fireplaces.
Its main characteristics are its low weight, its variety in shapes, thickness and density, its easy use, its durability, its perfect thermal insulation.
The main technical characteristics of vermiculite:
1) It can withstand temperatures up to 1150 ° C
2) During combustion it develops temperatures up to 650 ° C which cannot have other materials respectively (cast iron or firebrick).
3) Vermiculite hearths, because of the high temperature they raise (from 450 ° to 650 °), work as catalyst, due to the increase in the temperature of post-combustion of CO monoxides by converting them to CO2 dioxide. Thus, we achieve very low CO oxides in the combustion of <0.02% to 13% O2, a performance that is among the top in the category of energy hearths.
4) Maintains its natural beige color without being tainted by combustion of the fireplace, as it does pyrolysis itself.
5) It does not contain ceramic fibers or asbestos, it is non-irritating and odorless and therefore completely safe, both for the health of the consumer and for the personnel handling it.
