Vitcas' very own large, exfoliated, granular sized Vermiculite for use as a high temperature insulation in an enclosed space. This category also includes our exceptional vermiculite fire bricks.
Vermiculite granules are rated at 1100oC and they are characterised by their heat expansion properties, good insulation, low thermal conductivity and ability to store moisture. Vermiculite is available in a larger pack in loose form for a variety of applications such as insulating behind firebacks, insulation of pipes and acoustic insulation in walls, or as a smaller pack specifically for use in gas fires.
Vermiculite fire bricks
The vermiculite bricks withstand temperatures reaching 1000oC, do not conduct heat and are insulating. They are also very easy to saw, drill or sand.
