Answer
Vermiculite granules are a natural material. the mineral mica is heated until it swells-up, similar to breakfast cerials. totally inert fire proof unlike polystyrene, cannot give off fumes.i would say by all means use it, its good insulation. bear in mind that no insulation provides heat, and heat loss through glass is extensive, so you may have to provide a source of heat.
