Vermiculite roof deck and insulating concrete
Vermiculite, soft mica like material, is crushed, cleaned, dried and sized, and resulting concentrate is exfoliated in furnaces at temperatures of 1800 to 2000 F; thermal conductivity ranges from 0.6 to 0.96 Btu/hr/sq ft depending on mix ratio; its common use is for light, structural roof decks, and for insulation fill; best mixture of vermiculite-concrete for roof construction is 1:4 and for roof insulation 1:6 and 1:8; methods of mixing and handling.
