U.S.Buresu of Standards INSULATING PLASTER Perhaps the most quickly evident saving in installation time because of the light-weight characteristics of vermiculite is where the material is used in the making of a fire-proof, insulating plaster. Plaster aggregate made from vermiculite replaces sand, and is mixed with gypsum and troweled on in the same fashion as sand plaster. In many communities, vermiculite has completely replaced sand and is adopted as standard. Vermiculite plaster offers a definite superiority over sand in its sounddeadening and fireproofing qualities. Weight-saving is especially notable where vermiculite plaster is used to provide fire-proofing of beams, columns, floors, and ceilings. Table 1 shows the resume of fire tests which have been conducted utilizing vermiculite for this purpose. INSULATING CONCRETE metal lath. 2h" “sand concrete fill §" vermiculite plaster on metal lath.
