Vermiculite Concrete Introduction Vermiculite concrete is a low density non-structural construction product It is insulating (both thermally and acoustically) and intrinsically fire resistant It is normally made simply by mixing exfoliated vermiculite as the aggregate, with cement and water, plus additives such as plasticisers if required
Exfoliated vermiculite is very efficient at retaining moisture, and in the event of a fire this turns to steam which has a cooling effect on the steel substrate and thus delays its temperature rise Vermiculite concentrate is also used in the production of fire resistant gypsum plasterboard (drywall or wallboard)

R-Values of Materials: Table of Insulation R-Values and ,
R-Value is expressed as rate of heat loss per hour per square foot per inch of thickness of material per deg F - see "R" value definition at Definitions of R K U values For some building materials (such as sheet flooring) we give an R-value for a specfic thickness other than the standard 1"
Oct 19, 2015· Definition of R-value Recommended levels of insulation Building codes specify a minimum level of insulation The optimum amount of insulation depends on guessing what the cost and availability of heating fuel (or electricity for cooling) will be over the life of the house, and comparing that with the cost of insulation
