extension using a material which meets the
followingspecications:alayerofnoncom-
bustible, inorganic material having a thermal
conductivityofK=0.84BTUIN/FT,HR.F(or
less)at1"thick.Forexample,ifthematerial
selected has a K factor of 0.25, such as glass
ber,thefollowingformulawouldapply:
0.25 x 1.0" = 0.30" thickness required
0.84
Thermalconductivity"K"ofmaterialscanbe
obtained from the manufacturer or supplier of
