A free flowing thermal insulation which may be installed by auger feeding, blowing or pouring is disclosed. Granular material having a requisite K value (e.g., 0.20-0.315 BTU-in/.degree.F-ft.sup.2 -hr) is a major component of the insulation and is thoroughly mixed with a minor component of fibrous thermal insulating material to form a mixture which is used to provide the thermal insulation. Also included in the thermal insulation is a dust suppressant in quantities as required.
