THERMAL INSULATION MATERIAL AND METHOD FOR PRODUCING THERMAL INSULATION MATERIAL
An object is to provide a thermal insulation material excellent in both thermal insulation property and mechanical strength. A thermal insulation material includes a thermal insulation layer containing silicon dioxide particles and inorganic fibers, and is excellent in both thermal insulation property and mechanical strength, because density ρ [g/cm3] of thermal insulation layer, and a cumulative proportion R1 for a fiber length of >0 mm and <4 mm regarding inorganic fibers contained in the thermal insulation layer and a cumulative proportion R2 for a fiber length of ≥3 mm and <30 mm regarding inorganic fibers contained in the thermal insulation layer satisfy a relational expression (I) below, R1 and R2 being calculated according to predetermined calculation formulae when the inorganic fibers contained in the thermal insulation layer are summed up based on predetermined conditions.0.23R1+0.24<ρ≤-0.11R2+0.53Relationalexpression(I)
