Abstract
The invention relates to stone wool formed from stone melt and consisting of 70 to 90% by weight stone wool fibers having diameters of up to 5 .mu.m, 0 to 5% by weight stone wool fibers having diameters above 5 .mu.m, and 10 to 25% by weight shot having a diameter of at least 63 .mu.m, and in which the average diameter of the fibers is from 1 to 4 .mu.m, the ratio of average fiber length:average diameter is 1,000 to 3,000, wherein the stone wool has a density from 12 to 85 kg/m.sup.3 and thermal conductivity lambda values from 30 to 40 mW/m.degree.K at 10.degree.
