The weight percentage of mineral wool that can be cooled in the physical-physical medium of the present invention is as follows: (CaO + MgO + BaO + Na2O + K2O + B2O3) - 2 x Al2O3 30% RO 13.5 -0.9.5% R2O N 14.2 -23% RO / R2O 0,70 - 0,95 CaO / MgO N 1,5 SiO2 47 -58,5% Al2O3 N 0 - 3,5% B2O3 5 -10% Fe2O3 (total iron content) 0 - 3% of which RO is an anxiety of the periodic retention element IIA of the periodic system, including calcite oxide, magnesia-oxide, barium-oxide and ostrich-nocturnal, R2O is an elementary oxide of the periodic system, including the sodium oxide of sodium. , potassium oxide and lithium oxide. The invention is further contemplated for thermal and / or sound insulating products for heat-refining materials of ground-free excrements containing at least part of the mineral wool. ŕ
