FIELD: technological processes.
SUBSTANCE: invention is related to production of mineral wool products, namely to methods for production of multi-layer mineral wool boards. Method includes compaction of primary mineral wool carpet, its horizontal longitudinal cutting into layers by thickness of the first cut layers of primary carpet, which is equal to thickness of the first board layer, the second layer of primary carpet is additionally compacted to density of the second board layer, shaping of double-layer carpet, supply of binding agent, thermal treatment. Thickness of the second layer of the primary carpet is arranged as equal to 
where h3 is thickness of the second layer of board, ρ1 is density of the first board layer, ρ3 is density of the second board layer.
EFFECT: increased quality of mineral wool boards.
