Application areas

TECHNOACOUSTIC slabs are recommended for application as a sound absorber in frame-wall partitions and facings, false ceilings, and floor structures with no-load installation of insulation material. The use of TECHNOACOUSTIC in the above-mentioned structures ensures their conformity to construction standards and regulations, requirements for fi re safety and environmental comfort.

Description of material

TECHNOACOUSTIC nonflammable, waterproofing, sound-insulating slabs made of basalt rock stonewool. The special arrangement of fi bers ensures high sound-absorption properties. Enhanced physical and mechanical parameters provide for the reliable use of the material in vertical structures for more than 50 years.


The slabs must be stored in covered warehouses. Storage under an awning protecting the slabs from atmospheric precipitation is permitted. slabs during storage should be laid in containers or in piles on pallets or linings. The piling height during storage should not exceed 2m.
