Application areas

TECHNOFLOOR GRUNT slabs are designed for heat- and sound insulation of floors on the ground, floating floors, and heated floors. TECHNOFLOOR STANDARD slabs are designed for heat- and sound insulation of floating floors when placing concrete or cement underlayment directly on heat insulation. TECHNOFLOOR PROF slabs are designed for heat- and sound insulation of floors with increased basic loads, including floating floors, heated floors, floors for underlayment of industrial, sports premises and warehouses.

Description of material

TECHNOFLOOR are nonflammable, waterproofing, heatand sound insulating slabs made of basalt rock stonewool with a low-phenol binder.


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 2 m.
