Application areas

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

Description of material

TECHNOFAS slabs are designed for the use in civil and industrial construction as heat- and sound insulation in external insulation systems for walls with a protectivedecorative layer made of a thin plaster coat.


The slabs must be stored in covered warehouses, separated by brands and dimensions. 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.
