Application areas

TECHNOSANDWICH BETON slabs are designed to be used as a heat- and sound-insulation layer in three-layer concrete and reinforced concrete wall panels.

TECHNOSANDWICH S slabs are designed to be used as a heat- and sound-insulation layer in three-layer wall sandwich panels with metal coverings.

TECHNOSANDWICH K slabs are designed to be used as a heat- and sound-insulation layer in three-layer roof sandwich panels with metal coverings.

Description of material

TECHNOSANDWICH are nonflammable, waterproofing, heat- and sound insulating slabs made of basalt rock stonewool with a low-phenol binder.

Storage

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.
