Thermal insulation and fire protection for a cellar flooring with mineral wool-based plaster
Insulation of a cellar flooring with mineral fibre-based plaster bond with class A construction material.
The material consists of slag wool, and cement and other fire-prevention mineral additives as binding agents. This material is proven to be free of asbestos.
Area of activity:
CAFCO Heat-Shield® or Dossolan-Thermique® are used as thermal insulation, fire prevention protection, acoustic insulation for floorings of cellars, multi-storey car parks, as well as on concrete surfaces, steel supports, or steel girders, and other concrete surfaces.
Materials are processed with a spray-on method, and in accordance with manufacturer’s guidelines. Depending on a substrate, verified latex-based bonding layers or expanded metal mesh are installed. Machine techniques recommended by the manufacturer are used for injections.
The binding time is 8 to 10 days, depending on the air temperature. The final durability is achieved in about 28 days.
After processing, the surface is rough. On a Client’s request, the surface can be finished by rolling or pressing. To increase its durability, the surface will be coated with fibre hardener or paint.
