PROMAFOUR® CONSTRUCTION BOARDS

ADVANTAGES

  • Large-sized, self-supporting
  • High mechanical strength
  • Good thermal insulation
  • Good sound insulation properties
  • A1, non-combustible to DIN 4102
  • Ease to shape and work
  • Good chemical resistance
  • Hygroscopic and vapour-permeable
  • Unaffected by humidity
  • Retains shape stability and load capacity in humid conditions
  • Promafour

    PROMAFOUR® boards are cement bonded calcium silicate based insulation boards and are asbestos free. These large-sized multi-purpose boards are easy to handle and offer a superior combination of enhanced technical properties for building strong, mechanically self-supporting constructions.

    PROMAFOUR® boards are hygroscopic and vapor permeable. Moisture content is therefore automatically regulated by the application environment. Water vapor absorption can slightly affect the strength and thermal performance characteristics of these materials.

    Working & Processing
    < #Back#
    Woodworking machinery with hard metal-tipped tools can be used for producing and shaping cut sections.
    When shaping, the maximum allowable workplace concentration for inhalable dust generation must be observed.
    Dust extraction is recommended.
