The economic screw fixing for all thermal insulation boards in an external ETIC-system.

Art.-No. 534159
Top Features
  • High load absorption due to innovative compoundscrew.
  • Low setting depth for all building material categories reduces amount of drilling. This saves time and costs.
  • No marks on the plaster surface. Glass fibre reinforced compoundscrew with steel point reduces heat transmission.

Product Description

The ETA approved fischer render fixing FIF-CS is ideal for fixing pressure-resistant insulation up to 340 mm thick for thermal insulation systems such as polystyrene boards or mineral wool boards in concrete, solid and perforated brick, lightweight aggregate concrete and aerated concrete securely . The uniform setting depth for all building materials simplifies installation. The screw fixing comprises a grey plug sleeve with attached octogonal disc and a compound screw. The compound screw minimises the thermal bridge. This in turn prevents plug marks on the façade. The FIF-CS 8 is set with a standard screwdriver.
  • Compound screw minimises the thermal bridge, thus there are no fixing marks on the façade.
  • Less drill wear and drill time due to minimum installation depth of 35 mm in the substrate.
  • With flush installation, the disc tapers to a very thin edge, thus providing for optimal retaining of the insulation panel and for application of thin  render.
  • For insulation material thicknesses up to 340 mm.
  • Standard embedment depth for all building materials.
