Render fixing FIF-CS 8

The economic screw fixing for all ETICS insulation materials

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.

Product Description


  • 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.
