      Top Features
      • Reduced drilling. Optimised geometry lowers anchorage depth.
      • Permanent pressure due to flexible pins in the disc area.
      • Simple Hammerset installation saves time and costs.
      • The colouring means that it does not stand out on black clad insulating material.

      The advantages / Product description

      The cost-effective plastic insulation support for all soft insulating boards.
      Advantages
      • The optimised geometry of the expansion section ensures a low anchorage depth and reduces the amount of drilling required.
      • Flexible pins in the plate area adapt to the insulating material, and ensure a sustained contact pressure.
      • The simple hammerset installation allows for a quick installation process and thus reduces workload.
      • The colouring of the DHK means that it does not stand out on black clad insulating material in rear-ventilated façades.
      The fischer insulation support DHK is the cost-effective plastic insulation support for insulating boards with low compressive strength. The DHK is knocked in the push-through installation using a hammer. When knocking in, the ribs expand in the drill hole and the DHK is ideally pressed in. The fischer insulation support DHK is suitable for anchoring insulating boards in solid and perforated brick, concrete, and aerated concrete.

      Application and approval

      Applications
      To fix soft and pressure-resistant insulating materials in rear-ventilated façades, such as:
      • Mineral wool
      • PU panels
      • Light building boards made of wood wool
      • Cork boards / coir matting
      • Polystyrene
      • Foam glass tiles
      Building materials
      • Concrete
      • Hollow blocks made from lightweight concrete
      • Vertically perforated brick
      • Perforated sand-lime brick
      • Solid sand-lime brick
      • Natural stone with dense structure
      • Aerated concrete
      • Solid brick made from lightweight concrete

      Assembly instruction

      Functionality
      • The DHK is set in push-through installation using a hammer.
      • The plate size of the insulation support is to be selected in line with the compressive strength of the insulating material: DHK 45 for pressure-resistant; DHK 90 for soft insulating materials.
      • The expansion of the ribs in the drill hole gives the DHK an ideal contact pressure.
      • Temperature range when installed: -40 °C to +80 °C.
