      The fire-protection-tested metal insulation support for fire-resistant insulating boards.

      Insulation support DHM

      The fischer insulation support DHM is a fire-tested metal insulation support for pressure-resistant insulation boards. The fire resistance rating F 120 guarantees a secure fixing of fire-resistant insulation. The DHM is hammered in the pre-positioned installation. The simple hammer installation allows fast setting, thereby reducing the amount of work. The spring steel expands in the building material and holds the insulation boards securely in concrete, aerated concrete, solid and hollow building materials. The DHM is hammered into aerated concrete without pre-drilling. This saves time.

      The advantages / Product description

      Advantages
      • The metal insulation support achieves fire resistance F 120. This means that it can be used where there are fire resistance requirements.
      • The DTM 80 plate for soft insulating materials (available separately) simplifies storage and minimises costs.
      • The simple hammerset installation allows a quick installation process and thus reduces workload.
      • The shaft geometry allows setting in aerated concrete without pre-drilling, thus saving a stage of installation.
      • Stainless steel version DHM A2 (1.4301) for wet and exterior applications.
      • The DHM can be combined with coloured cover caps, which complete the design of the surface.

      Assembly instruction

      Functionality
      • The insulation support is set in push-through installation by using a hammer.
      • When hammered in, the expansion part tightens like a spring with the substrate.
      • Use the DTM 80 plate (available separately) to fix soft insulating materials.
      • Optionally, the DHM can be set with a hammer drill and the EMS M6 setting tool
