fischer Insulation support metal DHM 210

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

Art.-No. 536259
Top Features
  • Simple Hammerset installation saves time and costs.

Product Description

The fischer metal insulation support DHM is simply hit in with a hammer. The hammer installation allows fast setting, thereby reducing the amount of work. Thanks to the fire resistance rating F 120 achieved, use is possible if there are fire resistance rating requirements. With the metal insulation support DHM you can, for example, fix mineral / glass wool, foam glass tiles and light building boards made of wood wool.
  • 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 for 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 extirior applications.
