fischer Insulation support metal DHM 70 A2 stainless steel

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

Art.-No. 536264
Top Features
  • Simple Hammerset installation saves time and costs.
  • Stainless steel version A2 for use in wet and outdoor areas.

Product Description

The fischer metal insulation support DHM A2 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. The stainless steel version DHM A2 is suitable for use in wet conditions and outside. With the insulation support 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.
