Insulation support DHM

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

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.

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 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.
