DHK 40 - fischer fixings

fischer Insulation support DHK 40

The cost-effective plastic insulation support for all soft insulating boards.

Art.-No. 80937

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.

Product Description

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.

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.

Application and Permission

Applications

To fix soft and pressure-resistant insulating materials in rear-ventilated façades, such as:

Mineral / glass 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

You can find detailed information on building materials in the registration document.

Assembly Instruction

Functioning

The DHK is set in push-through installation using a hammer.
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.
