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

Insulation support DHK / DHK 45

The fischer insulation support DHK is the economical plastic insulation support for soft insulation. The optimised geometry of the expansion section ensures a low anchorage depth and reduces the amount of drilling required. DHK is hammered in the push-through installation. When hammered, the ribs expand in the drill hole and the optimal pressure is applied to the DHK. Flexible pins in the plate area adapt to the insulating material, and ensure a sustained contact pressure. The fischer insulation support DHK 90 is suitable for anchoring insulation 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.
The flexible DHK plate adapt to the insulating material, and ensures 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.

Applications

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

Mineral 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
Solid sand-lime brick
Natural stone with dense structure
Aerated concrete
Solid brick made from lightweight concrete
Solid brick

Functionality

The DHK is set in push-through installation by using a hammer.
The plate size of the insulation support is to be selected in line with the compressive strength of the insulating material: DHK 45 for pressure-resistant; DHK for soft insulating materials.
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.
