Stand-off installation TherMax 12

The approved stand-off installation with thermal separation in external thermal insulation composite systems

The fischer stand-off installation system TherMax 12 is a solution for thermally separated fixation in external thermal insulation composite systems (ETICS) and non-load-bearing layers with a thickness of between 62 mm and 170 mm. In combination with the fischer injection mortars, the system is approved for fixations in concrete and masonry. The approval ensures added safety. The threaded rod has a glass-fibre-reinforced cone and cuts its own way through the plaster and into the insulation material without a setting tool. This saves time and money during the installation process. The fischer TherMax is steplessly adjustable when faced with uneven base materials. It is used to secure heavy loads like awnings, air conditioning units, and satellite antennas in concrete, aerated concrete, and masonry made from perforated and solid brick.

Product Description

  • When combined with the injection mortars FIS EM Plus, FIS V, FIS SB and FIS Green, the stand-off installation is approved for high loads in a range of materials. This allows for a secure fixing.
  • Usage lengths of 62 to 170 mm can be covered with just one TherMax.
  • The plastic cone creates a thermal barrier between the fixture and the inner fixture, and offers an energy-optimised fixing.
  • The glass-fibre-reinforced plastic cone cuts its own way through the ETICS with a positive fit, and allows for a simple, fast and adjustable installation without the need for any special tools.

Assembly Instruction

  • The TherMax 12 is suitable for pre-positioned installation.
  • The self-tapping, glass-fibre-reinforced cone cuts its own way through the plaster into the insulation during installation.
  • The anti-cold cone uses a thermal barrier to minimise heat losses.
  • In the case of resistant plaster (e.g. thick cement plaster), it is recommended that the TherMax cutting blade included is used for grinding out the plaster.
  • The sealing of the annular gap with the sealant adhesive KD or construction sealant Premium DKM seals the façade at plaster level.
