Combination modules

High temperature insulation wool


Combination modules without the addition of foreign substances were developed by RATH and, thanks to the RATH-specific connection system, represent a unique form of modular lining in the range of 1200°C – 1400°C.


Combination modules consist of two different mat types, such as Altra®–Alsitra® or Altra®–Calsitra®. This allows a very specific temperature range to be covered, in combination with pure Altra, Alsitra, or Calsitra modules, providing an optimal and very efficient lining.

Thanks to the RATH-specific connection system, which does not require addition of any foreign substances, combination modules also offer unlimited thermal shock resistance.
