One-component, large-grained cementitious mortar for bonding and levelling insulation panels and for thermal insulation systems.

Where to use:

  • Bonding all types of thermal-insulating panels (foam/extruded polystyrene, expanded polystyrene, mineral fibres, cork, etc.) directly on render, masonry and concrete on walls and ceilings.

  • A reinforcing coat for thermal-insulating panels with embedded fibreglass reinforcing mesh on internal and external walls (thermal insulation system).


  • Do not use Mapetherm AR1 GG to bond insulating panels on metallic surfaces or substrates subject to large movements.

  • Do not use if the panels have a smooth surface, good bonding may be impeded: polyurethane or mineral fibres with a surface coating of kraft paper, extruded polystyrene with a surface skin, etc.


Packaging: Mapetherm AR1 GG is available in 25 kg paper sacks.
