Mapetherm AR1 GG is a one component cementitious mortar for bonding, levelling and reinforcing
thermal-insulating panels and thermal insulation systems.
Mapetherm AR1 GG is suitable for the bonding of 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.
AR1 GG is also suitable for reinforcing coat for thermal-insulating panels with embedded fibreglass reinforcing mesh on internal and external walls (thermal insulation system).
Suitable applications include bonding and smoothing internal and external insulating panels and thermal insulation systems on:
- Cementitious render or lime-mortar render
- Concrete blocks
- Approved render boards
Also suitable for bonding insulation panels and reinforcing coat systems for:
- Insulating inside faces of walls in rooms above ground
- Insulating inside faces of retaining walls in basements
- Insulating inside faces of loft ceilings
- Insulating external faces of ventilated façades
- For use as a dash receiver and brick slip adhesive, plus synthetic brick slip or tile adhesive
Mapetherm AR1 GG is a grey or white powder made from cement, selected sand, synthetic resin and special additives with a fine grain size of up to 0.6 mm, developed according to a formula developed in MAPEI’s own research laboratories. When mixed with water, it forms a mortar with the following characteristics:
- Low viscosity and, therefore, good workability
- High thixotropic consistency: Mapetherm AR1 GG
- May be applied on vertical surfaces without running and without the risk of insulating panels slipping, including large sized panels
- Bonds perfectly to all materials normally used in the building industry
- Hardens without shrinking
