Mapei Mapetherm AR1 GG 25kg is ideal for bonding all types of thermal-insulating panels (foam/extruded polystyrene, foam polystyrene, mineral fibres, cork, wood fibres, etc.) directly on render, masonry and concrete on walls and ceilings.

Smoothing thermal-insulating panels with embedded fibreglass reinforcing mesh on internal and external walls (thermal insulation system).

Application examples

Bonding and smoothing internal and external heat-insulating panels and thermal insulation systems on:

• Cementitious render or lime-mortar render
• Concrete
• Concrete blocks
• Brick blocks

Also suitable for bonding and smoothing 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.

Technical Characteristics 

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.
• Coverage: 3.6m2 at a thickness of 5mm
