Isomat AK-T55 is a fiber reinforced, cementitious adhesive, reinforced with polymer components. 

Isomat AK-T55 provides high initial and final welding strength, elasticity and moisture resistance. It is used, in combination with plaster, as a system for the external thermal insulation of structures. It is suitable for gluing thermal insulation boards of polystyrene, stone wool, polyurethane, cork, etc. on the exterior of buildings, on concrete surfaces, plaster or masonry with bricks. In addition, it is applied to the coating of thermal insulation boards and is thus the ideal substrate for the plaster that will follow.
