ISOMAT AK-T55 is used, in combination with MARMOCRET PLUS and MARMOCRYL plasters, as a system for external thermal insulation of structures.
It is suitable for glueing thermal insulation boards from extruded or expanded polystyrene, stone wool, polyurethane, cork, etc. on the exterior of buildings, on concrete, plaster or brick masonry surfaces.
In addition, reinforced with fiberglass, it is used to cover the thermal insulation boards and is thus the ideal substrate for the plaster that will follow.
