Applications in ETICS Systems

• Used for fixing EPS boards (white and graphite) and for creating the reinforced layer
• Used for fixing mineral wool boards (façade and lamella) and for creating the reinforced layer
• Recommended as a reinforced layer for render coats in dark or intense colours
• Recommended for façades where mineral wool and EPS need to be combined, especially for fire protection
• Suitable for insulating standard, passive and energy-efficient buildings
• Suitable for new buildings and for thermal modernisation projects
