Etics

ETICS stands for External Thermal Insulation Composite System, a method of exterior wall insulation in which insulation boards are fixed to the outer facade, covered with a base coat containing reinforcing mesh, and finished with a protective topcoat. It is used to improve the thermal performance of buildings, reduce energy consumption, and modernize façades. ETICS are widely applied in Europe and other regions as part of retrofit and new construction.

Typical components include insulation material such as expanded polystyrene (EPS), extruded polystyrene (XPS), or mineral wool; an adhesive or mechanical fixings to attach the boards; a base coat that embeds a reinforcing mesh; the reinforcing mesh itself; and a finishing coat that provides texture and weather resistance. Depending on the substrate and climate, additional elements such as damp-proofing layers or vapor barriers may be incorporated.

Benefits of ETICS include improved thermal efficiency, reduced heat loss, enhanced occupant comfort, and potential improvements in façade appearance and durability. It is used on a range of building types, from residential to commercial, and can be employed in both new construction and retrofits. The system can also contribute to acoustic insulation and moisture management when properly designed.

Installation and maintenance requirements are substantial: skilled installers are needed, and careful detailing is required at corners, openings, and penetrations. The system must be designed for weather, wind, and seismic loads, and substrates must be prepared correctly. Longevity depends on materials, workmanship, and ongoing maintenance.

Fire performance and standards vary by material and region. Mineral wool-based ETICS generally offer better fire resistance, while polystyrene-based systems require appropriate finishing and compliance with local regulations. Standards often address adhesion, detailing, and quality control to ensure system integrity.
