In the context of rising energy costs and increasing environmental awareness, renovating buildings for energy efficiency is becoming increasingly important. External thermal insulation composite systems (ETICS) are a proven approach to reducing the energy consumption of a building. Lower energy consumption reduces heating and cooling costs and reduces CO2 emissions.
A comprehensively insulated facade addresses heat leakage both at the surface and at thermal bridging points.
The increase in the surface temperature of the interior walls and the resulting minimisation of the temperature difference in the building contribute to a pleasant and even indoor climate and reduce the risk of condensation on the interior walls.
The external thermal insulation system consists of various layers of coordinated building materials. By selecting the right composition of the insulation system for the external facade of the building, heat loss is minimised.
The right choice of materials is crucial to ensure the long-term benefits of the system. ETICS is an investment that pays off for building owners in the long term and also contributes to environmental protection.
ETICS forms the building envelope. It provides protection from weathering such as rain and wind, thermal stress, UV radiation and other environmental factors. With the right composition, a mechanically durable facade can be created that extends the life of the building and minimises the need for maintenance.
The insulation system offers various design options that allow the facade to be adapted to the building owner's individual wishes. This can be an attractive option for building owners who want to invest in building renovation, take advantage of government subsidy programs and at the same time increase the attractiveness of a rental property.
High-quality insulation materials such as expanded polystyrene (EPS), extruded polystyrene (XPS) or mineral wool (MW) offer efficient insulation and low thermal conductivity. The correct choice of materials is crucial for the efficiency and durability of ETICS. Mineral wool itself can play a role in environmental sustainability as an environmentally friendly and sustainable material. In the plinth area and areas in contact with soil, materials such as XPS (extruded polystyrene) are the right choice. Moisture-resistant or diffusion-permeable materials are then essential to prevent damage and mould growth.
Strict fire regulations also apply to all types of buildings when it comes to insulation materials, ensuring the safety of the building and its occupants. Here, the type and height of the building, its use and other operational factors play a role.
All Cemixtherm insulation systems are designed to be easy to work with and allow for trouble-free installation. However, careful planning and professional workmanship is required to properly install ETICS.
Substrate preparation: The surface of the facade is cleaned and smoothed. A primer is applied to ensure optimum adhesion of the insulation materials. Damage is repaired to create a load-bearing substrate.
An adhesive and levelling compound is applied to the back of the insulator at 2-3 points and around the edges. In addition, the insulator is mechanically fixed with six dowels per square metre.
Cemix also offers adhesive filler for dowel-free installation. After protruding edges of the insulation boards have been ground flat, profiles are applied, drip edges installed and roof connections fitted.
Reinforcing fabric is incorporated into the applied adhesive filler to stabilize the system during thermal expansion and prevent cracking.
Depending on the insulation material used, different plasters and plaster thicknesses are used. Finally, the finishing plaster is applied to achieve the desired appearance of the facade. Colored pasteuse plasters save on the paint coat here.
The color choice of the facade is essential for the thermal expansion of your facade.
The finishing work includes sealing connections and joints on windows and doors, as well as on the roof.
