Capoto System (ETICS): what it is, how it works, and its advantages
Thermal insulation is an essential factor in modern construction, contributing to interior comfort, energy efficiency and the durability of buildings. Among the various solutions available, the Capoto System, also known as ETICS (External Thermal Insulation Composite System), stands out for its effectiveness and versatility.
Widely used in new construction and façade renovation, Capoto improves the thermal performance of buildings, reduces energy consumption and increases structural protection.
What is the Capoto system (ETICS)?
The Capoto System is a thermal insulation method applied to the exterior of a building’s walls. This system creates a protective barrier that prevents heat exchange between the interior and exterior, keeping internal temperatures more stable throughout the year.
The term ETICS refers precisely to this concept: a composite system that combines several materials with complementary functions, resulting in an efficient and durable solution.
Composition of the Capoto system
Capoto consists of different layers, each with a specific function:
- Insulating boards: usually made of expanded polystyrene (EPS), extruded polystyrene (XPS) or mineral wool, responsible for thermal insulation.
- Adhesive mortar: used to fix the boards to the supporting wall.
- Fibreglass mesh: reinforces the system, preventing cracks and ensuring stability.
- Coating mortar: applied over the mesh, acts as a protective and levelling layer.
- Final finish: may include fine plasters or decorative paints, offering additional protection and a customised aesthetic appearance.
How the Capoto System is applied
The application of Capoto follows several carefully executed stages:
- Surface preparation – cleaning and checking the adhesion of the base.
- Bonding of the insulating boards – uniform fixing to ensure continuity and eliminate thermal bridges.
- Mechanical fixing (optional) – use of specific plugs to reinforce adhesion.
- Application of the base layer and reinforcement mesh – creation of a stable and resistant surface.
- Coating and final finish – application of the decorative layer that protects the system and defines the final appearance of the façade.
The quality of the application is crucial to the performance of the system. It is essential to use skilled labour and certified materials. Incorrect installation can compromise durability and reduce thermal efficiency.
Advantages of the Capoto System
Energy efficiency
Capoto significantly reduces heat loss, improving the overall insulation of the building. This gain translates into less need for heating and cooling, resulting in energy savings and reduced consumption costs.
Thermal and acoustic comfort
In addition to thermal insulation, the system contributes to acoustic comfort, attenuating noise from outside and providing a more stable and pleasant indoor environment.
Protection and durability of façades
By protecting walls from temperature variations, humidity and leaks, Capoto extends the useful life of façades and prevents structural problems such as cracks or condensation.
Aesthetic enhancement
The system allows for a wide variety of finishes, colours and textures, offering creative freedom and enhancing the aesthetics of the building, both in new constructions and renovations.
Capoto and sustainability
The use of the Capoto system contributes to sustainable construction practices. By improving energy efficiency and reducing dependence on air conditioning systems, Capoto helps to reduce CO₂ emissions and the environmental impact of buildings.
In addition, many of its components are recyclable, reinforcing the commitment to long-term sustainability.
System maintenance and durability
When correctly applied, Capoto has a durability of over 25 years. However, it is important to carry out periodic inspections and minor maintenance, such as cleaning surfaces and repairing localised damage.
Preventive maintenance ensures thermal performance and aesthetic appearance for decades.
Capoto vs other types of insulation
Unlike systems applied from the inside, Capoto eliminates thermal bridges and maintains the thermal inertia of the walls, allowing for more uniform comfort.
Compared to blown insulation, the Capoto system offers greater protection against infiltration and degradation of the façade, making it a more complete and durable solution.
The Capoto system is an efficient, durable and sustainable solution for the thermal insulation of buildings.
To ensure optimal performance, it is essential to choose quality materials and rigorous technical execution. When correctly installed, Capoto improves comfort, reduces energy costs and increases the long-term value of the property.
At J.A. Duarte & Filho, the application of this type of system is part of our portfolio of construction and renovation work, integrating into projects that enhance the energy efficiency and structural performance of buildings.
