Saving energy and reducing the environmental footprint are priority objectives in any renovation or construction project. In this context, ETICS (External Thermal Insulation System) has become an increasingly used solution in new construction and renovations.
This system offers multiple benefits that improve interior comfort, enhance the property's value, and contribute to a sustainable construction model.
How does SATE improve thermal comfort?
Optimization of the building envelope
The application of ETICS thermal insulation reinforces the building's thermal envelope, significantly improving its energy efficiency. When installed on the exterior, it guarantees continuous insulation without reducing the interior living area and contributes to reducing CO₂ emissions.
Elimination of thermal bridges
One of the main positive effects of ETICS is the elimination of thermal bridges, points where heat is lost in winter or gained in summer. Proper installation improves the building's thermal inertia and reduces energy consumption.
Recommended materials and thicknesses
The materials used must have a European Technical Approval (ETA). The most common and effective are:
- Expanded polystyrene (EPS)
- Extruded polystyrene (XPS)
- Mineral wool
The thickness of the insulation will depend on the prior technical study, but usually ranges between 40 and 180 mm.
Energy and economic savings with SATE
Reduction of consumption in winter and summer
A well-installed EIFS system reduces heat loss in winter and limits overheating in summer, which can translate into energy savings of up to 60%. It also improves thermal transmittance, reducing it by up to 75% or more, depending on the materials and climatic conditions.
Return on investment
The amortization of SATE thermal insulation typically occurs between 5 and 7 years, although the savings in heating and cooling are noticeable from the outset.
Real cases and efficiency data
In places like Mallorca, Madrid, and Bilbao, improvements have been recorded, such as:
- Reduction of 30% in total energy consumption.
- Savings of 50% on heating gas.
- Thermal transmittance reduction from 79% to 85%.
Key factors for achieving maximum effectiveness
Professional installation
It is essential that the EIFS system be installed by qualified professionals, as improper installation can compromise its performance and durability.
Choosing insulation and finish
Each type of insulation offers different characteristics:
- EPS: efficient and economical, ideal for moderate climates.
- XPS: greater resistance to moisture and impact, ideal for extreme climates.
- Mineral wool: excellent acoustic and fire performance.
The exterior finish not only improves aesthetics, but also the adhesion and resistance of the system.
Adaptation to climate and orientation
The choice of insulation and its thickness should be tailored to the local climate and the facade's orientation. For example, on south-facing facades, materials that reduce overheating are sought, while on north-facing facades, heat conservation is a priority.
Comparison with other insulation systems
SATE vs. ventilated façade
- The SATE offers better thermal performance compared to the ventilated chamber.
- Lower installation and maintenance costs.
- Greater temperature conservation capacity.
- Estimated lifespan: up to 50 years.
SATE vs. sprayed mortar
- Mortar pays for itself sooner, but has a shorter lifespan (approximately 10 years).
- The SATE increases the property's value and offers better thermal and acoustic insulation.
SATE vs. injected foam or other systems
- Injected foam does not guarantee uniform coverage.
- Greater need for maintenance.
- They do not effectively prevent thermal bridges or control humidity like SATE.
Is SATE suitable for luxury villas?
High-end aesthetics and finishes
The ETICS allows for the application of a wide variety of customized finishes, with textures, colors, and materials that integrate perfectly into luxury homes. It provides elegance, aesthetic coherence, and added value.
Sustainable certifications
This system facilitates obtaining certifications such as Passive House or LEED, which increases the property's market appeal and reflects a commitment to sustainability.
Impact on property value
Numerous studies show that ETICS thermal insulation increases property value, improves efficiency, and reduces the time on the market when sold. It is, without a doubt, a smart investment for high-end villas.
