Modular homes with SATE facade: everything you need to know

Modular homes have revolutionized the construction industry thanks to their efficiency, speed, and precision. But when these advantages are combined with an exterior insulation system like ETICS, the result is an even more sustainable, comfortable, and durable home. In this article, we explain in depth why the combination of modularity and SATE façade It is one of the smartest options you can choose if you are thinking about building your home.

What is the SATE system and why is it gaining so much popularity?

The SATE, or Exterior Thermal Insulation System, is a technique that involves applying insulating panels to the exterior of a home's walls, then covering them with a protective coating. Unlike other systems that insulate from the interior or core of the wall, ETICS acts as a continuous envelope that protects the entire living space from the outside. This thermal barrier reduces heat loss in winter and prevents outside heat from penetrating in summer, resulting in a more comfortable home with much lower energy consumption.

This type of system not only significantly improves energy efficiency but also protects the building's structure from humidity, wind, and sudden temperature changes. It's no coincidence that many homes aspiring to achieve high levels of sustainability choose ETICS as a key solution for their thermal envelopes.

Modular homes and SATE systems: a combination of precision and efficiency

One of the great benefits of modular homes is that they are manufactured in a controlled environment, where every detail is calculated and executed with millimeter precision. This methodology fits perfectly with the EIFS system, as it allows the insulation panels and cladding to be applied without weather interference or unforeseen construction issues.

The result is a cleaner, faster, and more durable installation. In the modular context, the ETICS is not an added improvement after construction, but is integrated as part of the design from the outset. This achieves a uniform, well-sealed finish that meets all technical and aesthetic requirements, without increasing construction times.

What are the real advantages of SATE in prefabricated homes?

Using EIFS in a modular home is not only a technical issue, but also a strategic decision for those seeking a better life. An EIFS façade improves the home's overall energy efficiency and contributes to a more stable interior temperature, reducing dependence on air conditioning systems and, consequently, reducing monthly utility costs.

Furthermore, this system provides a significant aesthetic improvement, as it allows for a variety of finishes and colors. The home gains in design without sacrificing insulation. In terms of maintenance, it also performs better than other conventional cladding systems, as the system itself protects the structure from wear and moisture.

What differentiates SATE from other insulation systems?

The main difference between ETICS and other methods lies in its location: while traditional systems typically insulate from the inside, ETICS insulate from the outside. This has very specific advantages. For example, by installing insulation on the exterior, thermal bridges—those small cracks through which heat escapes—are eliminated, usable space is gained inside the home, and the structure is better protected from environmental damage.

Other systems, such as interior insulation with cladding, may be more economical in the short term, but they don't offer the same thermal performance or long-term durability. In a modular home, where everything is designed to optimize resources and minimize errors, ETICS is a perfect fit.

What materials are used to apply SATE to modular homes?

EIFS (Electronically Insulated Building Materials) have evolved significantly in recent years, adapting to different thermal, acoustic, and aesthetic needs. Among the most commonly used are EPS (expanded polystyrene), ideal for its lightness and good value, and XPS (extruded polystyrene), which stands out for its greater resistance to moisture.

Mineral wool, which offers excellent fire resistance and excellent sound insulation, and more environmentally friendly alternatives such as natural cork are also used. All of these materials are covered with a protective layer of mortar and a reinforcing mesh, which can be finished with paint, plaster, or even ceramic finishes.

What technical requirements must be taken into account?

Installing an ETICS in a modular home requires a perfectly level and prepared surface, something that's easy when factory-made. It's essential to choose the right type of insulation based on the climate zone, the home's orientation, and the type of use it will be used for.

Furthermore, rigorous technical criteria must be followed regarding mechanical or adhesive fixation, the treatment of corners and gaps, and the choice of final cladding. When all of this is considered from the initial module design, the system is not only more effective but also more durable.

Does the SATE system have any disadvantages?

Like any construction system, ETICS is not perfect. Although its benefits far outweigh its limitations, it is important to know that its installation requires a certain degree of technical expertise. It is not simply a matter of "gluing panels together," but rather the application of a complete system with successive layers that must be executed with precision.

Furthermore, the initial cost may be slightly higher than other methods, although it quickly pays for itself thanks to energy savings. And while maintenance is simple, in the event of damage or impacts to the façade, repairs should be carried out with compatible products to avoid affecting the overall performance.

How is a SATE façade maintained?

Maintenance of ETICS is minimal, but not nonexistent. Facades should be inspected periodically to detect possible cracks or wear. They should also be cleaned periodically, especially in areas highly exposed to pollution or rain. Many coatings include anti-fungal and self-cleaning treatments that further extend their useful life.

With proper maintenance, an ETICS façade can maintain its thermal and aesthetic properties for more than 25 years, making it a long-term solution.

How much does it cost to apply SATE to a modular home?

The price of an SATE façade can vary depending on the type of insulation, the thickness required, and the finishes chosen. In general, the cost usually ranges from 60 and 100 €/m², including materials and labor. In the case of modular homes, since they are factory-assembled, this process is much more efficient, allowing for cost optimization without compromising quality.

When you calculate the return on investment in terms of energy savings, ETICS is one of the most cost-effective solutions you can choose for your home.

What does the ETICS contribute to the energy efficiency of modern homes?

Energy efficiency isn't a fad: it's a necessity. ETICS directly contribute to a modular home achieving high levels of sustainability and comfort. It not only improves the home's thermal performance but also helps maintain a more stable temperature throughout the year, reducing the need for heating or air conditioning.

Many modular buildings using the EIFS system have achieved low-consumption certifications such as Passivhaus or energy class A+, demonstrating that this solution is not only efficient but also reliable and perfectly applicable in real-life settings.

In summary

The combination of modular house and SATE façade It represents a winning alliance between technology, sustainability, and comfort. If you're thinking of building your next home with superior quality standards, lower consumption, and greater durability, this option should be at the top of your list.
