How aerothermal energy, solar panels and home automation allow you to reduce energy consumption and enjoy more sustainable and efficient homes.

Comfort inside a home does not depend only on the design or its facilities. A key aspect —and often underestimated— is thermal and acoustic insulation. A well-insulated home is not only more energy efficient, but also offers greater well-being, privacy and quality of life.

Below, we tell you about the main insulation materials and systems used today, their advantages and in which cases it is appropriate to use them.

At FILA we have been working for decades on construction solutions that improve energy efficiency, both in traditional construction and in industrialized housing. This experience has allowed us to verify which materials work best for each situation.

1. Aerothermal: efficiency with air energy

Aerothermal energy is one of the most efficient systems for air conditioning a home. It works by extracting the energy contained in the outside air —even at low temperatures— to transform it into heating, cooling or domestic hot water.

Advantages of aerothermal energy:

• Energy savings of up to 70% compared to traditional systems.
• A single machine for heating, cooling and DHW.
• Very low CO₂ emissions.
• High durability and less maintenance.
• Ideal for well-insulated homes, such as industrial ones.
• For new projects or deep renovations, aerothermal has become one of the most recommended solutions thanks to its reliability and efficiency.
• Roofs and facade envelopes.

2. Solar panels: renewable energy and self-consumption

Photovoltaic solar panels allow you to generate your own electricity by taking advantage of the sun's radiation. It is one of the most widespread systems in efficient homes.

Benefits of solar panels:

• They reduce the electricity bill by up to 60–90%.
• Possibility of dumping surplus into the network and obtaining compensation.
• Clean, silent and low-maintenance system.
• Useful life of more than 25 years.
• Perfect complement for aerothermal or electric vehicle chargers.

In industrialized construction, the integration of solar panels is especially simple: it is designed from the beginning and executed with precision in the factory and on site.

3. Heat recovery systems

Mechanical ventilation with heat recovery (VMC) allows the renewal of indoor air without wasting energy. It extracts stale air from the home and uses its temperature to heat or cool the incoming air.

Why it is so efficient:

• Reduces heating and cooling consumption.
• Guarantees healthier indoor air.
• Eliminates humidity, CO₂ and particles.
• Improves comfort in airtight homes.

This system is especially useful in modern homes with high levels of insulation.

4. Home automation and intelligent consumption management

Home automation allows you to control and monitor energy consumption in real time.

Common applications:

• Automatic regulation of heating and air conditioning.
• Management of lights according to presence or natural light.
• Control of solar self-consumption.
• Optimization of the operation of aerothermal systems.
• Precise measurement of consumption by zones or equipment.

A connected home helps avoid unnecessary consumption and improves daily comfort.

5. Underfloor heating

Underfloor heating is an efficient solution that works at low temperatures, making it the ideal companion for aerothermal heating.

Key advantages:

• Greater thermal comfort and uniform heat distribution.
• Significant energy savings.
• Compatible with cooling in summer.
• Invisible and without radiators.

Which system is the most recommended?

It depends on the type of home, the climate and usage habits. But in many cases, the most efficient combination is a mix of all possible options:

Aerothermal + Radiant floor + Solar panels + Home automation

A set that allows you to drastically reduce consumption, increase comfort and move towards a self-sufficient home.
At FILA, from our commitment to industrialized construction, we integrate these technologies from the design phase: this reduces errors, optimizes installation and guarantees maximum system performance.

Discover how construction with wood, previously associated with houses in the Pyrenees, is becoming consolidated in Catalonia and other regions as a sustainable, efficient and versatile option for modern housing.

Wooden houses are no longer an exclusive image of alpine refuges or second homes in the high mountains. Many people associate them with areas such as Cerdanya or the Pyrenees, but the reality is that this type of construction is expanding throughout the country and, particularly, in projects in Catalonia that combine sustainability, design and energy efficiency.

Wood is experiencing an unstoppable boom thanks to its thermal behavior, its low environmental footprint and its excellent fit with new industrialized construction systems.

Why do we associate wooden houses with the Pyrenees?

Historically, wood was the most accessible resource in forested and cold areas. For this reason, many of the first wooden houses in Cerdanya emerged as a logical solution to a demanding climate. But this perception has fallen short.
Today we are talking about a material capable of shaping modern, urban homes, with minimalist lines and highly efficient, not only in the mountains. CLT panels, lightweight frames and industrialized design allow us to build with precision and with technical guarantees superior to those of decades ago.

Wood and energy efficiency

Wood offers extraordinary natural insulation. It helps keep homes cool in summer and warm in winter, reducing energy consumption. That's why wooden houses not only work well in cold environments: they are also an ideal option in temperate and Mediterranean climates.

Advantages that explain its rise in Catalonia

• Renewable material with a low carbon footprint.
• Speed ​​of execution thanks to dry and industrialized construction.
• Natural humidity regulation and excellent acoustic and thermal comfort.
• Aesthetic flexibility: from rustic style to contemporary architecture.

At FILA, with more than 75 years of experience in construction and a firm commitment to industrialization, we see increasing interest in wooden houses in Catalonia, both for first homes and for tourist or multi-family projects.

Only for high mountains? Not at all.

Wooden houses are perfectly viable on the coast, in the city or in the interior. With the appropriate treatment against humidity and fire, an efficient design and a professional execution, they become durable and healthy homes.

Although regions such as Cerdanya and the Pyrenees have been pioneers in their adoption, the trend is spreading to the rest of the territory thanks to the need for sustainable and quick-to-build homes.

Looking to the future

Wood is destined to be one of the pillars of the building of the future. With hybrid systems, CLT panels and industrialized processes, building complete homes is becoming more agile, precise and responsible.
The question is no longer whether wood is valid outside the Pyrenees, but how long it will take for it to become the most common option in sustainable new construction.

Would you like to know if a wooden house is for you?

At FILA we can help evaluate systems, insulation and finishes to develop an efficient, healthy project with a lower environmental impact.

Contact our team and let's study your wooden house together, whether in Cerdanya in Catalonia or wherever you imagine your future home.

Below we offer a practical guide to analyze which decision best fits your needs (whether to renovate a home or build a new one), budget and objectives, with a focus on industrialized construction.

When someone considers having a custom-built home, the same big question often arises: Is it better to buy an existing house and renovate it, or build a new one from scratch? The answer isn't universal—each case involves technical, economic, and personal factors—but there are criteria that can help you assess which option might offer the best results based on your expectations.

Home renovation: advantages and limitations

Before you start your search, you have a clear idea of ​​what you want to build, your approximate budget, your desired timeframe, and your priorities (design, energy efficiency, specific materials, etc.). The more detailed your vision, the better you can communicate your expectations and assess whether a construction company can meet them.

Advantages of renovating a home

• A good option if location is key (urban centers, established neighborhoods).
• Allows for the preservation of original or historically significant features.
• Lower initial investment in some cases.
• Shorter completion times when the structure is in good condition.
• Potential for increased property value after renovation.

Drawbacks to consider

• Structural and design limitations: it's not always possible to do everything you want.
• Risk of unforeseen problems on site (concealed installations, structural defects, dampness, etc.).
• It's difficult to achieve energy efficiency levels comparable to new construction.
• It can end up costing more if it requires extensive work.

Renovating is recommended when the property has potential, the surrounding area is highly valued, and the project doesn't require drastic structural changes.

At FILA, we always analyze the initial condition to assess whether renovation is viable and profitable, providing a clear technical proposal and a transparent budget.

Building a new house: total freedom to design your home and efficiency from the start

Building from scratch offers the opportunity to create a home tailored to each family's lifestyle, with optimized orientation, layout, efficiency, and materials from the outset.

If industrialized construction is chosen, the advantages increase considerably thanks to technical control and factory precision.

Advantages of building new industrialized construction with FILA

• Custom-designed homes, not adapted to existing structures.
• Sustainable materials such as structural timber and eco-friendly insulation.
• Faster and more controlled construction times compared to traditional methods.
• Factory manufacturing reduces errors, waste, and accidents.
• Cleaner and safer on-site assembly.
• Greater energy efficiency and lower long-term maintenance costs.
• Adaptable to any terrain or environment—not the other way around—(slope, climate, regulations, etc.).

Industrialized construction is not a low-cost system. The investment is similar to or slightly higher than traditional construction, but the quality, durability, efficiency, and overall comfort are significantly greater. It's not about paying less; it's about paying better for a superior result.

Possible disadvantages

• Requires a building plot.
• Total timeframe includes project costs and municipal permits.
• Initial investment is higher than for a basic renovation.

So… which option is better?

It depends on your priorities. On the one hand, if you already have a home with potential and want to update it, renovating might be the right decision. On the other hand, if you're looking to create an efficient, modern home built to last, new construction using industrialized methods will be the option that offers the greatest value.

In both cases, having a team to guide you from design to completion makes all the difference.

At FILA, we can help you assess the best option for your specific needs. We conduct preliminary studies, design projects, and execute construction projects with a sustainable and efficient approach. We listen to you and evaluate your project with no obligation.

Choosing the right construction company is crucial for your project. Discover the 7 key steps to finding reliable, experienced professionals who meet your expectations.

Undertaking a construction project, whether it's your dream home, a complete renovation, or a new commercial space, is undoubtedly a significant investment of time, money, and expectations. Choosing the right construction company is, of course, one of the most critical decisions, as it will largely determine your success and peace of mind throughout the entire process. How can you ensure you choose the perfect partner? Below, we offer a step-by-step guide.

1. Clearly Define Your Project and Needs

Antes de buscar, tienes claro qué quieres construir, qué presupuesto aproximado manejas, los plazos deseados y tus prioridades (diseño, eficiencia energética, materiales específicos, etc.). Cuanto más detallada sea tu visión mejor podrás comunicar tus expectativas y evaluar si una constructora puede cumplirlas.

2. Thorough Research and Candidate Gathering

Personal recommendations: Ask friends, family, neighbors, or acquaintances who have completed similar projects, as firsthand experience is invaluable.
Online search: Use search engines with terms like "construction company in [your city/region]" or "home construction companies [type of project]" and also visit their websites and social media profiles.
Professional associations and organizations: They may offer listings of registered and qualified companies.

3. Evaluate Experience and Specialization

Third, not all construction companies are the same. Some specialize in single-family homes, others in renovations, or industrial projects.

Relevant experience: Have they completed projects similar to yours? Request a portfolio of their previous work.
Years in the industry: A company with years of experience in the sector is usually a sign of stability and expertise.

4. Verify Credentials and Solvency

Licenses and permits: Make sure the company is properly registered and has all the necessary licenses to operate in your area.
Insurance: They should have liability insurance that covers potential damages or accidents during construction.
Financial stability: A well-established construction company will have no problem paying its suppliers and workers. You can also request bank references (with their consent) or look for indicators of their financial health.

5. Request detailed quotes and compare

Request at least 3-4 quotes and make sure they are as detailed as possible, itemizing costs, materials, deadlines, and payment terms.

Don't just go for the lowest price: An excessively low quote could indicate a lack of experience, low-quality materials, or hidden costs. Compare the comparable: Verify that all quotes include the same services and quality.

6. Request references and visit previous projects

Don't rely solely on photos. Ask to speak with previous clients and, if possible, visit some of their completed or ongoing projects. Pay attention to the quality of the finishes, cleanliness, and organization of the worksite.

7. Communication and Trust are Key

Finally, during the selection process, evaluate the construction company's communication skills. Do they answer your questions clearly and promptly? Do you feel comfortable working with them? A good relationship of trust and fluid communication will be essential throughout the entire project.

Conclusion:

In short, choosing the ideal construction company requires time and careful analysis. But investing this initial effort will save you a lot of headaches and ensure your project is completed with the quality and professionalism you deserve. At FILA, we are committed to transparency, quality, and customer satisfaction. Let us be your trusted partner for your next project.

A clear comparison between prefabricated and industrialized buildings to help you make the best decision before building.

In recent years, the concept of housing has evolved. More and more people are looking for efficient homes that are quick to build and offer greater control over the construction process. In this context, we ask ourselves the following question regarding the two main players: prefabricated homes or industrialized construction?

Although sometimes used interchangeably, they are not the same. Understanding the differences is key before starting a project.

At FILA, with over 75 years of experience and a firm commitment to industrialized construction, we want to provide clarity so that everyone can choose the system that best suits their expectations, timeline, and lifestyle.

What is a prefabricated house?

A prefabricated house is made up of elements manufactured beforehand in a workshop or factory—panels, walls, structures, lightweight components—which are then transported to the building site for final assembly. This method reduces construction time and allows for more controlled costs.

Most common advantages

• Shorter construction times than traditional methods.
• Less material waste and a cleaner worksite.
• A more economical system, especially when working with standardized models.
• Predictable costs from the early stages.

Limitations to consider

Prefabricated houses usually start from predetermined designs and standardized modules, which implies:

• Less flexibility for customizing spaces.
• The project must adapt to the existing catalog, not the other way around.
• While there are exceptions, the site must meet certain characteristics to fit the system.

Prefabricated = cheaper, because its strength lies in repetition and standardization. This doesn't mean a lack of quality, but it does mean working within a predefined framework. Common materials: precast concrete, structural steel, SIP panels, and lightweight dry-assembly systems.

What is industrialized construction?

Industrialized housing takes things a step further. It's not just about manufacturing parts in a workshop, but about transforming the entire construction process into a highly controlled, precise, and technologically advanced system.
When we industrialize, design, manufacturing, and assembly function as a continuous chain, optimized through digital tools (BIM), automated processes, and factory quality control.
At FILA, we took this leap in 2020 to guarantee more efficient, safe, and durable homes, regardless of the weather, labor, or unforeseen circumstances of traditional construction.

Key advantages of industrialized construction

✔ Maximum control of the process from start to finish.

✔ Significant reduction in total construction time.

✔ Fewer errors, less waste, fewer accidents.

✔ Highly precise and reproducible finishes.

✔ Quick on-site assembly.

✔ The client designs the house, and the system adapts to it, not the other way around.

✔ Option to use sustainable materials such as wood, cellulose, or eco-friendly insulation.

✔ Adaptable to any type of terrain or climate, including slopes or challenging areas.

Industrialized doesn't mean "cheap." It means efficient, precise, and high-quality. You're investing in durability, comfort, and long-term performance. You're paying for a better home, not just a faster one.
