Choosing the right windows during a complete renovation is a key decision. It affects not only the aesthetics of the home, but also the thermal insulation, energy efficiency, acoustic comfort and durability of the house. In Barcelona, where the Mediterranean climate combines humidity, intense sunshine and mild temperatures, it is especially important to choose the right type of carpentry. If you are considering renovating your windows and you are hesitating between aluminum or PVCThis comparison will help you make an informed decision.
1. Aluminum windows: modern design, strength and durability
Aluminum is a material widely used in contemporary architectural projects because of its robustness, its long service life and its clean and elegant aesthetics. Today, aluminum windows include thermal break (RPT)a solution that considerably improves insulation.
Advantages
-
Superior structural strengthideal for large windows or sliding doors
-
Long durability no deformation or oxidation
-
Minimal maintenance
-
Wide variety of finishesincluding wood effect or matte lacquered
-
Stylized designwith slim profiles that provide more light.
Inconveniences
-
Higher price (especially with RPT systems)
-
Without RPT, it can generate thermal bridges and condensation.
When to choose aluminum windows?
If you are renovating a house exposed to the sun, with large openings or you are looking for a modern and minimalist aesthetic, aluminum with RPT is the most suitable option. It is also recommended for exterior facades, penthouses or coastal areas, common in neighborhoods such as Eixample, Gràcia or Poblenou. You can learn a little more about the neighborhoods in our post on "Neighborhoods with greater opportunities for entrepreneurship".
2. PVC windows: insulation and energy efficiency at a good price
PVC is a non-conductive plastic material that stands out for its thermal and acoustic insulation capacity. It is a very effective solution for homes seeking energy efficiency without compromising the budget.
Advantages
-
Excellent thermal and acoustic insulationwithout the need for additional systems
-
More affordable price compared to high-end aluminum
-
Zero maintenance
-
High tightnessideal for interior floors or wet areas
Inconveniences
-
Lower structural stiffness, not recommended for very large openings
-
Less variety of finishes (although today there are more options than in the past)
-
May deteriorate over time if the quality of the profile is not high
When to choose PVC windows?
If your home has small or medium-sized openings, shaded orientation or is located in interior courtyards, PVC can offer very good performance at a lower cost. It is ideal for practical and functional renovations.
3. Practical comparison: aluminum or PVC?
Thermal and acoustic insulation: PVC gains in thermal performance due to its low conductivity, although aluminum with RPT matches it in quality ranges.
Durability and resistance: Aluminum withstands better the passage of time, solar radiation and external agents. It is ideal for very exposed exteriors.
Aesthetics and customization: Aluminum offers more versatile finishes and more minimalist designs. It is a better choice in projects where design is key.
Value for money: PVC offers an excellent cost/insulation/comfort ratio, although with fewer aesthetic options.
4. Which one is better for a renovation in Barcelona?
Barcelona has climatic conditions that demand durable, efficient and adaptable materials. For high-end renovations or large openings, aluminum with RPT is the preferred choice for its design and resistance. For more compact projects or when thermal insulation is a priority with a more limited budget, PVC more than fulfills its function.
In any case, the professional installation is essential for both systems to meet their performance requirements. A poorly installed window, whatever the material, will lose efficiency and durability. Therefore, we recommend you read our post on tips for organizing an integral reform, here.
Conclusion
The choice between aluminum or PVC windows depends on several factors: the type of house, the environment, the budget and the aesthetic result sought. Both options can be valid if quality materials are combined with technical advice.
