Aluminum or PVC Windows, Which are Better?

The choice between aluminum and PVC windows will be guided by the architectural style of the project.

La carpintería de aluminio de alta calidad, es la más demandada por los arquitectos y constructores a día de hoy en España.

At Dekovent, we will provide a comparison between PVC and aluminum windows.

When starting a project or construction, the choice of doors and windows is often one of the most important factors to consider. They will define the design direction, guided by the architectural style of the project.

The materials used in the joinery of your project will have a direct impact on the energy efficiency of the building once it is completed.

Therefore, many people wonder, which is better, PVC or aluminum joinery?

When to choose Aluminum Windows or PVC?

Between these two types of windows, there are material and structural differences: weight, thermal insulation, design, maintenance, durability…

Both have interesting characteristics to consider. We explain the main differences between them and when it is more advisable to choose one or the other.

When to Choose Aluminum Joinery?

Aluminum is a lightweight, modern, and highly resistant material. But what advantages do aluminum windows present?:

For modern and minimalist constructions: it is suitable for spacious areas with modernist architecture where design is paramount. Aluminum offers unique finishes and allows for larger glazed areas and more modern windows with increased natural light.
For constructions such as curtain walls: These types of constructions typically have large glass facades. Therefore, they require very resistant and rigid structures capable of supporting the weight of these glass panels and structures.
It is highly resistant to impacts and pressures: if you are building a house in a windy area such as the beach or coast, this type of joinery becomes very interesting. Aluminum is a very resistant material that does not deform under the pressure exerted by wind against the structures.
Thermal and Acoustic Insulation: With the advent of thermal break technology, aluminum can adapt to all climates and temperatures. With a wider and deeper structure, you ensure 100% insulation of the house, resulting in long-term savings as you won’t need to invest in heating or cooling.
Excellent resistance over time: Aluminum has a natural coating that protects it from rust and external aggressions that could damage the window.
Non-flammable: Aluminum is a material that does not ignite, providing extra protection and safety to the building or space.
Low maintenance: Aluminum requires minimal maintenance compared to other materials. Therefore, its care and maintenance over time do not entail high costs.

As you may have noticed, aluminum is an excellent option at all levels. At Dekovent, we specialize in this type of metal joinery for modernist projects with renowned architects. Aluminum is a trending material that continues to grow in demand by the most demanding profiles in the sector.

When to Choose PVC Joinery?

PVC windows are also widely used today compared to other more traditional materials. PVC is a natural insulator and provides excellent noise insulation. Here are its main advantages when choosing it:

More resistant and durable than wood: PVC windows offer better insulation against weather conditions compared to wood. Like aluminum, it is highly resistant to external conditions.
In Extreme Climates: In very cold or very hot areas, PVC windows are often used due to their insulating properties.
Good thermal insulation: PVC windows offer very good thermal insulation, comparable to premium aluminum windows or those with thermal break technology.
Versatile in terms of opening systems.

As you can see, both PVC and Aluminum Windows yield excellent technical results.

What is true, however, is that high-quality aluminum joinery is currently the most demanded by architects and builders in Spain. This type of joinery offers much greater versatility when adapting to modernist and minimalist architectural designs, where design is highly relevant.

At Dekovent, we work with leading global premium brands in aluminum joinery. You can see these types of windows and joinery integrated into projects here.
