Who is Cortizo and why do they make PVC windows?
Cortizo is a Spanish manufacturer founded in 1972, headquartered in Padrón (A Coruña). For decades it has been one of the leaders in aluminium extrusion in Spain, with a consolidated distribution network throughout the country. Recently, Cortizo has entered the PVC market leveraging that same commercial infrastructure.
The question many clients ask us is straightforward: are Cortizo PVC windows as good as their aluminium? In this article we analyse the COR-70 system, real opinions from those who have installed them and whether it's worth choosing Cortizo PVC over German brands with more experience.
Cortizo COR-70 PVC system: technical analysis
The COR-70 is Cortizo's main PVC system. It's a standard-depth profile with the following specifications:
- Frame depth: 70 mm
- Chambers: 5 insulation chambers
- Uf value: 1.4 W/m²K (frame)
- Glazing: up to double glazing with 28 mm cavity
These are decent but modest specifications compared with German systems of 82–88 mm and 6–7 chambers. The COR-70 competes in the entry-level PVC segment, not the mid-to-high range where Veka or Kömmerling operate.
Cortizo aluminium vs Cortizo PVC: key differences
Cortizo's aluminium line has decades of experience and is a benchmark in Spain. Their aluminium systems with thermal break are common in new builds and mid-to-high-end renovations. PVC, on the other hand, is a more recent product in their catalogue.
The main difference is that Cortizo aluminium competes with Schüco and other premium brands, while Cortizo PVC competes in the budget segment. If your project is aluminium-based and you want to unify suppliers for certain rooms with PVC, Cortizo can make sense. For 100% PVC projects, we recommend also considering specialised brands.
Cortizo vs Kömmerling: head-to-head comparison
The most common comparison clients ask about is Cortizo vs Kömmerling. There are important differences:
- PVC experience: Kömmerling has over 50 years manufacturing PVC. Cortizo is relatively new to this material.
- Range of systems: Kömmerling offers 70, 76 and 88 mm systems. Cortizo only has the COR-70 (70 mm).
- PassivHaus certification: Kömmerling has PassivHaus-certified systems. Cortizo does not.
- Price: Cortizo is more affordable (from €260 installed). Kömmerling starts at around €320.
In summary: Cortizo wins on price, Kömmerling wins on performance and variety. For most residential projects in Girona and Costa Brava, Kömmerling offers better long-term value.
Real customer reviews of Cortizo PVC windows
After installing and evaluating Cortizo windows in several projects across the Costa Brava and Girona, these are the most common opinions from our clients:
What customers value most
- Competitive pricing: The most mentioned advantage. Cortizo PVC is one of the most affordable options on the market with acceptable quality.
- Spanish brand: Some clients value supporting national industry and the proximity of the manufacturer.
- Aluminium compatibility: Those who already have Cortizo aluminium can unify brand and finishes throughout the home.
- Distribution network: The same network that works for aluminium facilitates access to Cortizo PVC across many areas of Spain.
What customers like least

- Little variety: Only one system (COR-70) versus the 3–4 systems offered by brands like Kömmerling or Ecoven Plus.

Who are Cortizo PVC windows for?
Cortizo PVC is an option to consider when the budget is very tight and mid-to-high-range technical performance isn't needed. It also makes sense when you already have Cortizo aluminium in the property and want to unify suppliers for certain rooms.
For new projects where PVC is the main choice, we recommend considering brands with more experience and variety of systems. In our comparison of the 6 best manufacturers you can see the alternatives in more detail.
Conclusion: is Cortizo PVC worth it?
Cortizo is a solid company with an impeccable track record in aluminium. Their PVC line is correct but modest, aimed at the budget segment. If price is your absolute priority, it can be a reasonable option.
However, if you're looking for the best long-term value in PVC, brands like Kömmerling, Veka or Ecoven Plus offer more advanced systems, longer warranties and better insulation. At Instal Tancaments we work with all these brands and can advise you on your project in the Costa Brava and Girona.
