Who is Cortizo and why is it a benchmark in PVC?

Cortizo is a Spanish manufacturer founded in 1972, headquartered in Padrón (A Coruña). With over 50 years of experience in joinery and revenues exceeding 800 million euros, it is one of Spain's most important industrial companies. Their decades of aluminium expertise has given them an exceptional technical foundation that they now apply to PVC with outstanding results.

What many don't know is that Cortizo has been manufacturing PVC profiles for over 20 years and their current catalogue is one of the most comprehensive on the market: systems of 70, 78 and 84 mm, with PassivHaus certification across several ranges and insulation values that match or exceed the most renowned German brands. All made in Spain.

In this article we analyse each system in detail, our clients' feedback after years of installing Cortizo PVC and why we consider it an excellent alternative to German brands. If you want to compare with other brands, check our ranking of the 6 best PVC window manufacturers.

Cortizo PVC Systems: complete range from 70 to 84 mm

Cortizo offers a PVC range broader than most people imagine. 3 profile depths, hidden sash systems, sliding and lift-and-slide options, and multiple energy certification choices:

Cortizo A 70: the all-rounder for renovations

The A 70 is Cortizo's entry-level PVC system, but "entry-level" doesn't mean basic. With 70 mm depth, 5 chambers and a Uw from 0.9 W/m²K, it outperforms many mid-range systems from other brands in insulation.

  • Depth: 70 mm with 5 insulation chambers
  • Thermal transmittance Uw: from 0.9 W/m²K — better than many 76 mm systems
  • Acoustic insulation: up to 46 dB (Rw)
  • Glazing: up to 42 mm (double or triple glazing)

Available in tilt-and-turn, casement, folding and tilt-and-slide versions. There is also the A 70 Hidden Sash variant with only 66 mm visible section — practically all you see is glass.

Cortizo A 78: upper mid-range with PassivHaus option

The A 78 is a 78 mm system with 6 chambers offering high-end performance. It features improved joints and accommodates glazing up to 48 mm. Most notably, it has a certified PassivHaus version for warm-temperate climates (ideal for southern Europe).

  • Depth: 78 mm with 6 chambers
  • Thermal transmittance Uw: from 0.80 W/m²K (standard) / from 0.74 W/m²K (PassivHaus)
  • Acoustic insulation: up to 46 dB (Rw)
  • Glazing: up to 48 mm (triple glazing)
  • PassivHaus certification: Yes — warm-temperate category (Iberian Peninsula)

The A 78 PassivHaus is a very attractive option for new builds with demanding energy requirements. Its price is noticeably lower than PassivHaus systems from German brands.

Cortizo A 84 PassivHaus HI: top performance on the market

The A 84 PassivHaus HI is Cortizo's flagship PVC system and one of the most advanced systems on the market, regardless of brand. Certified by the Passive House Institute for the cool-temperate category, it incorporates special insulating foams.

  • Depth: 84 mm with 6 chambers + insulating foams
  • Thermal transmittance Uw: from 0.66 W/m²K — among the best values on the market
  • Acoustic insulation: up to 46 dB (Rw)
  • Glazing: up to 56 mm
  • PassivHaus certification: Yes — cool-temperate category

With a Uw from 0.66 W/m²K, the A 84 PassivHaus HI competes directly with the best systems from Kömmerling and Veka. A system of this level manufactured in Spain is truly exceptional.

Cortizo PVC Sliding Systems

Cortizo completes its PVC range with sliding systems:

  • C 70 Sliding: 70 mm sliding system, ideal for terrace and balcony access.
  • E 170 Lift-and-Slide: Cortizo's premium lift-and-slide system for large glazed areas.

Advantages of choosing a Spanish brand like Cortizo

Beyond technical performance (which as we have seen is top-tier), choosing Cortizo has important strategic advantages:

  • Shorter delivery times: Manufacturing in Spain means profiles arrive in 2-3 weeks versus the 4-6 weeks typical of German brands.
  • Immediate after-sales service: If you need a replacement or technical support, Cortizo responds in days, not weeks.
  • Lower carbon footprint: Not importing from Germany significantly reduces the transport carbon footprint.
  • Compatibility with Cortizo aluminium: If your home already has Cortizo aluminium, you can unify brands for all joinery.
  • More competitive pricing: Cortizo can offer systems with equivalent performance at 10-20% lower prices than German brands.

Cortizo vs German brands: an honest comparison

The question our clients ask most: Is Cortizo PVC as good as Kömmerling or Veka? The short answer is: yes, the technical performance is equivalent.

Let's compare real data: the Cortizo A 70 achieves Uw 0.9 W/m²K with 5 chambers and 70 mm — comparable to the Kömmerling 76 AD. The A 78 PassivHaus achieves Uw 0.74. And the A 84 PassivHaus HI with Uw 0.66 is among the best values in the world market.

Where German brands like Kömmerling have the edge is in finish variety and brand recognition. Veka stands out for its exclusive SPECTRAL ultra-matt finishes. Where Cortizo wins is in price, delivery times and after-sales service.

Our recommendation: if a premium finish is your priority, look at Kömmerling Full Cover or Veka SPECTRAL. If you want the best performance-to-price ratio with fast service, Cortizo is an excellent choice. In any case, what matters most is who fabricates and installs your window.
