Aluplast vs. Cortizo: Which Aluminium Profile Is Right for Your Project?

When choosing windows and doors, the frame behind the beauty matters more than you think. At AtoZ Design and Glass, we’ve worked with every profile under the sun — and two names come up often: Aluplast and Cortizo.

But not all aluminium is created equal. Here’s the truth.

🔍 The Big Difference: Material and Engineering

Cortizo Aluminium:

Made in Spain with its own proprietary alloy.
Trusted by architects across Europe for high-end residential and commercial projects.
Allows slim sightlines without compromising strength.
Thermal break integration for top-tier energy efficiency.
Finishes are architectural-grade with longer lifespan.

Aluplast Aluminium (often confused with their PVC products):

More budget-friendly and used for entry-level builds.
Limited in terms of design flexibility and frame dimensions.
Shorter lead life, especially in aggressive weather zones.

🛡️ Why AtoZ Chooses Cortizo

We partner with factories using Cortizo because we don’t compromise on:

Thermal performance — clients demand U-values that protect their bills.
Aesthetics — slim, sharp profiles create seamless glazing.
Longevity — aluminium that doesn’t corrode or distort under pressure.

And with AtoZ, you get Cortizo quality at a price often 10–30% better than local suppliers thanks to our cross-border production model.

💸 The Hidden Cost of "Cheaper"

We’ve had clients choose cheaper profiles — only to replace them 2–4 years later due to condensation, warping, or coating issues. That’s not saving. That’s stress.

🧠 Architects, Here's Why It Matters

Specifying Cortizo means:

No callbacks from clients due to product failure.
Fast access to CAD files, thermal docs, and compliance certifications.
Consistent finishes across curtain walls, sliders, and casements.

✅ Final Verdict: Cortizo Wins on Every Metric
