Reynaers vs Aluprof vs Schuco: Aluminum Systems Compared

U.S. projects increasingly spec "European aluminum windows" - then hit a wall of brand names and unclear differences. If you're wondering why developers choose European aluminum in the first place, start there. Once you're sold on the approach, the next question is: Is Schuco really "premium" compared to Reynaers? How does Aluprof stack up against Cortizo for steel-look?

Short answer: Reynaers, Schuco, Aluprof, Aliplast and Cortizo all make premium thermally broken aluminum window systems, and for a US project the right one is decided by sightlines, documentation and cost tier - not the logo. Reynaers (Belgium) has the broadest residential range and strong US-ready documentation. Aluprof (Poland) gives the best cost-to-performance and the lowest U-factors in its published data (down to U-0.11 on MB-86 AERO). Aliplast (Belgium) is the value pick for lift-and-slide and steel-look. Cortizo (Spain) leads on hidden sash and minimal sliders. Schuco (Germany) is the premium benchmark, strongest in commercial facades - it is in this guide as a comparison point, not a system I offer.

This guide cuts through the brand soup so you can compare the major players by what actually matters on your project.

Quick Context: Systems vs. Fabricators

Before comparing brands, know who does what:

• System House (Provider): Designs the profiles, thermal breaks, and hardware interface. Examples: Schuco, Reynaers, Aluprof, AluK, Cortizo. All of these produce aluminum window and door systems.
• Fabricator (Manufacturer): Buys those extrusions, cuts and assembles frames, integrates hardware and glazing, runs QC.

Key point: A strong system plus a weak fabricator equals problems. Always evaluate both. The logo on the profile is only half the story. The thermal break, for instance, is the system house's design decision - if you want to know what to look for in the profile drawing, see how thermally broken aluminum works. For a head-to-head look at how these systems benchmark against U.S. premium aluminum, see the comparison guide.

What to Compare (Not Logos)

Instead of brand reputation, compare the stuff that matters on site:

• Sightlines: Visible frame dimensions, corner options, steel-look detailing
• Performance ranges: Thermal, structural, water/air - varies by configuration. Understanding thermally broken aluminum construction is key to reading these specs correctly.
• Documentation: English submittal packages, test reports, BIM libraries. For U.S. projects, NFRC and NAFS certification readiness is critical. I host product brochures and DWG files for the major systems. If terms like DP rating, Uw, or CE marking are unfamiliar, the window glossary defines every one of them in plain English.
• Ecosystem depth: Hardware families, gaskets, finishes, compatible accessories
• Cost and lead time: Price tier, fabrication capacity, and import timelines

The Major Players at a Glance

Reynaers (Belgium): One of the most specification-friendly systems for U.S. imports. Broad range from tilt-and-turn windows (MasterLine 8/10) to minimal sliders (Hi-Finity). Strong documentation and hardware integration.

Schuco (Germany): Premium reputation, especially strong in curtain wall and commercial. Deep engineering documentation. ASE 60 and AWS series cover most needs. Included here as the comparison benchmark - Schuco is not a system I offer.

Aluprof (Poland): Excellent cost-to-performance ratio. MB-86 and MB-104 series suit multifamily and commercial well. Growing U.S. documentation support.

Aliplast (Belgium): Part of the Corialis Group, with production kept in Belgium. Strong value-to-performance: Genesis 75 for tilt-and-turn (U-0.15 with triple glazing), Max Light for steel-look, and the Ultraglide lift-and-slide for panels up to 970 lbs (440 kg).

Cortizo (Spain): Increasingly strong in minimal-sightline and steel-look applications. Competitive pricing for the aesthetic. The COR 70 Hidden Sash conceals the sash, the hinges and - with the Arch Invisible handle - the handle itself; the COR Vision sliders meet at a 0.79 in. (20 mm) central junction.

AluK (Italy/UK): Good value at the mid-market point. The 77 series works well where premium pricing is hard to justify.

Others worth knowing: WICONA/Technal (Hydro) for commercial facades, heroal for a German alternative to Schuco at a better price, Ponzio for steel-look packages.

The "right" choice usually comes down to fabricator capability, desired sightlines, and the documentation path for U.S. submittals - not the logo itself.

Common Head-to-Heads: Quick Answers

Aluprof vs Reynaers: which is better?

Reynaers is the more premium of the two, with the deeper residential catalog (MasterLine 8 and 10, SlimLine 38, Hi-Finity, MasterPatio) and higher U.S. documentation readiness. Aluprof sits one cost tier lower and posts the better best-case thermal numbers - U-0.11 (Uw 0.60) on MB-86 AERO against U-0.14 (Uw 0.78) on MasterLine 10 HI+. For a mid-budget custom home built mostly from tilt-and-turn and fixed units, Aluprof usually wins on value. For steel-look, minimal sliders or a large mixed package on one system, Reynaers is the safer single-system choice.

Reynaers vs Schuco

Both are premium system houses with deep engineering documentation. Schuco is strongest in curtain wall and commercial facades and sits in the top cost tier. Reynaers covers the same residential ground - tilt-and-turn, the SlimLine 38 steel-look line, minimal Hi-Finity sliders - and commonly comes in at a lower cost for similar aesthetics. On a U.S. residential project, Reynaers is the one I can price; Schuco is the benchmark it gets compared against.

Aluprof vs Schuco

Aluprof is the cost-to-performance option: MB-86 and MB-79N cover tilt-and-turn, casement and doors at a mid cost tier, and MB-79N also comes as a crank-out casement for U.S.-style outswing. Schuco has the deeper ecosystem and the premium price. If the project does not need a commercial facade range, Aluprof covers the residential window and door scope for less.

Aluprof vs Aliplast

Both sit in the value tier. Aluprof has the stronger thermal top end (MB-86 AERO, MB-79N SI) and the outswing crank-out casement. Aliplast is stronger on lift-and-slide (Ultraglide, panels to 970 lbs) and on steel-look (Max Light). I often price the same schedule on both and let the elevations decide.

Where does Cortizo fit?

Cortizo is the pick when an elevation should read as fixed glass. COR 70 Hidden Sash hides the operable sash behind the frame, with U-factors from 0.15 (Uw 0.84), and the Arch Invisible handle removes the last piece of visible hardware. For openings, the COR Vision and COR Vision Plus sliders keep the frame to a thin line. Cost tier is mid, alongside Aluprof and Aliplast.

Where Each Brand Tends to Fit

• Custom homes with minimal sightlines: Reynaers Hi-Finity/MasterPatio, Schuco ASE, Cortizo Cor-Vision. See the large glass and lift-slide doors guide.
• Urban multifamily: Reynaers MasterLine 8/10, Aluprof MB-86/MB-104, AluK 77 series.
• Steel-look retail/hospitality: Reynaers slim profiles or Ponzio steel-look window packages.
• Design-led residential on a budget: Cortizo and Aluprof deliver the clean look at a lower landed cost. See how to lower window costs.
• Facades where operable windows should read as fixed glass: Cortizo's concealed-sash platforms take the handle and hinges out of sight as well as the sash - see hidden sash windows. Reynaers offers a hidden vent variant on MasterLine 8 and 10 with conventional hardware.

Cost Ranges You Can Plan Around

The tier column in the table above is relative: premium systems cost more than mid-tier ones for the same opening, and the gap depends on the configuration. What moves the number within any system: triple glazing, oversize sashes, accessible thresholds, laminated make-ups, specialty hardware, coastal finishes and corner sliders.

For the supplied window itself, my estimator runs about $45 to $95 per square foot across the aluminum systems I quote - fixed lights at the low end, small operable sashes at the top, steel-look above - with freight, duty and installation on top. If you are budgeting a whole project rather than comparing brands, start with what European windows actually cost in the US for all-in landed ranges, or the per-square-foot breakdown in my aluminum window cost guide. New to these systems entirely? The complete US buyer's guide to European windows covers how the whole process works before you get to brand selection.

Whether a European system undercuts a domestic high-end brand depends on matched, dated quotes for the same openings, landed and installed. For the import cost layers, see European window import costs. If you are weighing these systems against US premium brands, I wrote an honest Marvin vs Pella vs European windows comparison.

Lead times: for the aluminum systems I quote, plan on roughly 9-16 weeks from approved shop drawings to site, confirmed per order; custom colors and complex glass can extend it - see European window lead times.

Why Multi-Source Matters

I work with Reynaers, Aluprof, Aliplast and Cortizo in aluminum, and Aluplast in uPVC. I'm not tied to any single brand - which means I can match the best system to each project based on design, performance, budget, and schedule. This independence is a key reason why developers import European aluminum windows through an agent rather than going direct.

I source the four aluminum systems I work with day to day - Reynaers, Aluprof, Aliplast and Cortizo - through the manufacturers that fabricate them, so if you have a window schedule, I will price it on the system that fits the project rather than the one a catalog happens to lead with. No schedule yet? The estimator gives you a ballpark landed range across the tiers in a couple of minutes. And if the design wants a wood interior rather than painted metal, the same openings can be quoted in aluminum-clad wood.

FAQs

What is the best European aluminum window system? There is no single best European aluminum window system - Reynaers, Schuco, Aluprof, Aliplast and Cortizo all make premium thermally broken systems. Reynaers has the broadest residential range, Aluprof the best cost-to-performance and the lowest published U-factors, Aliplast the value lift-and-slide and steel-look lines, Cortizo the cleanest hidden sash. Pick by sightline, performance target and fabricator, not by logo.

Is Reynaers more affordable than Schuco? Often yes - Reynaers commonly shows a cost advantage over Schuco at similar aesthetics, sitting in the mid-premium tier against Schuco's premium tier. Exact pricing depends on platform, glazing, finish, and schedule, so the fair test is the same window schedule priced on both systems with matched sightlines and glass.

Can Cortizo or Aluprof achieve the same minimal look? For many residential and light commercial projects, yes. Cortizo's COR 70 Hidden Sash and COR Vision sliders and Aluprof's MB-86 and MB-79N families deliver slim, clean elevations at a lower landed cost than the premium tier. See the uPVC vs aluminum guide for material-level comparisons.

Can European systems meet NFRC/NAFS requirements? NFRC-rated units are available on selected systems where the permit needs them, many configurations have NAFS test documentation, and in some jurisdictions European test reports are accepted alongside them. The key is having a partner who understands the compliance landscape and can navigate it for your jurisdiction. Discuss your specific needs early so I can confirm the right path. For a deeper look at how to evaluate a European window supplier on documentation readiness, see the dedicated guide.

Do you offer Schuco windows? No. Schuco is in this comparison as the premium benchmark, but it is not a system I quote. When a drawing set calls for Schuco, I price the same openings on Reynaers, Aluprof, Aliplast or Cortizo with matched sightlines and performance targets, so the architect and owner can compare the alternatives like for like before deciding.
