Reynaers Aluminium is a Belgian company that engineers the aluminium systems used to make windows and doors, commercial storefronts and facade systems. A “system” is the complete kit: thermally broken profiles, gaskets, hardware and the rules for putting them together. Reynaers does not make finished windows and it does not make glass. A fabricator builds each unit to the project’s sizes, and the glass is chosen separately for the building: double or triple, low-E, laminated or acoustic.
The main ranges are MasterLine 8 (the high-insulation window and door platform), SlimLine 38 (slim, steel-look profiles), CS 77 (the established all-round window and door system), the Hi-Finity and ConceptPatio sliding doors, and the ConceptWall curtain wall. We compare the three window systems in MasterLine 8 vs SlimLine 38 vs CS 77, and the brand against others in Reynaers vs Alutech and Reynaers vs Schüco.
Reynaers Aluminium is a Belgian system house: it designs the profiles, hardware and gaskets and sells them to approved fabricators, who make the windows. It does not sell finished windows to the public, and in the United States there is no Reynaers showroom to walk into. So the practical question — where do I get Reynaers windows in New York? — has one answer: from a fabricator-installer. Alex GC fabricates Reynaers systems at our Staten Island shop and installs them across New York City, Long Island and New Jersey. We take the architect’s schedule to shop drawings, make the units, and put them in.
What that means for a project: one company responsible for the window from the extrusion to the sealant joint; lead times of roughly eight to twelve weeks from approved drawings (profiles ship from Europe); black, anodised or any RAL colour; and pricing that reflects a premium European system — more than vinyl or a domestic aluminium line, in exchange for the slimmest sightlines and the largest sashes available. The ranges we fabricate are below (and compared head-to-head in MasterLine 8 vs SlimLine 38 vs CS 77); the Ocean Parkway house shows the result.
Reynaers Aluminium is a Belgian systems house, and "Reynaers" on a specification is not specific enough to price against. The company designs profile systems that fabricators build to; which system is named determines the sightline, the glazing capacity and the thermal result. The ranges below are the ones available for the North American market.
MasterLine 8 is the principal window and door range, with a wide set of door configurations including panel, passive, balcony and panic doors, and the pivot doors that come up constantly on high-end residential work. It is the range most often specified where the opening has to be both large and thermally serious.
MasterLine 10 is the more recent generation of the same family.
SlimLine 38 is the narrow-sightline range, using a deep thermal break with slender profiles. It is offered in Classic, Ferro and Cubic design variants, which matters because Ferro is the steel-look option — the one to reach for when the building wants the appearance of a steel window without steel's thermal behaviour. SlimLine 68 sits above it with more capacity.
CS 77 and the wider ConceptSystem family (CS 68, CS 86-HI) cover commercial and higher-insulation applications. CS 59Pa and ES 45Pa are non-thermal systems, correct for interior partitions and internal commercial doors and wrong for anything on the building envelope.
Hi-Finity is the minimal-sightline sliding range, available in two-rail, three-rail, pocket and open-corner configurations, with a high-insulation variant. It is what gets specified when the brief is the largest possible glass and the least possible frame.
ConceptPatio 130 and ConceptPatio 155 are the lift-and-slide systems, with burglar-proof and open-corner options. SlimPatio 68 and ConceptPatio 68 are the lighter-duty options, MasterPatio the newer range, and ConceptFolding 77 the folding system.
CW 50 is the stick-built curtain wall system — mullion-drained, with fireproof, high-insulation, slimline, structural-glazed and structurally-clamped variants, and an aluminium-on-steel option where the structural demand exceeds what aluminium alone will carry. CW 60, CW 65 EF and CW 86 extend the range, and ElementFacade 7 is the unitised system for buildings where the facade is assembled off site and hung as panels.
European systems are engineered and tested to EN standards. For New York work the questions that matter are whether the specific configuration has the NFRC ratings the energy code requires, whether the tested size limits cover the opening you actually have, and whether the hardware you want is inside the tested assembly. A system can be excellent and still be wrong for a particular opening if the size exceeds what was tested, and that is a question to settle before ordering rather than after.
We carry multiple premium manufacturers for these products including:
Each brand offers distinct advantages in performance, design, and price point. We can help you choose the perfect fit for your project.
Proper installation is critical for optimal performance. Our installation team provides:
Installation includes sealing and flashing the perimeter of the opening, because a window is only as watertight as the junction between it and the building. Where an opening needs more than that — a failed sill, damaged masonry, a detail that was wrong to begin with — see waterproofing.
Which Reynaers range suits a job depends heavily on the building stock, and Brooklyn's varies sharply over short distances. The notes below describe what the areas typically call for.
The stretch of Fifth Avenue around 14th Street sits where South Slope meets Greenwood Heights, with Gowanus just to the north-west. It is a mix: nineteenth-century rowhouses on the side streets, older commercial frontage along Fifth Avenue itself, and newer infill and conversions.
That mix pulls in two directions. Rowhouse work in the Park Slope Historic District is governed by the landmarks approval, and the narrow-sightline SlimLine range — particularly the Ferro steel-look variant — is often the closest aluminium equivalent to an original profile. On the avenue, commercial frontage and conversions are a CS 77 or curtain wall question instead. Two buildings a block apart can need entirely different systems.
Ocean Parkway at Avenue W runs through Gravesend towards Homecrest and Sheepshead Bay — largely detached and semi-detached houses, two- and three-family homes, and a good deal of substantial new residential construction.
Two things shape the specification here. Ocean Parkway is a major arterial, so acoustic performance matters on the elevations facing it, and Reynaers systems use a centre gasket and acoustic seal that helps once it is paired with the right glass. And the area runs close enough to Coney Island Creek and Sheepshead Bay that salt exposure is real: the finish specification and the fixings deserve attention, and the coating question is worth asking about directly. New-build houses here also tend to want large sliding openings to rear gardens, which is Hi-Finity or ConceptPatio territory.
Williamsburg is the clearest case for the commercial and unitised end of the range. Converted industrial buildings carry large openings that were originally steel, and new residential towers along the waterfront and through the northside want floor-to-ceiling glazing.
For a warehouse conversion, the SlimLine Ferro variant addresses the steel-look question in the original openings. For new build, CW 50 stick curtain wall or ElementFacade 7 unitised is the conversation, and on the waterfront the wind pressure is high enough that the design pressure comes from the engineer rather than from a catalogue. Hi-Finity comes up constantly for terrace and balcony openings where the view is the point.
We supply and install Reynaers systems across Manhattan, Brooklyn, Queens, the Bronx and Staten Island, and throughout Northern New Jersey, the Jersey Shore, Philadelphia and the Lehigh Valley. If you have a system named on a drawing we will quote against it. If you have an opening and a performance requirement but no system named yet, tell us the address, the elevation and what the opening has to do, and we will tell you which range fits — including when a different manufacturer would suit the job better.
From an approved fabricator-installer; Reynaers sells systems to fabricators, not finished windows to the public. Alex GC fabricates and installs Reynaers in New York City, Long Island and New Jersey.
No public showroom. The route is a fabricator: we can show installed projects in Brooklyn and samples of the profiles and finishes at our Staten Island shop.
About eight to twelve weeks from approved shop drawings. Profiles and hardware ship from Europe; fabrication is done at our shop.
More than domestic aluminium lines such as Crystal or Everest and considerably more than vinyl; comparable to Cortizo and other premium European systems. We quote from drawings or a survey.

No. Reynaers makes the aluminium framing system: profiles, gaskets and hardware. The glass is specified for each project and supplied by a glass manufacturer, then glazed into the frames by the fabricator. That is why two Reynaers windows of the same series can have very different glass.
MasterLine 8 is the high-insulation window and door platform, SlimLine 38 gives slim steel-look sightlines, and CS 77 is the established all-round system. Our side-by-side comparison page sets out where each one fits.
