Reynaers
Big glazing, sliding walls and modern facades
Reynaers has spent decades solving the same problem: how to make a very large piece of aluminum-framed glass move well, seal properly and still look thin. Its reputation among fabricators rests on hardware that behaves and systems that hold their tolerances.
For a rear extension with a wide slider or a facade of tall windows, that is the whole conversation.
Who they are
A Belgian aluminum system house based in Duffel, supplying windows, doors, sliding and folding systems and curtain walling through a network of fabricators.
Materials and system families
ConceptSystem 77 is the general-purpose thermally broken window system. MasterLine 8 is the flagship — described by the company as its most trusted window system worldwide — with slim sightlines and a wide range of opening types and finishes.
Which properties it suits
- Wide sliding or lift-and-slide openings onto a yard or terrace.
- Modern facades with tall, repeating window bays.
- Multi-family and mixed-use buildings needing windows and curtain wall from one system family.
How it differs from the other brands here
Reynaers is strongest where openings get large and movement matters. Schüco is its closest peer on documentation, Aluprof on value; none of the American brands on this list plays in quite the same architectural-aluminum territory.
What to confirm for your own openings
A brand is a starting point, not a specification. Before Reynaers is the right answer for your home, a handful of details need to be settled at the opening itself.
- Which series within the brand is actually available for your opening size and configuration.
- Frame material and depth against the existing jamb, and whether the install is insert or full-frame.
- Glazing package — coatings, gas fill, laminated or acoustic glass for a busy street.
- Hardware, screens and finish, inside and out, so the window matches the room and the facade.
- Lead time from approved drawings to delivery, and what happens on install day.
