Reynaers Aluminium is a major Belgian player in architectural aluminium: slim profiles, large bays and minimalist systems for contemporary façades. wendows is an authorised reseller and installer: a premium system, guaranteed, and fitted by our own teams — no middleman.
Reynaers offers aluminium in windows, doors and large minimalist sliding systems with a thermal break. Here are the families we fit most often in Belgium — each chosen on site to suit your project.
Slim profiles with a thermal break for maximum glazed area and a clean architectural design. The rigidity of aluminium for large openings.
Large minimalist sliding systems with very slim mullions to open fully onto the garden, with heavy leaves that move smoothly and a flat threshold.
Aluminium doors with an architectural design, matched to your windows, with multi-point security hardware and a good level of insulation. A coherent façade.
The Reynaers aluminium profile takes double and triple glazing with a low Ug to aim for thermal excellence despite very large glazed areas.
Beyond the aluminium material, it's the architectural slimness of the profiles and the thermal break that make the difference. The benchmarks specific to the brand, fitted by our teams.
Aluminium is rigid: it carries large leaves on very slim mullions. Reynaers is designed for very large glazed areas and demanding architectural projects.
The profile's thermal break, paired with triple glazing, lets aluminium reach a very good level of insulation despite its natural conductivity.
Manufacturer warranty on the profiles and the standard hardware, depending on the range. wendows handles the follow-up directly if work is ever needed.
Reynaers is a Belgian player in architectural aluminium, present internationally. A relatively short supply chain and parts availability tracked over the long term.

Multi-point locking as standard, rigid profiles that are hard to force and optional anti-intrusion laminated glazing for the ground floor and large bays.

Buying a good aluminium system isn't enough: the performance and weathertightness of an XXL bay come down to the install. As authorised installers, our salaried fitters install Reynaers systems to the manufacturer's rules, and we handle the warranty and after-sales directly.
Reynaers isn't our only option. Depending on your project and budget, other window brands may suit you better. Compare them, then we'll decide together on site.

See prices & grants →When you replace your windows, you choose two things: a system and an installer. Reynaers answers the first with Belgian architectural aluminium. In practice, it's the material you pick for contemporary projects: very large bays, very slim mullions and a minimalist design that gives structure to the façade.
The brand is known for its minimalist systems and its XXL sliding doors: aluminium is rigid, carrying heavy leaves where PVC sags. The built-in thermal break corrects aluminium's natural conductivity to reach good levels of insulation despite large glazed areas.
"A minimalist XXL bay forgives no fitting flaw: it's the install that guarantees the weathertightness and the smooth action.
This is where our role as an authorised installer counts. We size the right Reynaers bay or window for each opening, fit to the manufacturer's requirements and remain your single point of contact for the warranty, adjustments and after-sales. On an XXL bay, weathertightness and alignment come down entirely to the install.
Built for the widest bays. Thanks to the rigidity of aluminium and very slim architectural profiles, Reynaers carries very large glazed areas with a minimalist design — where other materials reach their limits.
On budget, Reynaers sits in the architectural aluminium segment: the gap mostly comes down to the size of the bay, the type of sliding system and the glazing chosen. To place your project, start from our window prices & grants page, then ask for a costed quote, opening by opening.
The price depends mainly on the size of the bay, the type of opening and the glazing — not just the brand. Here are starting ranges for Reynaers fitted by our teams, grants deductible afterwards.

It's a major Belgian player in architectural aluminium, renowned for its minimalist systems and its large bays. The appeal: very large glazed areas, a contemporary design and robust profiles. As with any brand, the final quality depends as much on the fitting as on the profile — which is why an authorised installer matters.
