Aluminium windows
Slim profiles with a thermal break for maximum glazed area and a contemporary design. The rigidity of aluminium for large openings.
Schüco is a German benchmark in aluminium for building: slim profiles, large bays and flush-to-the-wall sliding systems. wendows is an authorised reseller and installer: a premium system, guaranteed, and fitted by our own teams — no middleman.
Schüco offers aluminium in windows, doors and large 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 contemporary design. The rigidity of aluminium for large openings.
Large flush-to-the-wall sliding systems to open fully onto the outside, with heavy leaves that move smoothly and a low, accessible threshold.
Aluminium doors with a clean design, matched to your windows, with multi-point security hardware and a good level of insulation. A coherent façade.
The aluminium profile takes double and triple glazing with a low Ug to aim for thermal excellence despite large glazed areas.
Beyond the aluminium material, it's the 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 slim mullions. Schüco is designed for very large glazed areas, where PVC reaches its limits.
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.
An insulating strip separates the inner aluminium from the outer aluminium, cutting the thermal bridge. That's what makes modern aluminium compatible with Belgian requirements.
Powder-coat lacquering across the whole RAL palette, in matt, satin or textured finishes, with two-tone inside/outside possible. Durable resistance to UV.
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 a large bay come down to the install. As authorised installers, our salaried fitters install Schüco systems to the manufacturer's rules, and we handle the warranty and after-sales directly.
Schüco 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. Schüco answers the first with premium German aluminium. In practice, it's the material you pick when you're aiming for large glazed areas: slim mullions, plenty of light and a clean design that lasts.
The brand is known for its large sliding systems and façades: aluminium is rigid, carrying heavy leaves where PVC sags. The built-in thermal break solves aluminium's old flaw — its conductivity — to reach good levels of insulation despite large bays.
"On a large aluminium bay, everything comes down to the install: a badly fitted Schüco system loses its weathertightness and its smooth action.
This is where our role as an authorised installer counts. We size the right Schüco 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 a large bay, weathertightness and alignment come down entirely to the install.
Built for very large bays. Thanks to the rigidity of aluminium and the thermal break, Schüco carries large glazed areas on slim mullions — where other materials reach their limits.
On budget, Schüco sits in the premium 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 Schüco fitted by our teams, grants deductible afterwards.

It's a German benchmark in aluminium for building, renowned for its slim profiles and its large bays. The appeal: large glazed areas, a clean design and robust systems. As with any brand, the final quality depends as much on the fitting as on the profile — which is why an authorised installer matters.
Aluminium naturally conducts heat, but the thermal break built into Schüco profiles corrects this flaw. Paired with good glazing, a modern aluminium window reaches excellent levels of insulation, while allowing bays far larger than PVC.
Yes, that's its strong suit. The rigidity of aluminium allows large leaves on slim mullions, and the brand offers flush-to-the-wall XXL sliding systems. It's the material of choice when you want to maximise the glazed area.
Because we're an authorised reseller and installer: it's our own teams who fit, to the manufacturer's rules, and we remain your single point of contact for the warranty and after-sales. On a large bay, weathertightness and alignment come down entirely to the install. We also handle your grants and the 6% VAT.
Depending on the range, the manufacturer warranty can run up to 10 years on the profiles and the standard hardware. wendows handles the follow-up and any work. The exact terms are set out on your quote.
Reckon on from around €800 for a fitted aluminium window; large sliding systems are quoted individually depending on the dimensions and the glazing. Grants and 6% VAT deducted afterwards.
