Umfassender Fenster- und Türenaustausch – vom Aufmaß bis zur Montage
Wir wählen energieeffiziente Fenster aus PVC und Aluminium, moderne Schiebesysteme sowie robuste Eingangstüren aus, liefern diese und übernehmen deren fachgerechte Montage – und das in ganz Luxemburg. Unser Angebot umfasst maßgeschneiderte Lösungen sowohl für die Modernisierung von Bestandsgebäuden als auch für Neubauten: von klassischen Fenstern bis hin zu großflächigen Terrassenverglasungen, die für mehr Tageslicht sorgen und den Wohnraum harmonisch mit dem Garten verbinden.
Wir beginnen jedes Projekt mit einer sorgfältigen Bestandsaufnahme und der genauen Erfassung der Bedürfnisse der Bewohner. Wir unterstützen bei der Auswahl des passenden Materials, der Verglasungsart, der Öffnungsvariante, der Farbe, der Beschläge sowie der Zusatzausstattung. Dabei achten wir nicht nur auf die Optik, sondern vor allem auf Wärme- und Schalldämmung, Sicherheit und den Wohnkomfort im Alltag.
Wir sorgen für eine sorgfältige Montage, fachgerechte Abdichtung und Justierung aller Komponenten. Zudem unterstützen wir bei der Prüfung der Förderfähigkeit im Rahmen verfügbarer Programme in Luxemburg und bereiten die Unterlagen für die geplante Renovierung vor. Dies gestaltet den gesamten Ablauf – von der Auswahl der Lösung bis zur Fertigstellung – für den Kunden einfacher, transparenter und gut geplant.
Wussten Sie, dass …
Das neue Fenster verändert nicht nur das Erscheinungsbild der Fassade
Ein kühler Bereich am Fenster, Zugluft, Straßenlärm, Kondenswasser an den Scheiben und ein hoher Energieverbrauch deuten oft darauf hin, dass die Fensterrahmen nicht mehr den heutigen Anforderungen entsprechen. Gut gewählte Fenster und Türen tragen dazu bei, Wärmeverluste zu verringern, die Luftdichtheit des Gebäudes zu verbessern und das ganze Jahr über für ein angenehmes Raumklima zu sorgen.
Die Produktqualität allein macht jedoch nur einen Teil des Ganzen aus. Ebenso wichtig sind präzise Aufmaße, die Abstimmung der Lösung auf Wand und Dämmung sowie fachgerecht ausgeführte Anschlussfugen. Deshalb betrachten wir bei Voltmax den Austausch von Fenstern und Türen als Teil einer umfassenden Haussanierung – und nicht bloß als den Austausch eines Rahmens gegen einen anderen.

Beschreiben Sie kurz, was Sie benötigen. Sie können Fotos Ihrer aktuellen Fenster oder Türen hinzufügen – wir werden uns bei Ihnen melden, um die Maße und möglichen Optionen zu besprechen.
Ihre Vorteile:
Wärme und geringere Energieverluste
Moderne Profile, Dreifachverglasung und eine fachgerechte Montage tragen dazu bei, den Innenraum im Winter warm zu halten und ein Überhitzen im Sommer zu reduzieren.
Mehr Stille
Sachgemäß ausgewählte Verglasungen, Dichtungen und Profile reduzieren die Schallübertragung. Dies ist besonders wichtig an stark befahrenen Straßen, in dicht bebauten Gebieten oder in der Nähe von Flughäfen.
Sicherheit und Komfort
Verstärkte Profile, Verriegelungspunkte und bewährte Beschläge erhöhen den Schutz, während sorgfältig ausgewählte Mechanismen das tägliche Öffnen selbst großer Flügel erleichtern.
Auf Ihr Zuhause abgestimmtes Design
PVC, Aluminium, schlanke Rahmen, großflächige Verglasungen, Farben in Holzoptik und eine breite RAL-Palette ermöglichen es Ihnen, den Charakter des Gebäudes zu bewahren oder ihm ein modernes Erscheinungsbild zu verleihen.

Large glazing and access to the terrace
More light, a comfortable passage to the garden and an open living space – the sliding system should be selected not only to suit the size of the opening, but also to the way the terrace will be used, the expected threshold and the budget.
PSK PVC - Slide and Tilt Function
An economical patio solution based on proven profiles. The tilt-and-slide mechanism allows for the comfortable movement of sashes weighing up to 200 kg, and the glazing unit can be up to 52 mm thick.
SLIDE PVC - a door leaf that opens parallel to the wall
A good solution when you want more space in the room. The sash doesn’t extend into the interior like in traditional balcony doors. The system can create structures up to approximately 4 meters wide and 2.6 meters high, depending on the configuration.
HS PVC - large doors and a comfortable low threshold
The lift-and-slide system allows for the construction of large patio doors—up to approximately 6 meters wide and 2.8 meters high. The mechanism facilitates the operation of doors weighing up to 400 kg, and the floor-integrated threshold improves the comfort of passage.
HS ALU - maximum light in a visually lightweight structure
The rigidity of aluminum allows for the creation of extensive glazing with modern proportions. Structures up to 6 meters wide and the ability to conceal the threshold in the floor are ideal for designs that open the living room to the terrace or garden.
Entrance doors
FIRST IMPRESSION. EVERYDAY COMFORT. A QUIETER HOME.
Entrance doors that complement the building’s style
Exterior doors should combine appearance with weather resistance, stability, insulation, and convenient closing. At Voltmax, we help you choose the material, color, panel, glazing, pull handle, hinges, and locking system to complement the facade and the way your home is used.
PVC doors – warm, stable, and versatile
Profiles reinforced with a 3 mm wide closed steel element;
HPL panels up to 62 mm thick, optionally with aluminum inserts;
Various hardware options, including automatic locking upon closing;
Hinges: swing, roller, or concealed;
Low aluminum threshold with thermal break.
ALUMORE STANDARD aluminum doors – a custom look
Aluminum provides high resistance to temperature changes and allows for the perfection of every detail. You can choose a color from a wide RAL palette, panel model, pull handle, hinges, and locking system – from classic to automatic or electronic options.
ALUMORE DOOR — Design and Technology
A line for those who want to combine minimalist form with advanced details. The overlay panel construction is weather-resistant, and standard locking at three key points enhances security. Standard, 3D, and Dual versions are available, along with optional opening solutions: fingerprint reader, touch panel, keypad, or Smart Home integration.
FIRST CHECK THE CONDITIONS. THEN ORDER AND INSTALL.
Klimabonus and assistance with formalities
Window replacement can be part of a subsidized energy retrofit.
In Luxembourg, replacing windows and balcony doors may qualify for the Klimabonus program if the building and the planned solution meet current technical and formal requirements. Window replacement can also improve a home’s energy performance, but it does not guarantee a specific energy class—the result depends on the entire building, its insulation, ventilation, and heating system.
Voltmax helps streamline the process: we review the project scope, the parameters of the proposed products, and the documents required to verify eligibility for subsidy. If cooperation with an energy consultant is required, we include it in the work schedule.
What you should know about the 2026 rules
- The program covers residential buildings in Luxembourg older than 10 years;
- Window replacement can be implemented as a single element of a simplified retrofit, under certain conditions;
- Accord de principe (in-principle) must be obtained before work begins;
- Specific glazing parameters are required, as well as meeting the requirements regarding the thermal quality of the wall/roof or mechanical ventilation;
- the amount and possibility of obtaining support depend on current regulations and the individual project.
Collaboration Process
From the first measurement to the finished installation
- Consultation and Needs Assessment
We discuss the problems with your current windows and doors, the desired comfort, the home’s style, the schedule, and the budget. You can immediately send photos and approximate dimensions.
- Measurement and Solution Selection
We verify the openings, installation method, and connection to the façade and insulation. We select the material, glazing, hardware, color, threshold, and accessories.
- Offer and Funding Path
Before work begins, we organize the required parameters and documents and indicate which project elements may be eligible for funding.
- Installation and Acceptance
We remove the old joinery, install the new elements, perform sealing and adjustments, and upon completion, we provide information regarding use and project documentation.
