Made-to-Measure Crittall Screens and Conservatories in Luxembourg — From the Parisian Atelier to the Winter Garden
Whether it is a Crittall-style screen in the Parisian atelier tradition or a made-to-measure wrought-iron greenhouse, Vitralux knows how to marry metal and glass into light-filled additions that change a living space completely.

Glass and metal: a combination that never runs out
The Crittall screen and the greenhouse share the same architectural DNA: a grid of metal bars framing panes of glass. That way of building was born in the great Victorian glasshouses of the nineteenth century and in the artists' ateliers of Paris, and it is now one of the most sought-after looks in contemporary architecture.
Vitralux covers two broad families: Crittall-style screens for dividing living and working spaces without cutting out the light — including with an integrated Crittall-style door —, and greenhouses & conservatories, to add a bright room to a house that works in every season. Both are built on the Laruche Paris system, the French benchmark for this kind of work.
Every project is made to measure: exact dimensions, orientation, number of panes, type of opening leaf and profile finish. Vitralux takes on the whole project, from design through to final fitting.
Two families of work
From an atelier-style room divider to a glazed extension that opens onto the garden: two worlds, one craft in glass and metal.

Crittall-style screen, industrial look
The Crittall-style screen in the Parisian atelier tradition has been the most fashionable piece of interior architecture of recent years. Bars in steel or matt black aluminium divide a wall of glass into a grid of small panes: the space is defined without being closed off, and the light keeps flowing.
- System: Laruche Paris — steel or powder-coated aluminium profiles
- Finishes: matt black (standard), white, anthracite, RAL on request
- Glass: clear, satin, tinted, with or without glazing bars
- Configurations: fixed, or with an integrated hinged or sliding door
- Applications: dividing a kitchen from a living room, a study from a lounge, a studio

Period-style greenhouse and conservatory
The architect-designed greenhouse and the period-style conservatory are the ideal way to extend a Luxembourg house: an extra room full of light, opening onto the garden, usable all year round. Laruche Paris greenhouses combine the look of the great Victorian glasshouses — curved ridge, slender profiles, small panes — with modern thermal performance.
- System: Laruche Paris — greenhouse and conservatory division
- Style: Victorian classic, contemporary linear or a mix of the two
- Structure: steel or powder-coated aluminium
- Roof: mono-pitch, dual-pitch or mansard, fully glazed
- Glass: laminated safety, thermal insulating, solar control
Greenhouse, conservatory: what about planning permission?
In Luxembourg, adding a greenhouse or a conservatory to a house can require planning permission above a certain floor area — the threshold varies from commune to commune. Vitralux points you to the procedure that applies as soon as we start looking at your project.
Laruche Paris: the French benchmark in glass and metal
Laruche Paris has specialised in internal Crittall-style screen systems and steel-and-glass structures for several decades. Its range covers industrial-look internal screens as readily as period-inspired greenhouses and conservatories: metal profiles designed to be strong, slender and elegant all at once.

Frequently asked questions about Crittall screens and conservatories
An internal Crittall screen is a structure of glass and metal used inside a building to separate two spaces: it has no particular thermal role, since it stands between two heated volumes. A greenhouse or a conservatory is an external addition attached to the house: it separates the inside from the outdoor climate, so it has to perform well enough thermally to be livable in winter.
In Luxembourg, planning rules are set by each commune: above a certain floor area — and the threshold varies from commune to commune — an application for planning permission is generally needed for a greenhouse or a conservatory attached to an existing house. Vitralux points its clients to the procedure that applies in their commune while the project is still being worked out.
Yes. Laruche Paris systems include dedicated seals at every glass-to-metal junction and drainage profiles overhead to carry rainwater away. The structures are designed to stand up to European weather, heavy rain and snow included.
Yes, a conservatory can become a proper living room. Dedicated heating is generally needed for year-round use, and the glass build-up is specified according to the configuration and the intended use. Vitralux works out the right solution with you at the design stage.
It is possible subject to survey: a conservatory on a terrace calls for a check on the load-bearing capacity of the floor slab and, in some cases, coordination with a structural engineer. Vitralux assesses the feasibility during the technical visit and adapts the project to the existing building.
A contemporary greenhouse takes a linear, minimalist line: slender profiles, large panes, a straight ridge. A period-style conservatory looks back to the Victorian glasshouses: more ornate profiles, a curved or pointed ridge, small panes of glass, a brick or stone base. Both are available in the Laruche Paris range. The choice comes down to the architectural style of the house and the client's own taste.
