Juignet

What Juignet does

Juignet SAS is a French custom aluminum and steel fabrication company founded in 1970 and headquartered in Les Sorinières, south of Nantes, in the Pays de la Loire region. The company designs, manufactures, and installs bespoke architectural products — aluminum windows, curtain walls, brise-soleil, sliding doors, metal doors, railings, stairs, and structural metalwork — in its own workshops for professionals, local authorities (collectivités), and individual consumers (particuliers). It operates as an approved TECHNAL aluminum partner (Aluminier agréé TECHNAL), giving it access to certified high-performance aluminum profile systems for thermal and acoustic applications.

The business model is sales-led and project-based, with direct sales of custom-engineered products plus professional installation by qualified in-house teams. Pricing is quote-based and not publicly disclosed, with each engagement specifying dimensions, materials, and installation scope. The company has recently introduced an after-sales service and maintenance offering (SAVM), creating a recurring post-installation revenue stream layered on top of the one-time fabrication and installation work. The commercial ecosystem is supported by partnerships with Saint-Gobain, AGC, Solarlux, Malerba, Sotraver, IDALU, La Toulousaine, and Froster, advertised on the company website.

The company employs 33 staff in a structure described as a "human-sized" enterprise (entreprise à taille humaine), serving a regional market in and around the Nantes metropolitan area. There is no public listing, no disclosed funding, no M&A activity, and no leadership transitions in the available data.

Direct peers

• Tryba: Major French window and door manufacturer/installer network with PVC, aluminum, and wood ranges. Comparable to Juignet on the custom fenestration installation side and on direct-to-consumer/particuliers go-to-market, but at significantly larger national-network scale.
• Profils Systèmes: French designer and manufacturer of aluminum profile systems for windows, doors, and façades. Comparable to Juignet as a domestic aluminum joinery/façade supplier serving similar building-envelope applications across France, though operating at a larger, brand-OWNER scale rather than as a regional fabricator.
• Sepalumic: French aluminum systems brand specializing in windows, sliding doors, and curtain walls. Directly comparable to Juignet's TECHNAL-based aluminum offering in terms of product scope (fenestration and façades) and target building projects, though Sepalumic sells profile systems and supports a national installer network.
• Installux (Alusud Concept): French aluminum systems manufacturer for windows, doors, and façades. Directly comparable to Juignet's TECHNAL-based product scope, with overlapping customer segments in commercial and residential fenestration, though again operating as a systems brand-owner rather than a regional fabricator.
• K-Line: French aluminum window and door specialist with a national network of installers and a dedicated commercial offer. Directly comparable to Juignet's menuiserie alu core business, including thermal/acoustic performance positioning and installer-partner model, but operating at substantially larger national scale.

Broad incumbents

• Aluprof: European aluminum systems manufacturer offering window, door, and façade profile systems. Comparable to Juignet's TECHNAL-anchored product set as an alternative premium aluminum systems supplier with broader geographic footprint and integrated roll-forming capability.
• Wicona (Hydro): European aluminum building envelope brand (part of Hydro Extrusion) covering windows, doors, and façades. Comparable alternative systems supplier to TECHNAL and a competitive context for Juignet's premium fenestration work, with broader European portfolio and scale.
• Schüco: German global leader in aluminum and steel building envelope systems (windows, doors, façades). Comparable as an alternative premium aluminum systems brand to TECHNAL, and therefore a competitive threat to TECHNAL-aligned fabricators like Juignet, with much broader geographic and product reach.
• Reynaers Aluminium: Belgian-headquartered European leader in aluminum solutions for windows, doors, curtain walls, and sliding systems. Comparable as an alternative systems brand to TECHNAL and therefore an indirect competitor to Juignet for premium aluminum fenestration, with broader portfolio and pan-European reach.
• Kawneer: Global aluminum architectural systems brand (part of Arconic) specializing in curtain walls, windows, and storefronts. Comparable to Juignet's aluminum curtain wall and façade offering as an alternative premium systems supplier with global scale and broad commercial building focus.
