Grosfillex Fenêtres

What Grosfillex Fenêtres does

Grosfillex Fenêtres (legal entity: Grosfillex SAS) is a French manufacturer of PVC and aluminum fenestration products headquartered in Arbent, Ain (eastern France), founded in 1980 and operating for over 40 years. The company designs, manufactures, and sells windows, French doors, sliding glass bays, entry doors (PVC, aluminum, wood, and armored), roller and swing shutters, garage doors, bioclimatic pergolas, carports, fencing, and railings under the Alta (PVC), Aluméa (aluminum), and Bhautika (entry doors) sub-brands, with a 20-year warranty on PVC products and NF CSTB plus CEKAL certifications. Underlying technology focuses on thermal and acoustic performance: low-emissivity double and triple glazing with argon filling, Warm Edge spacers, multi-chamber PVC profiles, thermal-break aluminum frames, and decorative plaxage film coatings for aesthetic and weather protection.

The business model combines manufacturing with an exclusive concessionnaire distribution and installation network of approximately 110 stores across France, staffed by 800+ technical sales advisors and installers. Revenue is generated through wholesale supply of made-to-measure products to the captive dealer network, with installation services performed by the concessionaires themselves. Pricing is quote-based with no public list; the dealer sales workflow integrates French energy-renovation financing — MaPrimeRénov' subsidies, CEE bonuses, eco-PTZ loans, and reduced 5.5% VAT — to lower buyer out-of-pocket cost. The company reports 60,000+ door and window installations per year and positions itself as a leading French PVC window brand. End customers are predominantly individual residential homeowners undertaking renovation or new construction, with property managers and landlords as a secondary segment. The geographic footprint is exclusively France; no international operations, subsidiaries, parent company, or external investment are disclosed.

Direct peers

• K-Line: K-Line is a French aluminum sliding window and door specialist with comparable product positioning in the premium aluminum fenestration segment (directly comparable to Grosfillex's Aluméa line) and a focus on residential and light commercial customers in France.
• K par K: K par K is the closest direct competitor: a French specialist in made-to-measure windows, doors, and home closures distributed through a similar nationwide network of franchise/concessionnaire stores. Same product categories (PVC, aluminum, mixed), same GTM (dealer network with measurement and installation), same target customer (French residential renovation).
• Atlantem: Atlantem is a French industrial group manufacturing PVC and aluminum windows, doors, and shutters for the residential market, with comparable product range and direct competition in the same French fenestration category.
• Janneau: Janneau is a French window manufacturer with a long history in the category, offering a comparable multi-material range (PVC, aluminum, wood, mixed) and operating through a similar installer/dealer network for residential renovation.
• Tryba: Tryba is a leading French window and door manufacturer with a similar concessionnaire/distributor network model, comparable multi-material product range (PVC, aluminum, wood), and overlapping focus on residential energy renovation. Direct head-to-head competition in the same customer segment.
• Lorillard: Lorillard is a long-established French window and door manufacturer (founded 1936) operating in the same fenestration category with comparable PVC and aluminum product lines and a similar dealer-based distribution approach for residential and small commercial projects.

Broad incumbents

• Saint-Gobain: Saint-Gobain is a global building materials leader and parent of Lapeyre, with extensive fenestration and habitat products business. It is a broad incumbent whose scale, distribution, and brand create competitive pressure in the French window/door market, particularly on commercial and large residential projects.
• Lapeyre: Lapeyre is a major French home improvement brand (part of the Saint-Gobain group) offering windows, doors, staircases, and bathroom/kitchen products through its own retail network. It is a broader incumbent in fenestration with wider product breadth, competing for the same residential renovation customer.

Others

• Profine: Profine is a major European PVC and aluminum profile systems manufacturer (KBE, Kömmerling, Trocal brands) supplying window fabricators across Europe. Like Veka, it is an upstream supplier whose technical innovations and pricing influence the competitive position of French window manufacturers.
• Veka: Veka is one of the world's largest PVC profile systems suppliers, providing the extruded profiles that manufacturers like Grosfillex use to fabricate their PVC windows. It is an ecosystem supplier rather than a direct competitor, but its product roadmap and pricing materially affect the cost base of Grosfillex's PVC range.
