Rachat de Diffuver

La famille Riou continue ses achats de miroiteries en France et son maillage du territoire français

Le premier groupe français de façonnage du verre plat RIOU Glass annonce le rachat du transformateur de verre plat Diffuver, domicilié à Marclopt dans le département de la Loire (42).

Après son entrée au capital du miroitier italien Cappelletti & Roleri en mai 2022, et du groupe belge Euroglas fin 2022, RIOU Glass signe une troisième acquisition dans le cadre de sa stratégie de développement RIOU GLASS VERRE 2025. Le premier transformateur indépendant de produits verriers en France vient de réaliser le rachat de la totalité des actions de l’entreprise Diffuver.

L’opération de croissance externe vise à consolider le maillage territorial de l’ETI en France. « Diffuver est un acteur reconnu en Auvergne-Rhône-Alpes avec lequel nous partageons un savoir-faire et les valeurs familiales communes, explique Christine Riou Feron, Présidente de RIOU Glass. Cette acquisition nous permet de parfaire notre maillage territorial déjà composé de 16 sites industriels en France. » Sans compter les sites dans les DOM TOM

Outre l’ancrage géographique, l’acquisition de Diffuver va également permettre de renforcer l’expertise de RIOU Glass dans la réalisation de vitrages de très grandes dimensions pour le marché de la façade, spécialité de Diffuver. Le rachat est enfin un moyen pour le groupe normand de déployer l’ensemble de sa gamme de solutions de vitrage sur le territoire. Une gamme qui s’étend du double au triple-vitrage à très hautes performances à des produits plus techniques et design (vitrages décoratifs pour les portes d’entrée, crédences de cuisine, cloisons…).

Philippe Melon continuera d’accompagner le développement de Diffuver avec à ses côtés Rémi Maximin, directeur du site de Marclopt, et les 40 collaborateurs que compte l’entreprise. « Ambition, passion et esprit de famille sont les valeurs que nous partageons avec le groupe RIOU Glass. Nous mettrons tout en oeuvre pour satisfaire leurs attentes et ainsi à travers eux, continuer cette belle aventure dans le monde du verre » conclut le fondateur de Diffuver.

As we were convinced, glass has experienced strong growth in applications for the interior, such as stairs, floor tiles, shower screens or kitchen splashbacks.

What ambition for the future?

The aim would be to work together to better meet the demands and heavy fund buying equipment investments.

Fenzi invests in digital processing machines

The Fenzi Partecipazioni holding company has decided to invest in digital glass processing technologies by buying into the capital of Tecglass, the Spanish producer of very high-tech digital glass printing machinery and components. This strengthens the working partnership of the two leading companies, which have already been working together for some time, and demonstrates the interest of Fenzi in innovations applied to glass while significantly increasing the growth potential of Tecglass on the international marketplace.

Established in 2002 by a group of experts who had a good deal of experience and know-how in this industrial sector, Tecglass has recently studied, developed and produced a range of digital printing machinery specifically for the glass industry. The technology takes the place of traditional decorating methods and offers a simple, efficient tool for applying graphic motifs and photographs directly on glass: ceramic inks can be used on glass for indoor or outdoor use, on sheets of any size (from a minimum of 380×380 mm. to a maximum of 3,300×18,000 mm), with a solution for any type of sector and application.

The sophisticated Tecglass technology fits in perfectly with Fenzi’s strategic vision and natural propensity for innovation which, a company whose financial strength, managerial skills and international sales network, can make the most of the considerable opportunities offered by what is a currently very promising market.

Companies and experts having an interest in this particular glass processing method will now have a new mix of services and products that meet the needs of designers, architects and developers both in terms of aesthetic results and manufacturing capability: Tecglass digital technology is now closer to glass processing companies worldwide and can count on the professionalism and solidity that have set the Fenzi Group apart for more than 75 years.
