Spurgin confirms its multifaceted dynamism

Spurgin is recognized and appreciated by all construction professionals for its spirit of innovation, offers ensuring perfect adaptation to each configuration, ease of implementation of its products, systematic attention to safety and technical performance. Spurgin has been combining its offers for several years with a significantly reduced environmental impact. After the inauguration in 2024 of its new wood concrete wall production unit in Mignières (13 million euros of investment), Spurgin confirms, for 2025, a strong dynamic both commercially and industrially without forgetting its credo for innovation and investments aimed at democratizing low-carbon prefabricated solutions.

Spurgin between growth, investments and innovation

Pierre Bollard, CEO of Spurgin, is pleased with the 2025 momentum, despite a highly disrupted construction sector. Indeed, while Spurgin reports a 6% increase in production and sales figures for its Precast Wall business, its Isopré division is growing by 28%. This trend perfectly illustrates the growing interest among construction professionals in low-carbon, all-in-one solutions implemented in the infrastructure and ground floor of multi-family buildings, from schools and high schools to public access buildings and large housing complexes.

Pierre Bollard points out that Spurgin is the only French manufacturer capable of delivering to construction sites in less than three weeks and at a high production rate (from the date of receipt of the plans), and also specifies that "the wood-concrete plant in Mignières will have produced, by the end of September, just over 20.000 m³² of walls.” He continued: “The wood-concrete activity in Mignières is off to a slow start and has benefited from projects completed by major companies such as Bouygues/Eiffage/GCC/Léon Grosse. Furthermore, projects like the Clos Saint Joseph real estate development in Saint Pryvé-Saint-Mesmin, near Orléans, built using wood-concrete by SABARD Bâtiment, have also been delivered. In this context, we are also pleased that regional developers are attracted to wood-concrete, its ease of implementation, its environmental benefits, and the summer comfort it provides to future residents.” He concluded: “Our specification team is providing valuable support to developers, architects, and engineering firms. 2026 should be a significant year and will see a sharp increase in the production of wood-concrete walls.”

Furthermore, to support the development of its short-circuit offer of wood-concrete load-bearing walls, Spurgin announces an investment dedicated to the construction of a new wood-concrete plant on its Blyes site in the AURA region, for the end of 2026.

Spurgin and Activ'Home: a perfect complement to industrially develop the wood-straw solution

True to its motto, "the right wall in the right place," Spurgin enhanced its low-carbon offerings at the end of 2024 with the acquisition of Activ'Home. Founded in 2011, this company notably won the Jury's Choice Award at Energy Sprong 2021 and was a winner of the 2020 National Innovation Competition for the Grand Investment Plan (the only winner in the Building Environmental Performance category to have proposed bio-based materials).

As a reminder, Activ'Home is the exclusive distributor of wood-straw construction modules produced using a short supply chain, according to the patented ECOSTRAUV process.^®This timber-straw construction module serves as both a frame and insulation for walls, partitions, floors (upper or lower), and roof elements. These modules, compliant with RE2020 regulations and eligible for E+C- certification, are used in load-bearing walls up to two stories (R+2). Furthermore, these modules are suitable for the construction of passive and/or net-zero energy buildings. The timber-straw frame range allows for an R-value of 5 to 7,5 m.².K/W while offering strong economic performance. Since its inception, Activ'Home has demonstrated the technical and environmental relevance of its offering, combining bio-based materials, carbon storage, and exceptional thermal lag. While Activ'Home solutions deliver exemplary performance in new construction, they are also ideal for renovation projects, effectively maximizing the value of existing building envelopes.

For Pierre Bollard:“We are combining our industrial expertise with Activ'Home's pioneering vision to amplify the reach of a bio-based, innovative construction solution perfectly suited to climate challenges: the timber-frame wall with straw infill. The acquisition of Activ'Home is more than just an industrial operation; it represents a further commitment to our environmental approach to address the climate disruptions that lie ahead.”

Until now, its production has been based on a small-scale, artisanal approach, limited in volume. Tomorrow, with Spurgin's technical expertise and financial support, its production will move to an industrial scale. Indeed, Spurgin announces that, starting in the first half of 2026, a €4 million investment will enable the new Activ'Home production site in Reugny to manufacture approximately 60.000 m² of walls and facades annually.

Activ'Home: combining inertia, phase shift and carbon storage by moving from the artisanal stage to the industrial tool

Spurgin advocates for the explicit and binding consideration of phase shift (or an equivalent criterion) in upcoming revisions of the energy efficiency (RE) calculations, either through a minimum phase shift threshold for certain walls or through a regulatory bonus for structural walls with high phase shift. Along the same lines, the company calls for an acceleration of the schedule aimed at lowering the thermal conductivity (Ic) thresholds (or the introduction of more ambitious intermediate thresholds). Finally, the last key benefit for Spurgin is the summer comfort generated by intelligent design. Effective design must indeed consider the right materials in the right places within the building to optimize the building envelope, protecting its occupants from heat and cold for many years.

Pierre Bollard to elaborate “We are living through a pivotal moment. The building sector is on the front line in the face of climate change. The extreme heat waves we experienced twenty years ago in India or the Middle East are becoming a realistic prospect for Paris and all our European metropolises. Scientists are warning us: 50 degrees Celsius is not a simulation but a deadline. In this context, the RE2020 regulation marks progress: it introduces carbon, energy, and summer comfort. But it remains gradual, sometimes too lenient. It doesn't sufficiently value one of the essential levers of summer comfort: thermal lag, that is, the ability to delay the entry of heat into buildings. Yet, this parameter will determine the quality of life of residents in their homes and offices in the future. It will transform an uninhabitable building into a pleasant one during weeks of heatwaves. I firmly believe that sustainable buildings will not be made with a single material, but with the right material in the right place within the building.” We work with designers and developers to highlight the value of our solutions and the complementary nature of our products in their future buildings, in order to meet their technical and environmental needs. Our design offices ensure the long-term viability of the choices made and are increasingly focused on providing precise support for implementation with our clients. Today, with the acquisition of Activ'Home, we are taking another step forward.

Pierre Bollard to continue “We are taking responsibility in the face of climate change. We are investing in a bio-based, local, renewable building solution that protects occupants and reduces the sector's carbon footprint. Because we know that at 50 degrees Celsius, a poorly designed building is no longer habitable. Because we know that there will be no comfortable future without thermal inertia and phase shift. And because we know that construction must be part of the solution, not the problem, we are now making Activ'Home a complementary industrial force serving users. This is a significant shift. We will supply both large-scale public and private projects on a just-in-time basis, with customized elements that can incorporate various options, such as joinery. Our ambition is not to pit concrete against wood, thermal inertia against phase shift. On the contrary, it is to combine them intelligently.” A high-performance building is one that combines several materials, depending on its orientation, use, and needs. Our teams know how to guide designers in choosing the right wall for the right place in the building, in order to guarantee carbon performance, summer comfort, and economic efficiency.

Technical and environmental qualities of Activ'Home products

Straw, surely the cheapest insulation on the market and available in large quantities.

• Carbon performance (Ic Construction): thanks to wood and straw, Activ'Home walls store more carbon than they emit over their life cycle. This is a direct response to the current and future requirements of RE2020 and certainly far beyond.
• Exceptional thermal lag: straw offers a significantly longer thermal lag than conventional insulation. In other words, Activ'Home walls retain outside heat for several hours before it penetrates the interior. This is an obvious solution for summer comfort.
• Adaptability in new construction and renovation: In new construction, they enable exemplary performance. In renovation, they provide an immediate solution for existing buildings whose building envelope is not, or has never been, energy-efficient. Many of these buildings in France are vulnerable to the heat waves expected in the future.
