For more than 45 years, ACTIS has been redefining the way buildings are insulated. Headquartered in France, the company has become Europe’s leading manufacturer of reflective insulation solutions, recognised for its innovation, industrial expertise and commitment to improving the energy performance of buildings. Today, ACTIS products are installed in hundreds of thousands of buildings across Europe, reflecting decades of innovation, quality and industrial expertise.
Today, ACTIS is led by the Thierry family, with Guillaume Thierry working alongside his father and brother to continue the long-term vision that has shaped the company since its creation. As an independent family-owned business, ACTIS has always favoured long-term investment over short-term decisions, continuously strengthening its industrial capabilities, developing new technologies and expanding into international markets.
What truly distinguishes ACTIS is its ability to control the entire value chain. Unlike many manufacturers, the company designs, develops and manufactures all of its insulation solutions in-house. From research and engineering to production, quality control and logistics, every stage is managed within its own facilities. This fully integrated approach gives ACTIS complete control over quality, performance and innovation while enabling rapid responses to evolving market needs and building regulations. This ability to invent, develop and manufacture its own technologies under one roof is one of the company’s greatest competitive advantages.
Innovation is deeply embedded in ACTIS’ DNA. Rather than following industry trends, the company has consistently challenged conventional approaches to insulation by developing proprietary and patented technologies that combine reflective insulation with advanced insulating materials. Innovation is not viewed as a department within ACTIS, but as a company-wide culture that drives every stage of product development. Every new solution is the result of extensive research, engineering, laboratory testing and continuous product development before reaching the market.
Research and development remain a cornerstone of the company’s strategy. ACTIS invests continuously in new products, manufacturing technologies and certification programmes to ensure its solutions meet—and often exceed—the highest technical and regulatory standards. This commitment to innovation has enabled the company to build a unique portfolio of high-performance insulation systems trusted by professionals across Europe.
Industrial excellence is equally central to ACTIS’ identity. Every product is designed and manufactured in France using advanced production technologies and rigorous quality processes. The company’s manufacturing facilities continue to benefit from significant investment, ensuring ACTIS remains at the forefront of industrial performance and product quality. Continuous investment in manufacturing equipment and industrial performance enables the company to deliver premium-quality products while maintaining the flexibility and responsiveness of an independent family business.
Today, ACTIS products are distributed throughout Europe and in a growing number of international markets. Working closely with distributors, contractors, architects and technical experts, the company continues to promote innovative insulation solutions that contribute to more energy-efficient and sustainable buildings worldwide.
Despite its position as the European leader in reflective insulation, ACTIS has retained the culture and values of a family business. Long-term thinking, entrepreneurial spirit, continuous improvement and close relationships with customers and partners remain at the heart of every strategic decision. These principles have enabled the company to combine technological leadership with the agility needed to anticipate the future of the construction industry.
ACTIS is also an active member of the Reflective Insulation Manufacturers Association International (RIMA). The company believes that collaboration between manufacturers, researchers and industry organisations is essential to advancing technical knowledge, encouraging innovation and strengthening the recognition of reflective insulation technologies around the world.
For the Thierry family, the mission remains unchanged: to continue investing in people, research, manufacturing and innovation while developing unique insulation technologies that contribute to a more sustainable built environment. After more than four decades of innovation, ACTIS continues to demonstrate that industrial excellence, family ownership and technological ambition can successfully shape the future of building insulation. https://www.actis-isolation.com/
