Leading the way in sustainable roofing: Anthéa and RENOLIT ALKORPLAN roofing products, a story of joint pursuit of excellence
RENOLIT ALKORPLAN roofing products supports the expansion of Anthéa with the construction of its new Gardanne headquarters. Designed to house also the new Anthéa Energie and Anthéa Entretien divisions, the project utilises RENOLIT ALKORPLAN Smart and Solar membranes to comply with the stringent environmental criteria of the BDM Silver label, strengthening a twenty-three-year partnership dedicated to solar innovation and roof waterproofing.
Sant Celoni – February 2026 – RENOLIT ALKORPLAN roofing products is proud to announce its contribution in the construction of the new headquarters for Anthéa, a French specialist in roofing, cladding, waterproofing, smoke evacuation, and photovoltaics.
Located in Gardanne on a historic former coal mining site, the project represents a benchmark for sustainable industrial design. To comply with the rigorous BDM (Bâtiments Durables Méditerranéens) Silver level certification required for the site, the facility integrates low-carbon steel and a high-performance roofing system using RENOLIT ALKORPLAN Smart and Solar membranes.
From coal mines to sustainable innovation: the evolution of the Gardanne site
Founded in September 2003, Anthéa is a specialist in roofing, cladding, waterproofing, smoke evacuation, and photovoltaics. A member of the Fédération Française du Bâtiment 13 (FFB13) and Qualibat waterproofing certified, the company has built its success on technical excellence and long-term professional relationships.
Central to this journey is a twenty-three-year partnership with RENOLIT ALKORPLAN roofing products, a collaboration that has been a cornerstone of the business since its inception.
The company was already established on this historic former coal mining site in Gardanne, where a decade ago it had already installed RENOLIT ALKORPLAN systems on several existing buildings.
When the opportunity arose to acquire the land, Giordanengo chose to establish a permanent base to support the group’s expansion and house its new divisions: Anthéa Energie, focused on photovoltaic installations, and Anthéa Entretien, dedicated to roof maintenance.
However, the land acquisition was strictly conditional on meeting the stringent environmental criteria of the BDM Silver label, a certification that evaluates the environmental performance of buildings in the Mediterranean climate, ensuring they respect the local ecosystem through bioclimatic design and sustainable material use.
Meeting BDM Silver standards with RENOLIT ALKORPLAN’s high-reflectance and solar solutions
To meet the stringent BDM Silver requirements, the project utilises RENOLIT ALKORPLAN Smart, a cool-roof membrane designed for high solar reflectance. This solution features specialised pigments that reflect solar radiation, significantly reducing building overheating and the energy required for cooling, a vital benefit in the Mediterranean climate. Its reduced thickness and weight also contribute to a lower carbon footprint by reducing emissions during transport.
In addition to this, Anthéa employed the RENOLIT ALKORPLAN Solar system to support the photovoltaic panels, ensuring a seamless integration of renewable energy. This carrier system is hot air welded to the membrane, ensuring total watertightness without the need for ballast or piercing the roof structure.
“The choice of RENOLIT ALKORPLAN and the Solar system was natural for us, as we have been collaborating for over 20 years. What I appreciate about RENOLIT ALKORPLAN and PVC is that it is one of the easiest synthetic solutions to weld and install”, says Giordanengo.
