Sika’s Sarnafil® AT Successfully Recertified and Sarnafil AT E Achieves First Cradle to Cradle Certification.
Cradle-to-Cradle Silver Distinction for Sarnafil AT® and Sarnafil® AT E
Sika is proud to announce that Sarnafil AT® has been successfully recertified under the Cradle to Cradle Certified™ (C2C) program, while Sarnafil® AT E, designed to meet higher fire requirements, has received its first C2C certification. Notably, Sarnafil® AT remains the first and only thermoplastic roofing membrane on the market to achieve Cradle to Cradle Certification™, reinforcing Sika’s leadership in sustainable building solutions.
As part of the certification process, Sika has also published a Material Health Certificate for both Sarnafil® AT and AT E. This certificate addresses the increasing demand from industries and consumers for transparency regarding the chemicals used in product supply chains and for the reduction of substances of concern.
Advancing Sustainability: Upgrading to the Latest C2C Standard
In 2023, the Cradle-to-Cradle Products Innovation Institute introduced a new, more rigorous product standard version (v4/4.1). During this certification cycle, Sika successfully upgraded four out of five certification categories to this latest standard—an achievement that underscores our commitment to continuous improvement.
Understanding Cradle-to-Cradle (C2C) Certification
The Cradle to Cradle Certified™ program is a globally recognized standard for product circularity and sustainable innovation. To achieve certification, products must meet requirements across five key sustainability categories: Material Health, Product Circularity, Clean Air & Climate Protection, Water & Soil Stewardship, Social Fairness. Certification levels range from Bronze to Platinum, reflecting the product’s performance in each category.
Growing Industry Relevance of C2C Certification
The adoption of Cradle-to-Cradle principles marks a significant step forward for Sika and the broader construction industry. Sustainability is no longer an emerging trend—it is a fundamental requirement for business success. By integrating the C2C framework into its product development strategy, Sika has reinforced its position as a pioneer in sustainable building materials and a trusted partner in the transition to a circular economy.
