We are proud to have been awarded the prestigious Cradle to Cradle (C2C) Certified® Full Scope Bronze certificate, for five of our aluminium window systems - Alitherm 300, 400, 600 and Heritage, and Visotherm.

Certification provides assurance to customers that the materials we use are non-toxic, responsibly sourced, and designed for circularity - reducing waste and environmental impact. It also reflects our commitment to sustainability, innovation, and transparency, and to supporting compliance with green building standards, and the circular economy.

What is C2C certification?

Cradle to Cradle® Certified is a globally recognised standard for environmentally and socially sustainable products. Developed by the Cradle to Cradle Products Innovation Institute, it helps companies across a wide range of industries to design and manufacture products that are safe, circular, and sustainable. Certification independently verifies a product’s performance across five key areas:

Material Health – ensures materials are non-toxic and safe throughout their life cycle

Product Circularity – how products can be disassembled, reused and recycled

Clean Air & Climate Protection – the use of renewable energy and climate protection

Water & Soil Stewardship – responsible water use and management

Social Fairness – commitment to social responsibility, including ethical supply chains

For products like ours, the certification process follows the Technical Cycle, focusing on reuse and recycling to support a circular economy.

How does C2C Certified® differ from other environmental standards?

C2C Certified® looks at much more than reducing harm, aiming to create positive impacts by eliminating waste and promoting safe material reuse, where materials are continuously recycled, safely.

Unlike other environmental standards which tend to assess buildings or organisations, C2C Certified® focuses on individual products, evaluating materials, manufacturing processes, and end-of-life potential.

Note: Certification does not include glass, handles, doors, and hinges.

This means these products are designed with life cycle thinking in mind, and meet strict, science-based requirements for Material Health, Product Circularity, Clean Air & Climate Protection, Water & Soil Stewardship, and Social Fairness.

Certification reflects Smart’s commitment to sustainability, innovation, and transparency, and to supporting compliance with green building standards, and the circular economy.

What does it mean for our customers?

Confirming the company’s commitment to sustainability, certification means that customers can trust that the certified products are safe and non-toxic, sustainable and ethically sourced and manufactured.

Customers can also trust that the products support climate protection, water stewardship, and social fairness, enabling them to make informed, value-driven decisions that contribute to a healthier plant.

Architects can also confidently specify materials that align with green building standards like BREEM, LEED and WELL, and which support design integrity and environmental responsibility.

In turn, building owners will benefit from:

Healthier environments

Reduced environmental impact

Enhanced asset value

Support for ESG goals and long-term efficiency
