Siderise Insulation achieves BES 6001 responsible sourcing certification
16 September 2025
SIDERISE INSULATION has achieved certification to the latest version of the BES 6001 standard for all of its stone wool passive fire protection and acoustic products manufactured at the company’s Maesteg factory in South Wales. This latest achievement for the business evidences an ongoing commitment to achieving the highest sustainability standards.

Developed by UK-based research organisation the Building Research Establishment, the BES 6001 framework standard requires construction product manufacturers to evidence that their products are made from responsibly sourced materials. The independent assessment process looks at every product stage, from raw material extraction through to processing and point of sale.
Businesses are scored against a range of criteria, including supply chain management, management systems and social and environmental factors such as biodiversity and site stewardship.
Siderise was awarded a ‘Good’ rating in the wake of a comprehensive review of its processes and procedures around matters such as procurement practices, the supply chain, transport impacts, lifecycle assessment and engagement with local communities. The company received full marks for its environmental and quality management systems in the supply chain, the responsible sourcing policy and operational management of responsible sourcing.
Developing supply chain controls
Sera Turkoglu, sustainability manager for the Siderise Group, explained: “Many of our standard practices already aligned with BES 6001 principles. However, as part of our Environmental, Social and Governance strategy, we were keen to enhance and formalise our internal processes, develop our supply chain controls and confirm that our practices meet the stringent requirements.”
Turkoglu continued: “For our first assessment, we were pleased to achieve a ‘Good’ rating as this provides a solid benchmark for us to raise that rating in subsequent audits and reaffirms our position as a trusted and forward-thinking leader in our industry.”
Important milestone
Gary Marshall, quality manager at the Siderise Group, added: “Achieving BES 6001 certification marks an important milestone in our ongoing commitment to sustainability, ethical sourcing and responsible supply chain management. It reflects the hard work and dedication of our entire team and demonstrates how we are aligned with industry Best Practice for environmental stewardship and social responsibility, thus making us better equipped to support our customers in meeting their own sustainability goals.”
BES 6001 certification is recognised across the globe as demonstrating responsible and sustainable procurement practices in addition to reduced supply chain risk. Products certified to it can support specifiers to secure additional credits under sustainable building certification standards, such as BREEAM, LEED and DGNB.
