2026 ESG Report: How Stev is Reducing the Carbon Footprint of Mineral Wool.

Focusing on '2026 ESG Report: How Stev is Reducing the Carbon Footprint of Mineral Wool.', this article is organized in the order of 'problem identification—materials and construction—construction control—acceptance and maintenance', providing directly executable parameters, methods, and checklists, making it convenient for design, procurement, construction, and operation & maintenance teams to directly reference on-site management.

1. Basic Requirements for Incoming Inspection

When materials arrive on site, the brand, model, specifications, batch, and certificate of conformity should be checked, and appearance inspection and sampling re-inspection should be conducted according to the standards. Only when the incoming inspection and witnessed sampling records are complete can the material quality be traceable.

2. Inspection Items and Frequency

3. Witnessed Sampling and Re-inspection

Materials related to fire prevention and structural safety should undergo witnessed sampling as prescribed and be sent to qualified testing institutions for re-inspection. Test reports should correspond to the usage location and batch, avoiding one report covering multiple different products.

4. Data Archiving

• Establish a ledger of incoming materials and batch index.
• Keep certificates of conformity, test reports, and re-inspection records.
• Retain images of witnessed sampling and submission forms.
• Store non-conforming materials separately and handle their removal from site.

The key to standard compliance is evidence. The chain formed by incoming inspection, sampling, re-inspection, and archiving ensures that quality responsibilities are clear and traceable.
