In a context where quality, safety and compliance become decisive factors in the choice of building materials, insulating glass must comply with strict European standards. Two of the most relevant certifications in this field are the CE mark and ISO 9001 certification. They ensure not only compliance with legislation, but also confidence in the durability and performance of the product.

What is the CE mark?

CE marking is an official statement by which the manufacturer guarantees that its product complies with all applicable requirements of European Union legislation. For insulating glass, this marking is mandatory and indicates that the product has been tested according to the European standard EN 1279.

For manufacturers, the CE marking implies:

• Implementation of a permanent production control (FPC – Factory Production Control).

• Making of initial performance tests (ITT – Initial Type Testing).

• Traceability and proper labelling.

For customers (architects, developers, public institutions), the CE mark means that the product is safe, tested and according to the minimum mandatory standards for marketing in the EU.

What tests must a thermal insulating glass pass to be CE compliant?

To obtain the CE marking according to the standard EN 1279, the insulating glass must pass a series of tests, including:

• Gas tightness – verification of inert gas losses between the glass sheets.

• Thermal transmittance (Ug) – measuring the ability of the glass to thermally insulate.

• Durability – testing the behavior in extreme climatic conditions.

• Vapor permeability – test to prevent condensation inside the unit.

• Mechanical strength and integrity of the sealed edge.

These tests are carried out in authorized laboratories and are essential for validating the quality of the product before it is marketed.

The role of ISO 9001 certification in quality control

ISO 9001 is an international standard regarding quality management system. In the glass processing and insulating glass manufacturing industry, this certification reflects the manufacturer's commitment to:

• Well documented and monitored internal processes.

• Continuous improvement of product quality.

• Control of risks and non-conformities.

• Increasing customer satisfaction.

An ISO 9001 certified manufacturer ensures that each production unit follows strict quality and traceability rules, reducing the risk of defects or batch-to-batch variation.

Why are these certifications important in large or public projects?

In the projects of public buildings, especially those financed from European funds, compliance EC norms and of ISO quality is an essential requirement. Authorities require compliance documents for:

• Safety in use (schools, hospitals, offices).

• Energy efficiency according to EU directives.

• Long-term durability and low maintenance.

• Traceability in case of audit or complaint.

Thus, the choice of a CE and ISO 9001 certified supplier becomes an indispensable condition for eligibility in tenders and the guarantee of a successful project.

VALRAS is firmly committed to complying with all European requirements regarding the quality and conformity of the insulating glass. The factory owns:

• CE mark for all ranges of thermal insulating glass, with tests carried out according to EN 1279.

• ISO 9001 certification, reflecting a robust quality management system.

• Strict control over the production process, from raw material selection to final delivery.

By complying with these standards, VALRAS offers not only compliant products, but also confidence – the essential element in any quality construction project.

In a market where quality makes the difference, the CE mark and ISO 9001 certification become indispensable landmarks for any beneficiary. Choosing a manufacturer like VALRAS, which strictly adheres to these standards, is a sure step towards efficiency, durability and total compliance in modern construction.
