Confirming IGU compliance

Andy Jones

In response to the recent news that the Office for Product Safety and Standards (OPSS) is turning its attention to IGU manufacturers and glass unit performance, Andy Jones has launched a product testing and compliance support service GlassCheck UK to help IGU manufacturers evidence compliance with BS EN 1279.

The new service will allow up to 50 units to be tested for argon gas concentration per visit using state of the art, non-destructive SparkLike Laser testing technology. All test data is appropriately recorded so that companies can demonstrate compliance, ensure up-to-date product labelling and protect their business from potential future liability.

Andy Jones, director of GlassCheck UK, says: “The Office for Product Safety and Standards (OPSS) has set-out their stall with their 2026 Heat Soaked Thermally Toughened Glass Sector Regulatory Report. They visited every heat soaked toughened glass manufacturer and though the product was, in the main, up-to-scratch, most businesses were found to be non-compliant due to insufficient paper-trails and test data evidence to support their declaration of performance (DoP) certificates.

“The result was that the OPSS issued nine prohibition notices, stopping these businesses from supplying products, and 25 companies were issued warnings requiring them to address their non-compliance issues. Now, the OPSS is turning its attention to IGUs and compliance with BS EN 1279.

“The OPSS has the power and the resources to make unannounced visits to check compliance, so the million-dollar question for IGU manufacturers is: does every IGU that leaves your factory receive the same care and attention as your annual test units? If the answer is no, you could be putting your business at risk.”

Glass Check UK’s test services also include non-destructive tests on installed units in buildings, argon gas concentration, dew point and glass emissivity tests to determine the real-world performance of installed IGUs.

“GlassCheck UK has been created to support the industry, helping IGU manufacturers to prove and document that their units meet the requirements of BS EN 1279 and support the commercial sector with certainty that their windows are maintaining high performance throughout their life cycle.

“Our goals are twofold: protect IGU manufacturing businesses from the ever-increasing regulatory scrutiny and ensure high-quality insulated glass units are performing as they should be, to improve efficiency and help us meet the government’s Net Zero targets.”
