BSEN 1279

BSEN 1279 Product certification for Insulating Glass Units is the ultimate endorsement for our products, by considering performance (through testing) and [production (through quality management) we are able to demonstrate to specifiers and purchasers that our products not only meet the test requirements, but that every product produced will also meet the same high standards. In this way we offer confidence to the end-user that the installed window will meet these exacting standards.

To achieve and maintain this standard we have to submit products to an Exova/BMTrada UKAS accredited test laboratory (Chiltern Dynamics) who carry out stringent tests to ensure that the product meets or exceeds the required standard.

FIRAS is an accreditation scheme for the installers/applicators of passive fire protection products.

The scheme was developed to enable installers/applicators to gain the necessary level of skill through training. The quality of workmanship is monitored on an ongoing basis through site inspection of work in progress and audit checks of quality management systems.

This combination of site inspections, quality management system audits and training means it is possible to ensure that FIRAS accredited installers are competent to undertake the installation work for which they are accredited.

We are also part of the Fireglass double glazing scheme
