The IGQA mark has been developed to enable insulating glass unit manufacturers who comply to demonstrate that their i.g. units are manufactured to a high quality standard. The mark is awarded to those who have undergone and passed stringent auditing procedures specifically related to the quality of the insulated glass unit so that customers can confidently order i.g. units safely in the knowledge that standard levels of manufacturing quality have been surpassed.

The auditing scheme used has been developed following 40 years experience of working in the insulating glass unit industry, both in the UK and across Europe. The experience gained over this period has enabled the author to develop and offer the best possible system to ensure product quality is provided and maintained.
