IGMA Certification
The world’s leading organization on the engineering and manufacturing of insulating glass

Why do insulating glass manufacturers certify their products?
As a general statement, irrespective of industry affiliation, manufacturers who certify their products demonstrate commitment to their customers and their products. Certification provides assurance to customers, whether they are window and door manufacturers, building code officials, architects and specifiers or home buyers, that the insulating glass unit (IGU) product they are buying is designed to meet or exceed the applicable code or standard.

As more and more states/provinces are adopting the new energy codes there is an increased demand for thermal performance certification. Hand in hand with that is longevity. That is what IG certification is all about—testing the durability of the edge seal system.
