Help! There's a blizzard of groups that test window performance.
What do I look for?
Many groups now assess performance and set standards in order to assist consumers and the industry. But you need a program to know the players.
Canadian General Standards Board (CGSB) has an insulated glass unit (IGU) standard assessing durability of window and door sealed units.
Canadian Standards Association (CSA) has a voluntary certification program. Independent auditors determine whether windows comply with CSA-A440, The CSA constantly monitors and certifies that North Star's manufacturing and testing process meet or exceed CSA standards. All North Star products are CSA certified. Please contact a North Star dealer for complete details about the certification process and the performance testing results on all North Star windows.
Insulating Glass Manufacturers Alliance (IGMA) is a North American association of insulating glass manufacturers, suppliers of component materials and other industry professionals dedicated to upgrading product performance by promoting awareness of technological developments in the industry.
