Preface
This is the fifth edition of CSA A440.2/A440.3, Fenestration energy performance/User guide to CSA A440.2-09, Fenestration energy performance. It supersedes the previous editions published in 2004, 1998, 1993, and 1991 under the title Energy performance of windows and other fenestration systems (and associated user guides). This edition incorporates CSA A453-95, Energy Performance Evaluation of Swinging Doors, which is considered superseded by this Standard.
