When evaluating energy performance ratings for your doors and windows, in addition to adhering to Energy Star®’s standards, it is important to refer to the harmonized standard set by the North American Fenestration Standard (NAFS). The NAFS specification is more commonly known under the name of “structural performance tests.”
As well as evaluating air and water tightness, the NAFS standard evaluates a door or window’s resistance to natural elements such as strong winds.
In Canada, the standard’s minimum requirements are determined according to your region and its weather conditions.
Prior to purchase, it is important to confirm the minimum required Performance Grade (PG) for your region and the surroundings of your home (location, product height, type of land, etc.).
Easily get your minimum PG with the Fenestration Canada’s performance calculator.
