The highest quality solar
Polar windows’ Energy Rating is +43. Polar doors have a solid R15 polyurathane core. This advanced window and door technology will bring you energy savings for decades.
Energy Rating (ER) is a benchmark rating system adopted as part of the CSA A440.2 Standard of Canadian Build Code. ER represents a single modeled performance rating for a window, expressed in Watts per square meter (W/m2), based on standard window sizes and categories and average Canadian climactic conditions. ER takes into account a window’s capacity to emit solar heat, its insulating capacity or R-Value, and its ability to resist air leakage.
ER ratings range from 0 to 50. A rating of 0 indicates neutral energy consumption, where a window contributes as much solar heat as it loses over a full heating season. A window with a positive ER measurement saves energy, while a window with a negative ER loses energy.
