ENERGY STAR® – CANADA Fenestration products may comply for Canada’s Energy Star program based on these compliance paths: their total U-factor, their Energy Rating (ER), or both. The Energy Rating is based on a product’s overall performance based on three criteria: (1) solar heat gain, (2) U-factor, and (3) average air tightness. The higher the ER number, the better the product’s thermal performance. The U-factor and ER criteria for Canada is shown in the chart provided. For Kolbe products that qualify for Canada’s Energy Star Program, search their website at www.oee.nrcan.gc.ca/energystar.

Solar Heat Gain Coefficient (SHGC) is a measure of how much solar energy is passing through the unit’s glass. The lower a window or door unit’s SHGC, the less solar heat is transmitted into a room, thus allowing for lower cooling bills in hot climates. Visible Transmittance (VT) is a measure of the portion of visible light that passes through a window or door. The higher a window or door unit’s VT Total, the more visible light is transmitted into a room. This value is influenced by both the glass selection and by the ratio of glazing and frame area.
U-Factor refers to a measure of heat transfer through the window or door unit. A lower U-factor means less heat escapes during winter weather, thus reducing heating costs in cold climates. R-Value refers to resistance to heat flow. A high R-value indicates that a window or door has good heat insulating properties.
Kolbe demonstrates a commitment to providing accurate energy data by having products independently simulated, tested, inspected and listed in the NFRC certification program, and making that data available at kolbewindows.com and on window labels. Energy performance data and air, water, structural data is updated on a continuous basis. For the most current information, contact your local Kolbe dealer.
