LoĒ-180ESC Glass for Canada
When the weather turns bitterly cold in Canada, Cardinal LoĒ-180ESC™ glass is like a warm welcome to your home.
LoĒ-180ESC is an update of our successful LoE-180 glass and is designed to help meet the new performance requirements for ENERGY STAR® Canada in 2020.
It keeps homes warmer and more comfortable by blocking heat loss to the outside and letting the sun’s heat stream in. With a glass U-Factor of just 0.26 and an SHGC of 0.71, LoĒ-180ESC is the ideal product for passive solar applications in Canada.
Glass Made for ENERGY STAR 2020 Requirements in Canada
ENERGY STAR version 5.0, issued by Natural Resources Canada (NrCan), went into effect on January 1, 2020. The improved energy efficiency requirements can be met with either a maximum U-Factor of 1.22 (W/m²·K) / 0.21 (BTU/hr·ft²·°F) or minimum Energy Rating (ER) of 34 for the window or door.
Meeting this low U-Factor would require a triple pane insulating glass unit. A dual pane option can meet the minimum 34 Energy Rating, requiring the window to balance a high solar heat gain coefficient (SHGC) with a low U-Factor.
To match the updated and expanded ENERGY STAR Canada guidelines, Cardinal CG has developed the LoE-180ESC coating. It’s engineered to help more windows and doors meet the new Energy Rating of 34 throughout Canada. LoE-180ESC is a 3rd surface coating for a dual pane unit which allows more energy from the sun to enter the home while the low U-Factor keeps the heat in.
Blocks out the cold, lets in the light.
Our unique coating stops thermal loss
Note: All values calculated using LBNL Window 7. (See https://windows.lbl.gov/software and https://windows.lbl.gov/software/window for more information on glass optical data and the LBNL Window 7 program.)
Solar Heat Gain Coefficient - (SHGC) - The amount of solar radiation that enters a building as heat. The lower the number, the better the glazing is at preventing solar gain.
UV Transmittance - A portion of the solar spectrum (300 to 380 nm), which represents the energy that accounts for the majority of fading of materials and furnishings. The lower the number, the better the glass is for reducing fading potential.
U-Factor - This represents the heat flow rate through a window expressed in W/m²·K (SI units) or BTU/hr·ft²·°F (IP units), using winter night weather conditions of -18°C (0°F) outside and 21°C (70°F) inside. The lower the number, the better the window system is at reducing heat loss.
LoĒ-180ESC Helps Meet New Requirements
Cardinal I.Q. (Intelligent Quality Assurance Program) ensures the quality of every piece of glass. Using our own patented inspection systems, we thoroughly examine the glass from start to finish.
LoĒ-180ESC is the perfect glass to be both comfortable and compliant with the new requirements for Canada ENERGY STAR.
