Glass so smart, it controls comfort.
Note: All values calculated using Window 7.4. (See http://windows.lbl.gov/software/default.htm and http://windows.lbl.gov/materials/optical_data/default.htm for more information on glass optical data and the Window 7.4 program.) Emittance of ordinary (pyrolitic) low-E is 0.16.
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.
Fading Transmission - The UV Transmittance is determined as an average for wavelengths 300 -380 nm. UV Damage Weighted Transmittance (Tdw) is the weighted average for wavelengths 300 – 780 nm (based on CIE 89/3). This region includes all of the ultraviolet energy and part of the visible spectrum, and will give the best representation of relative fading rates. The lower the number, the better the glass is for reducing fading potential of carpets and interior furnishings.
U-Factor - This represents the heat flow rate through a window expressed in BTU/hr·ft²·°F, using winter night weather conditions of 0°F outside and 70°F inside. The smaller the number, the better the window system is at reducing heat loss.
Cardinal actively supports and participates in the National Fenestration Rating Council (NFRC). Windows with LoĒ - 180 that are rated and certified by the NFRC can comply with Energy Star™ requirements in all regions of the country. Northern zone will likely require the addition of LoĒ-i89 on the 4th surface to comply with U-Factor requirements. (See https://www.energystar.gov/products/certified-products/detail/residential-windows-doors-and-skylights for more information on the Energy Star windows program.)
LoĒ-180 always exceeds expectations.
LoĒ-180 can be purchased in hurricane-resistant laminated glass, as well as in a variety of shapes and sizes.
To learn more about LoĒ-180 and other Cardinal Glass products, ask your window manufacturer, contractor or architect.
