About the Event
Helen Sanders will discuss how European and North American calculated fenestration U-factors are calculated differently. There is significant risk of inadvertently confusing the two, since the same window typically has a different EU-calculated U-factor (often lower) than the U-factor calculated using North America’s standard, NFRC 100. These cross-Atlantic differences can easily result in inappropriate product comparisons and performance misinterpretations, especially for projects with international supply chains.
How the center-of-glass U-factor varies with cavity dimension, the factors that impact this trend, and how the optimum cavity dimension is different in Europe compared to North America will be reviewed. How fenestration assembly U-factors are calculated across the Atlantic and why differences exist will be discussed. Finally, to reduce risk in design and procurement, a list of the key questions to ask when presented with any U-factor, will be provided.
Helen has over 30 years’ experience in the glass industry with an M.A.…
