U factor Versus R Value?
A lot of consumers are hearing the new buzz word “U factor” and asking themselves what does U factor mean? What about R values? Doesn’t R value refer to energy values? Let me clarify things with the following definition. Both U-factor and R-value are measures of a material’s insulating performance. The former is a measurement of heat transfer; the latter measures heat resistance. Scientists and Engineers invented the word “U factor” to measure the rate of heat transfer through 1 square foot of material. U factors are generally used to measure window efficiency. U factors are not used for other building materials, generally speaking. The lower the U factor, the better insulated the window. Great Lakes Seabrooke windows offer a triple pane, double glazed glass package that is one of the most efficient systems available today. In fact, the U factor for the Maxuus 7.6 glass system is .18 at the center of the glass, and an overall rating of .26. These windows can reduce your energy consumption by as much as 50%! Great for your wallet, and our planet. get more info at http://www.seabrookewindows.com
