  • We know a little more about what the Environmental Protection Agency is thinking about the next set of Energy Star criteria, tentatively set to take effect in fall 2013. It issued a document last week, indicating U-value and SHGC performance levels it was considering for windows, doors and skylights. What stood out for me is an apparent EPA decision not to go for an R-5 level of performance... more »

Here in the industry, many of us believe that tax incentives created... more »
