With fuel prices rising, energy-saving glass options could be the next big high-end upsell. Republic now has five glazing options for its high-end Enhancement line, each one with a “fuel savings pledge” ranging from 30% to 40%. The company's Seasonpro HM glass package achieves its 9.62 R-value by using Heat Mirror 88, plus a one-inch double Super G glass spacer system, low-E coating on two surfaces, and krypton gas.

Five “Comfort Glaze” choices offer different benefits in Hurd's Kingsview line. Insulated, low-E, climate control, sun blocker, and super sun blocker glazing options not only offer energy-efficiency, but have DP ratings of up to 50.

Pella's Designer Series gives double- and triple-pane glazing options, and the company's computer simulations have shown that each can decrease energy bills by as much as 17% and 28%, respectively. The firm also offers argon and a variety of low-E coatings.

All of these window options seem appealing on paper, but will customers be willing to pay more up front for estimated savings? Some remodelers don't think so. “People are more interested in the design options, like special grills, or special glass or shapes,” says Terry Quinn of Almar Building & Remodeling in Hanson, Mass. But Bruce Butterfield of Weldon's Windows in Charlotte, N.C., disagrees. According to him, it's all in the approach. “People will pay more. Salespeople should be presenting the higher value glass packs. There should be a portion of the sales presentation dedicated to [explaining] how energy escapes through glass.” Butterfield has found that buyers are more likely to consider adding energy-efficient glass options if they consider the decreases in energy consumption as an increased return on their investment.
