See-Thru Energy Efficiency

Sometimes the best endorsement a product can have is when it's installed inside a professional remodeler's house. “We use 'em. We install 'em. And I use them in my own home. Why not put the best products in there?” says Scott Sevon, president of eco-friendly Sevvonco.

Sevon recommends Pella Designer Series windows, which feature both double- and triple-pane glazing options to reduce air infiltration and keep the home's shell intact. The windows allow room for both a treatment and a muntin between panes of glass for added protection and flexibility. The series, on the market since 2005, comes in several configurations; roughly ¾ of the windows Sevvonco installs are in casement form. Fabric shades open from the top down to allow natural light in from the top while covering the bottom. Shades and blinds extend to the inside edge of the window sash for extra privacy.

From a company standpoint, Sevon is perfectly happy with Pella's product line for its green characteristics. “We've been using Pella for 26 years. They educate us. They recycle or reuse all of the products that are involved in the manufacturing process,” says Sevon. “They've been extensively tested; that's the truth. I've seen it done. A group of guys test air infiltration right there on the factory floor. And they meet all the Energy Star requirements, too.”

But it's the inside that counts to Sevon. According to Pella, double-paned glass can reduce energy costs up to 17 percent and triple-paned glass can decrease energy bills by as much as 28 percent compared to a single-pane wood window. But, says Sevon, he's not as concerned with studies as he is with performance. “People want to save money. Obviously windows are a big, big source of energy loss. And old homes are the most inefficient monsters on the planet. There are 134 million of them out there right now that are over 30 years old,” he says.
