Making an investment in superior windows and doors will pay off down the road. In lower energy bills. Less fading damage to furniture and carpet. And above all, the comfortable enjoyment of your home. That?s why Pella® products are designed with a variety of options and glass technologies for outstanding energy efficiency.
What makes our windows and doors perform so well? Lots of things. You see, building an energy-efficient window isn?t a one-size-fits-all kind of process. No single solution is right for every home or every climate. But you can count on Pella for the solution that?s right for you. Glass options.
Different climates require different window technologies for best performance. We offer options ranging from standard clear insulating glass to energy-saving, argon-filled1, Low-E insulating glass. Double- or triple-pane glass options with between-the-glass blinds or fabric shades can further increase energy savings and can even reduce outside noise — like lawn mowers and traffic — by up to 80%2. Laminated insulating glass is another great choice for increased energy efficiency and sound reduction.



Performance.
U-factor measures a window?s ability to resist the transfer of heat. The lower the U-factor, the better — and Pella products offer some of the lowest U-factor in the industry. In fact, we have some products that have a U-factor that significantly exceeds ENERGY STAR® guidelines. What?s more, our superior weatherstripping and welded-corner gasket design make Pella casement, awning and fixed windows some of the best-performing windows available today.
Coatings.
High-performance glass coatings help you save on energy costs, too. Pella?s optional Low-E glass coatings help reduce heat transfer through the glass. And they reduce UV rays, as well as other light, that can fade carpets, walls and furniture. For example, Pella?s Solar-E coating can help keep homes in warm, sunny climates cooler. Available on Designer Series triple-pane windows and patio doors, Solar-E blocks most of the sun?s heating and fading rays, while still allowing a high percentage of visible light to shine through.
