Energy Efficient Windows

What Is Low-E?

Low-E is a clear, low-emissivity coating applied to one side of the glass in our triple-pane windows. This thin coating filters the sun's energy in the summer and reduces heat loss in the winter, making even energy bills look better.

Benefits of Low-E

1. Low-E allows most natural light to enter freely but absorbs a significant portion of short-wave heat energy.
2. In the summer, long-wave heat energy radiating from objects is reflected back outside, lowering cooling cost.
3. In winter, internal long wave heat energy is reflected back inside, lowering heating cost.

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.

Dunn Wright utilizes ENERGY STAR. ENERGY STAR qualified products use less energy than conventional products. And money isn't all you're saving by purchasing products that use less energy-you're also helping to save the environment.

The ENERGY STAR Online Home Improvement Toolbox offers an array of interactive tools to helps consumers make energy-saving, cost-effective upgrades to their homes, enhancing their homes' value and comfort, while also protecting the environment.

Performance

U-factor measures a window’s ability to resist the transfer of heat. The lower the U-factor, the better — and our 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 our 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. Our 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, our 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
