4 Key Parts of an Energy-Efficient Window

You should consider choosing window replacements if you’re planning to spruce up your home this season. This home improvement project doesn’t just enhance your home’s look—it also adds to your comfort and your home’s energy efficiency. For this reason, you should make sure that your replacement windows meet the highest energy performance ratings.

Renewal by Andersen® of Portland can help you with this. As your premier window company, we carry only the most energy-efficient replacement windows in Portland. Their advanced design and construction ensures that they can further improve your home’s look and feel.

Here are the four key factors that make them energy-efficient:

1. Durable Framing Material—Our exclusive Fibrex® material offers a number of benefits that exceed more traditional frame materials like wood, aluminum, or vinyl. This composite combines the strength and insulating properties of wood with the low maintenance features of vinyl. Fibrex doesn’t pit, crack, corrode, or change shape when exposed to extreme thermal changes. It also keeps an airtight seal that prevent costly energy from leaking out of your home.
2. Advanced Glass Packages—When you turn to us for window replacement in Portland, expect your new units to enhance your home’s comfort level. Renewal by Andersen uses High-Performance™ Low-E4® glass. This advanced component helps reduce radiant heat transfer inside your home and protects it from sun damage. When combined with our Fibrex framing material, you can enjoy windows that help keep your rooms thermally comfortable. At the same time, it lowers your reliance on your HVAC system, keeping energy costs to a minimum.
3. Double Glazing—Renewal by Andersen windows have double glazing, which means they have two panes of glass for better efficiency.  We optimize the width of the air space between these two glass panes, preventing drafts from entering your home while ensuring that cooling energy remains inside. Be sure to consider this key factor when choosing window replacement in Portland, OR.
4. Argon Gas Blend—We use argon gas blend as fill in for our double-glazed windows. This cost-effective but high-performing option provides great heat resistance and insulation, boosting your home’s thermal comfort. Our windows also use compressed butyl and specially formulated silicone—a pair of sealants that prevent moisture from leaking between the glass panes.

For windows that excel in beauty and energy efficiency, turn to Renewal by Andersen of Portland. We take pride in the fact that all of our replacement windows are ENERGY STAR®-certified. This means they meet the stringent standards for energy performance set by the program. With our selection, you can make the most of your project.
