Renewal by Andersen® of Seattle windows are masterfully engineered to deliver exceptional energy efficiency for decades. Our products meet ENERGY STAR’s requirements for the Northern Climate Zone with excellent NFRC ratings. The unique combination of features they possess has earned us the prestigious and elusive Green Seal certification.
Here are the factors that make our replacement windows so energy efficient:
Spectrally Selective Low-E Coating
Our windows have high-performance glass with a spectrally selective, multi-layer Low-E coating to provide incredible benefits for heating, cooling, daylighting and UV protection. This is the primary reason our Low-E4® SmartSun™ is 70% more energy efficient in the summer and 47% more energy efficient in the winter than regular glass.
Our patented framing material insulates 700 times better than aluminum. Plus, its stability and rigidity are on par with wood, minimizing the risk of leaks.
Argon Gas Blend
We optimize an argon gas filling to create an efficient thermal barrier between your home and the outside world. We use our own insulating gas blend in our replacement patio doors.
Stainless Steel Spacer
The spacer system of our windows is made from stainless steel for maximum strength and longevity. It’s so durable we can afford to use less material to create a thinner spacer wall without compromising glass stability.
We’re one of the few window contractors that uses two specialized sealants to form a reliable gas barrier and keep the space in place. We remove the Low-E coatings around the embedded glass edge, creating a clean surface for maximum sealant adhesion.
From construction to installation, attention to detail is one of our strongest values. We live by the “Measure twice, cut once” adage, precisely custom-building every window to fit within 1/16th of an inch of the existing opening. With our Certified Master Installers, you can rest assured that the installation will be flawless.
