Renewal by Andersen® Energy-Efficient Glass Packages

December 07, 2017

At Renewal by Andersen®, we regard glazing as one of the most important components of our replacement windows and patio doors. This is why every single replacement window unit we have features High-Performance™ Low-E4® glass, available in three different glass packages.

Renewal by Andersen® Energy-Efficient Glass Packages

Here’s a detailed look at each.

Dual-Panel Glazing

One of the challenges of building energy efficient replacement windows and patio doors is the glazing. Glass is a naturally conductive material, and conventional means of insulation would defeat the purpose of having glass panels in the first place. Traditional single-panel glazing has proven to be a problem, as it readily facilitates thermal transfer that leads to heat loss in the winter and heat gain in the summer.

The solution is a dual-panel design. Two glass panels separated by insulated spacers eliminate contact between interior and exterior surfaces, dramatically reducing conductivity. When combined with low-emissivity (Low-E) coatings, dual-panel glazing provides a simple yet effective solution against thermal transfer.

Dual-panel glazing has since become standard on every energy-efficient window style we offer, from the humble double hung window to oversized window walls. Our replacement windows are certified by the National Fenestration Rating Council and ENERGY STAR® for energy efficiency.

Our Glass Packages

As stated above, we offer three glass packages:

  1. High-Performance Low-E4 glass – Our standard glass packages have advanced features that put them ahead of most dual-panel glazing in the market. The Low-E4 coating blocks up to 84% of harmful UV rays. We fill the space between with an insulating custom argon gas blend. This glass package features up to 45% and 56% more energy efficiency in winter and summer, respectively, compared with ordinary dual-panel glazing.
  2. High-Performance Low-E4 SmartSun™ glass – Our most energy-efficient glass package features 70% energy efficiency in summer and 49% in winter. If you’re worried about the effects of direct sunlight on your fabrics and furniture, choose this option; it blocks 95% of UV rays while admitting light just like clear glass.
  3. High-Performance Low-E4 Sun glass – Sometimes natural light can be too bright for comfort. Our High-Performance Low-E4 Sun glass features a subtle tint that tames harsh sunlight without sacrificing energy efficiency.

Hear From Our Customers

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!
