Glass occupies the biggest area of any window, significantly affecting the window’s overall performance. Renewal by Andersen understands how important this role played by window glass is, which is why we use top-quality glass for all our windows. The glass we use is called low-emissivity (low-E) glass.
What Is It?
Visually, low-E glass is like any other window glass, but it is designed to be extra energy-efficient, limiting the amount of heat that comes in through a window without affecting the level of natural light streaming through. At the same time, low-E glass helps keep heat from inside your home from leaking out. Preventing outdoor heat from coming in and indoor heat from getting out normalizes temperature in your home, reducing your reliance on your HVAC system. This prevents your HVAC system from guzzling power, which will be reflected in your energy bill.
In windows that are predominantly glass, the glazing is especially important as it will have a big effect on the window’s overall performance. Some examples include, casement, sliding, picture and both the bay and bow window design. These window styles feature large glass areas, and, in the case of bay and bow windows, they let in more sunlight than other window styles as well. As a result, your choice of glass is important if you want to ensure a successful window installation project for your home.
Renewal by Andersen Low-E Glass Options
As it is, low-E glass offers reliable performance. Renewal by Andersen improves performance even more by offering several different types of low-E glass. We pair our glazing options with our Fibrex® composite window frames, which increase the durability and energy efficiency of our windows.
We use the best window glazing for window replacement. Our glazing options include:
High-Performance Low-E4 Glass. Our high-performance low-E4 glass is 45% more efficient during the winter months and 56% during summer than regular glass packages. Additionally, this glass has the capability to block up to 84% of harmful UV rays that can degrade the quality of furniture, draperies and artwork. You can consider this the “jack-of-all-trades” glass. Despite being the “entry-level” glass package we offer, it provides excellent energy efficiency no matter what climate you live in.
High-Performance Low-E4 SmartSun Glass. The most energy-efficient glass option offered by Renewal by Andersen, SmartSun glass is 70% more energy-efficient than regular glass in the summer and can block 95% of UV rays. The SmartSun glass has an extra microscopic layer of silver, which explains its increased energy efficiency. Because this glass is so energy-efficient, this is the appropriate choice for sunrooms and other rooms in your home that get a lot of sun.
High-Performance Low-E4 Sun Glass. This glass option is similar in performance to High-Performance Low-E4 Glass, but features a tinted coating that lowers the amount of visible light passing through a window. This provides added privacy, taking away the need for window treatments that completely block out light. We recommend this glass option for bathrooms and bedrooms as well as any other area of the home where privacy is a top priority.
Separately, Fibrex and low-E glass have their merits. In the last part of our blog series, we’ll be talking about how the two work together to form some of the best windows in the market. We offer expert window services and window replacement in San Antonio, TX, and the surrounding areas.
