Learn About How Low-E Glass Works
While the material of the window frame makes a difference, the energy efficiency of your replacement windows is mostly determined by the glass that is used – which is why we recommend windows with a low-e coating.
Low-e glass gets its name from the low-emissivity film that coats the window pane. Made out of an invisible metal or metal oxide film, this reflective material admits light while redirecting heat back to its source. This means that hot summer air is kept outside, and your home’s heating is reflected back inside in the winter – it’s worthwhile year round!
The low-e coating can be added either during or after the manufacturing process, resulting in either a “soft” or “hard” coat. A soft coat is more efficient, but it’s also more delicate; your window expert can help you choose the right glass for your replacement window.

Other Options and Tips for Energy Efficient Windows
Besides low-e glass, argon filled glass is another option. Argon is a non-toxic, odorless gas that is used in glass windows to prevent condensation and frost from forming on the window and provide improved soundproofing. Argon gas is filled between the panes of glass in a sealed unit to increase energy efficiency.
Another way to bolster your window’s energy performance is to make sure they’re fitted by a professional. Replacement windows especially need to have exact frames to fit the available space. The experts at Assured Exteriors will have no problem ensuring a perfect window for your home that won’t lose any additional air.
Furthermore, All ENERGY STAR windows feature a label with energy performance ratings from the National Fenestration Rating Council (NFRC). The label tells homeowners and contractors about how much heat and light travels through the windows through the U-value, solar heat gain coefficient, and visible transmittance of the windows. This way, you know exactly what your window can offer.
