Energy Efficient Windows: How New Windows Can Save You Money

Posted on Fri, Aug 21, 2015

heating-billAs the summer continues to heat up, many homeowners wonder whether they should consider having the old, outdated windows in their home replaced. However, these individuals may be uncertain as to whether or not energy-efficient windows are as beneficial as window companies claim them to be. Without understanding how modern windows save energy, homeowners may be skeptical about investing in new replacement windows. Thusly, the goal of this article will be to help homeowners better understand why new windows are more energy-efficient than old ones, which could save you money on your energy bills.



Glass Coatings

In many modern, energy-efficient windows, a low-emissivity (or low-e) coating is used. This invisible metallic coating sprayed onto the window panes can greatly improve the energy-efficiency of a window. This coating works by reflecting heat and UV rays from the sun, while still allowing light into your home. In this way, low-e glass is able to reflect the outside temperature preventing it from entering your home, keeping your home warm in the winter and cool in the summer. This has been shown to greatly increase a home’s energy-efficiency. Additional coating options that can further increase the energy-efficiency of your new windows include various tinting and reflective coatings.



Layered Glass

Another way in which new windows can help to save you money on your energy bills is through the use of multiple layers of glass which provides superior insulation and UV protection. Older windows are generally single-pane, meaning that they only have one layer of glass, which provides poor insulation. On the other-hand, most modern windows are dual-paned, with some energy-efficient windows being triple-paned. In these windows, there are multiple layers of glass separated by a gas fill. These layers help to reduce temperature transfer between the inside and outside of your home. Furthermore, these additional layers of insulation can block up to 97% of the sun’s UV rays from entering your home. Blocking these UV rays not only helps to make your home more energy-efficient, but also, this can help to prevent your furniture, carpets, and rugs from being faded by the sun’s damaging UV rays.



Enhanced Design

New windows can also help to save energy through their superior design. Decades of expertise has allowed window manufacturers to learn what works best for creating windows that will seal tightly, and that will provide excellent insulation in a home. One way window manufacturers have improved window construction is through the use of better building materials. Traditionally, window frames, and many of their components, were made out of aluminum. The problem with aluminum is that, over time, it can easily break down and rust. Furthermore, aluminum can conduct heat, allowing heat to enter or escape your home. Energy-efficient windows are constructed out of materials, such as vinyl, which are able to provide superior, lasting insulation.  



Superior Seal

Another way in which new windows are able to provide superior energy-efficiency is simply through the tight seal newly installed windows provide. As windows age, they inevitably lose their tight seal. Whether they become warped, cracked, or damaged in some way, most old windows will eventually allow a draft to enter you home. This can cause your HVAC system to have to work harder to heat and cool your home. Newly installed windows can then greatly improve the energy-efficiency of your home through their tight seal.



It is not uncommon, or unwise, for homeowners to be skeptical of products that make unwarranted claims. However, solid evidence has proven on countless occasions how beneficial new replacement windows can be in improving the energy-efficiency of one’s home. Thusly, if you have been considering replacing your windows, you can feel rest assured knowing that you are making a sound investment into your home.
