7 Elements Of Energy Efficient Windows | Dallas, TX
Energy prices in 2022 soared to their highest level since August 1981, rising by a staggering 15.8% from the previous year. Homeowners in Dallas, TX are finding more innovative ways to reduce their energy spending without compromising comfort. One of the most effective ways to do this is by installing energy efficient windows.
While windows provide natural lighting and fresh air, they’re severely lacking in the energy-saving department. About 30% of air-conditioning and heat energy is lost through windows. As such, this is where energy efficient windows come in. Energy efficient windows are designed to reduce heat transfer from the inside to the outside and vice versa. They also keep conditioned air from escaping outside, thus conserving the internal temperature and saving energy.
So, what makes these windows energy efficient? Well, keep reading to find out.
The Frame Material
Window frames have always been a consideration on the aesthetic front, but did you know they also determine how energy efficient your windows are? The type of framing material directly impacts your windows’ ability to retain energy. For instance, vinyl frames are better for insulation than aluminum frames.
The durability of the window frame also plays a role in your window’s energy efficiency. Frames that are less likely to warp or damage are better for the long-term efficiency of your windows. That said, here are some of the most common window framing materials:
- Wood
- Composite
- Aluminum
- Vinyl
- Fiberglass
Fiberglass is hands down the most energy efficient framing material of the bunch. Vinyl is also a great choice for energy efficient windows and costs a lot less than fiberglass.
The Number of Panes
The primary means of heat loss in windows is through the glass. Adding an extra pane or two insulates the window to prevent heat loss. The more panes a window has, the more energy efficient it is.
The panes in multi-pane windows aren’t layered one on top of the other. Instead, they’re spaced, with the space between each panel filled with gas. This gas acts as insulation, preventing heat from escaping or getting into your home.
You can buy double, triple, or even quadruple-paned windows, depending on the level of insulation you want. However, because of the extra panes, these windows cost more than regular windows with a single pane.
Weatherstripping
Weatherstripping is plastic tightly installed along the edges of windows to keep drafts out. This helps to seal air leaks and conserve the heat inside your home. The type and amount of weatherstripping you have on your windows will influence how energy efficient they are. Vinyl works best for weatherstripping, but even rubber and foam tape will do.
Low-E Glass Coating
A low-emissivity, or “Low-E,” glass coating is a thin, microscopic layer of silver and ceramic materials coated on window panes in layers. This coating reduces the amount of infrared and ultraviolet radiation coming through your windows. It’s typically installed on the inner side of the outside window pane.
A Low-E coating helps reduce the heat entering your home without compromising on natural lighting. You still get the sunlight, only without the heat.
Warm Edge Spacer
Spacers are what separate the panes in the multi-pane windows we discussed above. They also allow room for the expansion and contraction of the energy efficient windows and provide a moisture barrier to keep moisture from seeping into the windows.
A warm edge spacer also helps insulate the windows by preventing heat transfer between the panes and window frames. These spacers, combined with the gas fill, provide an airtight insulation layer that contributes immensely to a window’s energy efficiency.
The Gas Fill
The type and amount of gas between the panes in multi-pane windows also contribute to the window’s overall energy efficiency. Argon is the gas of choice for most manufacturers since it’s denser than air, odorless, and non-toxic. Their higher density makes them excellent for insulation and easier to install.
The Installation Expertise
Proper installation is key to having a functioning, energy-efficient window. Even a combination of a Low-E coating, double panes, and weather stripping will mean nothing if the installation is subpar.
The sealing around your windows should be airtight to prevent drafts. They should also open and close easily and completely. Anything less, and your windows’ energy efficiency plummets.
As such, be sure you only settle on the best contractor for your window installation. These half-baked contractors with low rates will do more harm than good. So explore your options and settle for nothing but the best.
Energy Ratings You Should Know When Picking an Energy Efficient Window
When in the market for energy efficient windows, you’re likely to come across some very confusing terms and acronyms. To help you out, here are a few ratings to keep in mind while literally window shopping:
- U-Factor: This is a measure of a window’s insulating capability. The figures range from 0.10 to 1.20, with a lower figure indicating a more energy efficient window. Of course, the more your window insulates, the better it conserves energy.
- Visible transmittance (VT): This measures how much visible light enters through your window. The range is between 0 and 1; the higher the number, the more light enters through the window. Windows that let in too much light are less energy efficient. That is unless you have a Low-E coating that reduces heat-laden infrared and ultraviolet radiation.
- Solar Heat Gain Coefficient (SHGC): This is the amount of solar heat that enters your home from the outside. It ranges from 0 to 1. The lower the figure, the lower the amount of solar heat entering your home, and the more energy efficient your windows are.
