The window installation market in the US is worth a whopping $5.1 billion. The main reason for such huge demand is that most homeowners seek the benefits of window replacement. Window replacement options increase energy efficiency, making them desirable for most homeowners.
If you think your windows have seen better days, the best course of action would be to replace them. Window replacements are among the high-value renovation projects since they improve property value. New windows are valuable when well installed by boosting curb appeal and energy efficiency.
Despite the amazing energy efficiency ratings, there’s doubt if window replacements really work. That depends on window features and how they have been used on the home. As a homeowner, you’ll need to check whether the window replacement project is worth it before you can invest in it.
Wondering whether window replacements really increase energy efficiency in NC? Continue reading to know how energy-efficient windows work.
Added-Value of New Windows
Energy-efficient windows don’t come cheap, but they’re totally worth it. Think of the added value such energy-efficient windows offer your property. As a result, your renovation project banks on the added value that new windows bring about.
Here are a few ways to assess the value addition in energy-efficient window replacements.
Price Differentiation
You’ll pay more for energy-efficient windows for any home improvement compared to the standard options. In truth, the price disparity between the two commodities doesn’t vary greatly.
For instance, the mark-up for a triple-pane window will only cost 20 – 30% more than double-pane options. The higher the number of parts to be used, the more the cost. However, the cost difference evens out in the vast potential savings you make in energy expenses.
Return on Investment (ROI)
A quality window replacement in Charlotte, NC, will likely last you for many years to come, which is a huge plus. It gets better since you can recoup some of the project costs in the property value on resale.
Upscale vinyl window replacements have an ROI of 74% – higher than most renovations. The ROI boosts returns that coincide with the energy efficiency you enjoy in its use at home.
Value Gains
Experts suggest that heat gain or loss through your window is responsible for 25% to 30% of energy use. Selecting energy-efficient windows is therefore critical for reducing energy expenditure. An upgrade to energy-efficient window replacements helps you save considerably year on year.
New windows with an excellent energy rating prevent energy gain or loss from home. As a result, you don’t have to use your HVAC as you’d often use. Such value gains ensure you can save some dollars while enjoying a comfortable indoor climate.
What Makes Window Replacements Energy-Efficient?
There’s no denying that energy-efficient window replacements are a tad different from regular windows. Although they perform similar functions, window replacements have extra features, making them unique.
So, what makes a window energy efficient? Continue reading to learn energy-efficient factors on window replacements below;
Glass Panes
The window surface can’t offer the much-needed insulation. As a result, it offers a weak link in a home, resulting in the entry or escape of heat from home.
We now have double and triple-paned windows to remedy the heat gain or heat loss problem. Such windows use multiple levels of glass sheets to seal shut the air and prevent it from escaping.
The glass panes leave spaces between them to create air pockets that prevent heat transfer. The effect is an energy-efficient window to save you money for your heating needs.
Window Frames
Most people will think of the window as the glass pane alone, but there’s not much you can do with a frameless window. Window frame material plays a huge role when it comes to energy-efficient operations.
There are a range of window frame materials, each with different efficiencies as shown below;
• Aluminum window frames – least efficient since they conduct heat
• Wood frames – offer excellent insulation properties
• Vinyl window frame – offer great resistance to UV light and great insulation
• Fiberglass frames – most energy efficient
• Composite – has great insulation since it’s made using wood and plastic resins
For a window to achieve total energy efficiency, it has to be paired with a frame material that’s a great insulator. High-quality window frame materials prevent heat transfer and insulate the windows better. You thus enjoy more efficient cooling and heating in your home.
Coatings
The glass coatings are what separates the regular windows from the energy-efficient options. The glass coatings act as a film to prohibit sunlight movement or penetration into the home.
A specific coating that’s been widely used is the Low-E (low-emissivity coatings). The coatings are designed to keep heat in your home during the winter. They’ll equally keep out sun rays during the summer, thus avoiding interior heating.
Low-E coatings are perfect for North Carolina window replacements to avoid heat gain in the southern climates. In areas where heat gain is desirable, like North America, the Low-E coatings are used in reverse. As a result, they allow more sunlight in, creating ideal temperatures for houses in the cold months.
Gas Fills Insulation
The air between the glass panes on window replacements doesn’t offer complete resistance to heat transfer. Experts thus have gas fills between glass panes to help insulate your windows better.
Gases such as Argon and Krypton are inert, thus offering better insulation than air. As a result, the gas fills have been used on higher-grade window replacements to improve resistance to heat transfer. Additionally, the gases are non-toxic and odorless, making them comfortable to have in your home.
Window Spacers
Spacers on your windows are applied to create the perfect distance between the glass panes. As a result, they’re instrumental in the energy efficiency properties of windows at home.
The non-metal and metal hybrid spacers tend to insulate the windowpane edges. As a result, they can curb heat transfer, thus improving energy efficiency.
Consider the Window Energy Ratings
Every window has a rating based on the manufacturer’s assessment of its energy efficiency. You should thus assess the window energy ratings to ensure they’re perfect for your home.
There are several window energy rating scales, namely.
The U-Factor
U-factor rating for windows falls between 0.20 and 1.2, which indicates a window’s resistance to heat transfer. The lower the U-factor rating, the better resistance your window offers to heat flow.
The window’s insulating value can be indicated by the R-value, which you calculate by inversing the U-factor.
Window SHGC Rating
SHGC refers to the Solar Heat Gain Coefficient, and it shows how well a window blocks the sun’s heat. The SHGC calculates how much solar radiation is admitted through a window and released inward.
The SHGC rating is expressed using numbers between 0 and 1 – Low numbers indicate less solar heat transmission on your windows.
The VT (Visible Transmittance) Rating
The VT rating in a window shows the optical properties, in essence, how much visible light can pass through. The amount of visible transmittance is calculated using numbers between 0 and 1. A higher VT means more light is transmitted.
Therefore, window replacements with low VT levels are suitable for cinema rooms. Brighter spaces such as your kitchen should help you avoid low VT levels.
Air Leakage
The air leakage rating accounts for the amount of air in cubic feet passing through a square foot of a window (cfm/sq. ft). Cracks in your window assembly will cause the air leakage to skyrocket. The more air lost, the lower the energy efficiency, and the higher the air leakage rating.
Condensation Resistance (CR)
Accounts for the ability of your window to prevent condensation from forming on the inside a window. The CR rating is expressed between 0 and 100, and a higher score indicates how good your window is at preventing condensation.
Work With Energy-Efficient Window Installers
Now that you know how energy-efficient windows work, who do you entrust to install them for you? Energy-efficient window replacements are as good as whoever installed them, so find a great installer.
Not all window replacement contractors are the same, so you don’t settle on the first option you come across. Conduct extensive market research to end up with a trusted home window replacement near me.
