10 MAIN FEATURES OF ENERGY EFFICIENT WINDOWS IN Raleigh NC
If you're thinking about installing energy-efficient replacement windows in Raleigh, it's a good idea to check out this article. We're going to discuss the key features that make replacement windows efficient, reliable, and a smart investment. Before you invest in an energy-efficient window system, make sure to look for these top 10 qualities and characteristics in a replacement window:
1. ENERGY PERFORMANCE RATINGS
Replacement windows are installed primarily for their energy-saving abilities. In fact, energy performance ratings are used to analyze how efficiently these windows conserve energy. These ratings are determined based on certain factors such as:
· Solar heat gain coefficient (SHGC)
The SHGC, or solar heat gain coefficient, represents the amount of solar radiation that enters through your windows and is measured in fractions. When the SHGC value is lower, it means less heat will be transmitted through your windows.
· U-factor
The U-factor is basically a measure of how well an energy window can keep in the heat, not from the sun though. The lower the U-factor, the more energy efficient the window is. So, if you want to make sure that heat is staying put and not escaping, look for a U-factor of less than 0.35. That way, you can minimize the heat transfer.
· Air leaks
The air leak rating is an important factor to consider when it comes to replacement windows in Raleigh. You want windows that have a low air leakage, so you don't have to worry about unnecessary drafts or energy inefficiency.
2. LOW- EMISSIVITY GLASS
Emissivity is a measurement that tells us how well a glass can absorb or reflect radiant energy. It's actually pretty important because it affects how efficient a replacement window is.
Now, when we talk about Low-E, we're talking about a special reflective coating that they put on the glass. So what this coating does is it helps reflect sunlight, which is great for keeping your home cool in the summer. But it also helps keep the heat inside during the winter months, so you're not losing all that precious warmth through your windows. Cool, right?
3. ARGON GAS
A replacement window has multiple panes separated by a spacer bar and seals to create a sealed environment. They use argon gas between the glass panes because it boosts the efficiency of replacement windows in Raleigh by improving insulation.
Argon gas has around 34% less thermal conductivity than air, so it's great for insulation. Plus, argon fillings are durable and won't leak even after years of installing energy-efficient windows. Only about 5% of the gas level will drop over 25 years. So, you won't have to worry about losing its effectiveness over time.
4. FRAMES
When it comes to energy-efficient windows in Raleigh, window frames play a crucial role. They act as the structural backbone of each window unit, ensuring its long-term operation. If the frame is weak, it might fail to support the weight of the glass, potentially causing harm. So it's important to pay attention to the strength of the frame!
Improving the thermal resistance of the frame can actually have a significant impact on the overall efficiency of replacement windows in Raleigh. It's interesting to note that different types of frames offer their own unique benefits.
Composite frames
Composite frames are actually really stable and they have the same structural and thermal properties as a traditional wood frame. Plus, they're really tolerant to decay and moisture problems, which is pretty awesome.
Fiberglass window frames
Fiberglass window frames are great because they're dimensionally stable and have air cavities that can be filled with insulation. This means they perform better thermally compared to other frames.
Vinyl frames
Vinyl frames are actually made up of PVC material, which is really durable and even has a protective layer to withstand those harsh sunrays. They're also moisture resistant, so you don't have to worry about any damage there. And the best part? They provide superior insulation compared to wooden frames. So you can keep your home comfy and cozy all year round!
5. INTERCEPT SPACERS
An Intercept Spacer, which has a U-shaped design, helps the glass and sealant move along with the natural expansion and contraction of insulating glass during temperature changes throughout the day. This supports the longevity of the seal and enhances gas retention.
6. STYLE OF THE WINDOW
Replacement windows' efficiency also depends on their style and design. For example, windows with a large glass area are more energy-efficient because they allow plenty of sunlight in the house. On the other hand, windows with an operable design let the breeze inside the house, which helps the HVAC system function more efficiently.
When installing replacement windows in Raleigh, one of the most crucial characteristics to keep in mind is to always choose them according to the orientation and size of the glass to maximize the sun's heat in winter and minimize it in the summer.
7. WEATHER SEALING
If you're looking to get a replacement window system in Raleigh, it's important to make sure it's properly weather sealed. The weather sealing ability of a window is crucial for keeping out air and water.
When you're checking out different energy windows, don't forget to look for weather stripping around the edges of the sashes where the window meets the master frame. It's always a good idea to make sure everything is sealed up tight!
8. SPECTRALLY SELECTIVE COATINGS
These windows have a special kind of low-E coating that reflects specific wavelengths while still being transparent to others. These coatings are designed to reflect the infrared part of the solar spectrum, while letting in more visible light. They can block up to 70% of unwanted heat that usually comes through replacement windows without this technology.
9. OPERATING TYPE
When selecting replacement windows in Raleigh, North Carolina, another important aspect to consider is the operating type of the system. This is because certain operating systems have lower air leakage compared to others. So it's really essential to choose carefully which system will best meet your needs.
10. INTERLOCKING MEETING RAIL
Hey, when it comes to double hung and gliding energy windows, you definitely want to make sure the frame has an interlocking meeting rail. This is basically where the window meets in the middle, and there's a neat little channel that seals everything up tight when the window is closed.
Let me tell you, this feature is a game-changer. It keeps out drafts like a champ and seriously reduces any condensation problems. Trust me, you don't want to miss out on this one. If the energy window you're eyeing doesn't have it, just move on to the next option, my friend.
