How to Buy Energy Efficient Windows involves understanding the factors that affect a window’s energy efficiency, such as the type of glazing, frame material, and installation method. Energy-efficient windows can help reduce heat loss in the winter and heat gain in the summer, leading to lower energy bills and a more comfortable home.
Investing in energy-efficient windows offers several benefits, including:
- Lower energy bills
- Increased home comfort
- Reduced carbon footprint
- Increased home value
When buying energy-efficient windows, it is important to consider the following factors:
- Glazing: The type of glazing, such as double or triple glazing, can significantly impact a window’s energy efficiency.
- Frame material: The frame material, such as vinyl, wood, or aluminum, can also affect a window’s energy efficiency.
- Installation: Proper installation is essential to ensure that your windows are energy efficient.
By following these tips, you can choose energy-efficient windows that will help you save money and improve your home’s comfort.
1. Glazing
When it comes to buying energy-efficient windows, the type of glazing is a key factor to consider. Glazing refers to the glass panes that make up the window, and the number of panes can have a significant impact on the window’s energy efficiency.
- Single glazing is the least energy-efficient type of glazing, as it consists of only one pane of glass. This means that heat can easily escape through the window in the winter and enter the home in the summer.
- Double glazing is more energy-efficient than single glazing, as it consists of two panes of glass with a vacuum or gas-filled space between them. This helps to insulate the window and reduce heat loss.
- Triple glazing is the most energy-efficient type of glazing, as it consists of three panes of glass with two vacuum or gas-filled spaces between them. This provides even better insulation than double glazing and can help to reduce heat loss even further.
When choosing energy-efficient windows, it is important to consider the climate in your area. If you live in a cold climate, triple glazing may be the best option to reduce heat loss. However, if you live in a milder climate, double glazing may be sufficient.
2. Frame material
When choosing energy-efficient windows, the frame material is another important factor to consider. The frame material can affect the window’s insulation value, air leakage, and durability.
The most common frame materials are:
- Vinyl is a good choice for energy-efficient windows because it is a good insulator and does not conduct heat or cold well. Vinyl windows are also relatively inexpensive and easy to maintain.
- Wood is a natural insulator, but it is not as good as vinyl or aluminum. Wood windows are also more expensive than vinyl windows and require more maintenance.
- Aluminum is a good conductor of heat and cold, so it is not as energy-efficient as vinyl or wood. However, aluminum windows are strong and durable, and they can be a good choice for areas with high winds.
When choosing a frame material for your energy-efficient windows, it is important to consider the climate in your area and your budget. Vinyl windows are a good choice for most climates and budgets, but wood or aluminum windows may be a better choice for specific needs.
3. Installation
When it comes to buying energy-efficient windows, installation is just as important as the type of windows you choose. Even the most energy-efficient windows will not perform as well as they should if they are not installed properly.
Here are a few reasons why proper installation is so important:
- Air leaks: Improper installation can create gaps around the windows, which allows air to leak in and out. This can significantly reduce the energy efficiency of your windows.
- Moisture damage: Improper installation can also lead to moisture damage around the windows. This can damage the windows and the surrounding structure, and it can also lead to mold and mildew growth.
- Reduced lifespan: Improper installation can shorten the lifespan of your windows. Windows that are not installed properly are more likely to fail prematurely.
To ensure that your windows are installed properly, it is important to hire a qualified contractor. A qualified contractor will have the experience and expertise to install your windows correctly and ensure that they are energy efficient.
Proper installation is an essential part of buying energy-efficient windows. By hiring a qualified contractor to install your windows, you can ensure that your windows will perform as well as they should and that you will enjoy the benefits of energy efficiency for years to come.
4. Energy efficiency ratings
Energy efficiency ratings provide a standardized way to compare the energy performance of windows. The ENERGY STAR label is a government-backed program that helps consumers identify energy-efficient products, including windows. Windows that earn the ENERGY STAR label meet specific energy efficiency criteria, which vary depending on the climate zone.
-
Importance of energy efficiency ratings
Energy efficiency ratings are important because they can help you choose windows that will save you money on your energy bills. Windows with higher energy efficiency ratings are better at insulating your home, which can reduce heat loss in the winter and heat gain in the summer. This can lead to lower energy bills and a more comfortable home.
-
How to find energy efficiency ratings
You can find energy efficiency ratings on the NFRC label, which is attached to all new windows. The NFRC label provides information on the window’s U-factor, solar heat gain coefficient (SHGC), and visible transmittance (VT). These ratings measure the window’s ability to insulate, block heat gain, and allow light to pass through.
-
ENERGY STAR windows
ENERGY STAR windows meet specific energy efficiency criteria, which vary depending on the climate zone. To earn the ENERGY STAR label, a window must have a U-factor of 0.30 or less and a SHGC of 0.30 or less in northern climate zones. In southern climate zones, the U-factor must be 0.35 or less and the SHGC must be 0.25 or less.
-
Benefits of ENERGY STAR windows
ENERGY STAR windows can provide a number of benefits, including:
- Lower energy bills
- Increased home comfort
- Reduced carbon footprint
- Increased home value
By choosing windows with high energy efficiency ratings, you can save money on your energy bills and improve your home’s comfort. ENERGY STAR windows are a great option for homeowners who are looking for energy-efficient windows that meet high performance standards.
