What Are Good Energy Efficient Windows?

By Guardian Windows | Date July 2, 2024


When it comes to keeping your home comfortable and your energy bills low, energy-efficient windows are a game-changer. But what exactly makes a window energy efficient, and how can you choose the best ones for your home, especially if you live in a city like Houston? Let’s dive into the world of energy-efficient windows and find out.

Understanding Energy Efficient Windows

Energy-efficient windows are designed to prevent your heated or cooled air from escaping your home. They feature advanced technologies like low-E coatings, gas fills between panes, and improved frame materials.

What Makes a Window Energy Efficient?

Energy-efficient windows typically have multiple panes of glass (double or triple), specialized coatings that reflect heat, and insulating gas fills like argon or krypton. These components work together to reduce the transfer of heat, keeping your home warmer in the winter and cooler in the summer.

Benefits of Energy Efficient Windows

Energy-efficient windows offer numerous benefits that go beyond just saving money on your energy bills.

Lower Energy Bills

One of the most compelling reasons to switch to energy-efficient windows is the significant reduction in your energy bills. By improving insulation, these windows reduce the amount of work your heating and cooling systems have to do.

Improved Comfort

With energy-efficient windows, you can say goodbye to drafts and cold spots. These windows help maintain a consistent indoor temperature, enhancing your overall comfort.

Enhanced Home Value

Installing energy-efficient windows can also boost your home’s value. Potential buyers recognize the long-term savings and comfort benefits, making your home more attractive on the market.

Types of Energy Efficient Windows

Choosing the right type of energy-efficient window depends on your specific needs and the climate where you live.

Double-Pane Windows

Double-pane windows feature two layers of glass with an air or gas-filled space between them. This design significantly reduces heat transfer compared to single-pane windows.

Triple-Pane Windows

For even greater insulation, triple-pane windows have three layers of glass and two insulating spaces. They offer superior energy efficiency, particularly in extreme climates.

Low-E Glass Windows

Low-emissivity (Low-E) glass windows have a special coating that reflects infrared light, keeping heat inside in the winter and outside in the summer. This coating also protects your furnishings from UV damage.

Key Features to Look For

When shopping for energy-efficient windows, there are several key features to consider.


The U-factor measures how well a window prevents heat from escaping. A lower U-factor indicates better insulation.

Solar Heat Gain Coefficient (SHGC)

SHGC measures how well a window blocks heat from sunlight. In hot climates like Houston, a lower SHGC is preferable to keep your home cooler.

Visible Transmittance (VT)

VT measures how much visible light passes through a window. Higher VT means more natural light, which can reduce the need for artificial lighting.

Best Energy Efficient Windows for Home Houston

Choosing the best energy-efficient windows for your home in Houston requires considering the local climate and trusted brands.

Climate Considerations

Houston’s hot and humid climate means you need windows with a low SHGC to minimize heat gain while maintaining good insulation with a low U-factor.

Top Brands in Houston

Some top brands offering energy-efficient windows suitable for Houston’s climate include Pella, Andersen, and Marvin. Each provides a range of products designed to enhance energy efficiency and withstand local weather conditions.
