Enhancing Home Energy Efficiency With the Right Windows


In today’s world, where sustainability and cost savings are extremely important to homeowners, home energy efficiency has become crucial in residential living. An often overlooked but significant aspect of enhancing a home’s energy efficiency is the choice of windows. Choosing the appropriate windows not only fills our homes with natural light but also plays a crucial role in regulating indoor temperatures, enhancing both comfort and energy efficiency.

Our team at Freeman Exteriors is committed to providing superior exterior solutions. One of the ways we help homeowners is by placing a strong emphasis on the importance of selecting the appropriate windows to boost your home’s energy efficiency. 

The Role of Windows in Energy Efficiency

According to the U.S. Department of Energy, windows can account for 25% to 30% of residential heating and cooling energy use. If not properly selected or installed, windows can be a major source of energy loss. Selecting the right type of windows can help keep your home cooler during summer months and warmer throughout winter, thereby reducing the reliance on your heating and cooling systems, which can play a role in reducing your energy costs. This not only saves energy but also cuts down on utility bills and reduces your home’s carbon footprint.

Features of Energy-Efficient Windows

1. Glass Coatings and Glazings

Modern technology has introduced low-emissivity (Low-E) coatings on window glass, which reflect infrared light, keeping heat inside in winter and outside in summer. Certain windows feature spectrally selective coatings designed to filter out 40% to 70% of the heat typically transmitted through insulated window glass or glazing, all while preserving the amount of natural light entering the home.

2. Gas Fills

Some energy-efficient windows contain inert gases between the panes, typically argon or krypton, which have better insulation properties than air. These gases reduce heat transfer through the window, enhancing thermal performance and further improving home energy efficiency.

3. Quality Frame Materials

The material of the window frame plays a significant role in its overall energy performance. Materials like vinyl, wood, fiberglass, and some composites offer greater thermal resistance than traditional aluminum frames. These materials help minimize heat and cold transfer into your home, contributing to improved energy efficiency.

4. Proper Installation

Even the most energy-efficient windows have to be correctly installed to ensure they provide accurate energy efficiency. A poorly installed window can result in leaking air and energy loss. Trusting experts like Freeman Exteriors for the installation can guarantee that your windows will be fitted accurately, maximizing their performance and durability.

Benefits of Installing Energy-Efficient Windows

1. Lower Utility Bills

Investing in energy-efficient windows can lead to substantial savings on monthly utility bills by lessening the demand for heating and cooling systems to maintain indoor comfort levels. Over time, this makes them a wise and cost-effective investment.

2. Enhanced Comfort

Energy-efficient windows play a crucial role in maintaining consistent temperatures throughout your home, effectively eliminating hot and cold spots that may arise with less efficient windows. This contributes to a more comfortable living environment year-round.

3. Increased Home Value

Upgrading to high-quality, energy-efficient windows can increase the resale value of your home. Prospective buyers appreciate the benefits of energy efficiency and the reduced utility costs associated with it.

4. UV Protection

Many energy-efficient windows come with coatings that block harmful UV rays, protecting your furniture, carpets, and curtains from fading and damage caused by sun exposure.

5. Environmental Impact

By reducing energy consumption, energy-efficient windows contribute to lower greenhouse gas emissions and a smaller carbon footprint for your home. This aspect holds particular significance for homeowners who prioritize minimizing their environmental footprint.

Types of Energy-Efficient Windows

When looking for energy-efficient window options, it is key to consider features that improve insulation and reduce energy consumption. Here are some top choices:

  1. Double Glazed Windows: These have two panes of glass with a space between them, often filled with an inert gas like argon, which acts as insulation.
  2. Triple Glazed Windows: Similar to double glazed but with three layers of glass, offering even greater insulation and energy efficiency.
  3. Low-Emissivity (Low-E) Windows: These windows are coated with a thin metallic layer designed to reflect infrared light, thereby retaining heat indoors during winter months and keeping heat out during summer, contributing to overall energy efficiency.
  4. Thermally Broken Aluminum Windows: Aluminum is a good conductor of heat, but “thermally broken” aluminum frames have a plastic section that reduces heat transfer, improving insulation.
  5. Fiberglass Windows: Fiberglass frames are durable, strong, and resist weather and temperature changes, making them great for energy efficiency.
  6. Vinyl Windows: Vinyl is a low-cost, energy-efficient material that doesn’t transmit heat, helping to keep indoor temperatures stable.
  7. Wooden Windows: Wood naturally insulates well compared to metal, though it requires more maintenance to prevent weather-related damage.
  8. Insulated Window Frames: Beyond the glass itself, choosing windows with insulated frames can significantly boost overall energy efficiency.
  9. Energy Star Certified Windows: When selecting windows, it’s advisable to seek those certified by Energy Star, as they adhere to rigorous energy efficiency standards established by the U.S. Environmental Protection Agency.
  10. Spectrally Selective Coatings: These coatings can block certain wavelengths of light (like infrared) while letting others through, reducing heat without sacrificing natural light.

When selecting windows, consider not just the glass but also the framing materials and the overall design. The best choice of window for you will depend on your climate, your home’s design, and your specific needs.
