If You’re Buying Windows Make Sure They Are 7.0 Energy Star Rated.

Energy Star windows with a rating of 7.0 or lower in U-factor can offer several benefits:

Federal Tax Credit

Energy Efficiency

Windows with a lower U-factor provide better insulation, reducing the transfer of heat between the interior and exterior of a building. This can lead to lower heating and cooling costs throughout the year, as the windows help maintain a more stable indoor temperature.

Improved Comfort

By reducing heat transfer, Energy Star windows can help maintain a more consistent indoor temperature, reducing hot and cold spots near windows. This can lead to increased comfort for occupants, especially in areas with extreme temperatures.

UV Protection

Energy Star windows are designed to reduce the transmission of ultraviolet (UV) rays, which can cause fading and damage to furniture, flooring, and other interior surfaces. By blocking UV rays, these windows help preserve the appearance and longevity of interior furnishings.

Condensation Reduction

High-quality windows with low U-factors are less prone to condensation buildup, which can lead to mold, mildew, and moisture damage. Energy Star windows can help minimize condensation on window surfaces, improving indoor air quality and reducing the risk of related issues.

Environmental Impact

By reducing energy consumption for heating and cooling, Energy Star windows can lower greenhouse gas emissions associated with energy production. This helps reduce the environmental impact of buildings and contributes to sustainability efforts.

Potential Cost Savings

While Energy Star windows may have a higher upfront cost compared to standard windows, the energy savings they provide over time can offset this initial investment. In many cases, homeowners or building owners can recoup the additional cost of Energy Star windows through reduced energy bills over the life of the windows.

Increased Property Value

Energy-efficient upgrades, such as Energy Star windows, can enhance the value of a property. Potential buyers may be willing to pay more for a home or building with energy-efficient features that offer long-term savings on energy costs.

What is the best window for your climate?

What window climate zone do you live in and why it matters.

  • U Factor and SHGC Ratings: Different climate zones experience varying degrees of temperature extremes throughout the year. In colder climates, windows need to provide better insulation to minimize heat loss and keep the interior warm during winter months. In warmer climates, windows should have properties that reduce heat gain to keep the interior cool during hot summer months. Therefore, the U-factor and Solar Heat Gain Coefficient (SHGC) ratings of windows should be chosen based on the specific climate zone to maximize energy efficiency.
  • Comfort: Windows that are appropriately designed for the local climate can contribute to a more comfortable indoor environment. In colder climates, efficient windows help prevent drafts and cold spots near windows, while in warmer climates, they can help reduce the need for excessive air conditioning by blocking unwanted heat from entering the building.
  • Condensation: Climate conditions can also affect the likelihood of condensation forming on windows. In cold climates, windows with low U-factors are essential to reduce the potential for condensation buildup on the interior surface of windows, which can lead to mold, mildew, and moisture damage.
  • Durability: Exposure to different climate conditions, such as extreme temperatures, high humidity, or salt air in coastal areas, can impact the durability and performance of windows over time. Choosing windows specifically designed to withstand the environmental challenges of a particular climate zone can help ensure their longevity and reduce maintenance costs.
  • Building Codes: Building codes and regulations may also vary depending on the climate zone. Some regions may have specific requirements or recommendations for window performance to meet energy efficiency standards or withstand weather-related risks such as hurricanes or earthquakes.

By considering the climate zone when buying windows, homeowners and builders can select products that are optimized for the local climate conditions, leading to improved energy efficiency, comfort, durability, and compliance with building codes and regulations.

How long does the installation process take?

Many factors play into this, including the size of the project and the type of product being installed. An average house has 10-25 windows of all shapes, sizes, and compositions, and a large window replacement job may take 2-5 days. Most door installations, on the other hand, can be completed same-day. Give us a call to discuss the specifics of your project and get a more accurate timeline.
