Frequently Asked Questions:

  • Do Champion Windows meet Energy Star 7.0 requirements?

    Yes, Champion Windows meet Energy Star 7.0 requirements. Champion's enhanced Comfort 365 Windows® achieve the new Energy Star® 7 requirements, meaning they are more energy-efficient than ever before. With triple-pane glass, a low-emissivity (low-E) coating, argon gas filling, and a warm-edge spacer system, Champion Comfort 365 Windows® can help you save money on your utility bills and make your home more comfortable.

  • Why is it important to have energy efficient windows and doors?

    Energy-efficient windows and doors can help you save money on your energy bills, make your home more comfortable, and reduce your environmental impact.

    Saves money on energy bills: Energy-efficient windows and doors can help you save money on your energy bills by reducing the amount of energy you need to heat and cool your home.

    Makes your home more comfortable: Energy-efficient windows and doors can help keep your home cooler in the summer and warmer in the winter, making it more comfortable for you and your family.

    Reduces your environmental impact: Energy-efficient windows and doors can help reduce your carbon footprint and protect the environment by reducing the amount of energy you need to consume.

    In addition to these benefits, energy-efficient windows and doors can also increase the value of your home and improve indoor air quality.

  • How can I be sure my entry doors are energy efficient?

    To be sure your entry doors are energy efficient, look for doors with the following features:

    • Energy Star certification: Energy Star certified doors meet strict energy efficiency standards set by the U.S. government.

    • Insulated core: An insulated core helps to prevent heat transfer, keeping your home cooler in the summer and warmer in the winter.

    • Low-emissivity (low-E) coating: A low-E coating on the glass helps to reflect heat away from your home in the summer and trap heat inside your home in the winter.

    • Weatherstripping and sweeps: Weatherstripping and sweeps help to seal the gaps around your door, preventing air leaks.

    You can also ask your door dealer about the energy efficiency ratings of the doors they sell. The U-factor and solar heat gain coefficient (SHGC) are two important ratings to consider. The lower the U-factor, the better the door's insulation value. The lower the SHGC, the less heat the door will transmit.

  • How can windows protect the inside of my home from the sun?

    Windows can protect the inside of your home from the sun in a number of ways:

    • Block UV rays: UV rays from the sun can damage furniture, carpets, and other belongings in your home. Energy-efficient windows with a low-emissivity (low-E) coating can block UV rays, protecting your belongings from fading and discoloration.

    • Reduce heat gain: Windows can let in a lot of heat from the sun, which can make your home uncomfortable and increase your energy bills. Energy-efficient windows with a low solar heat gain coefficient (SHGC) can help to reduce heat gain, keeping your home cooler and more comfortable in the summer.

    • Control glare: Glare from the sun can make it difficult to see and can be uncomfortable. Energy-efficient windows with tinted glass can help to reduce glare, making your home more comfortable and enjoyable.

  • How do I choose the best company for my energy efficient windows and doors?

    When choosing a company to install your energy-efficient windows and doors, there are a few things to keep in mind:

    • Reputation: Choose a company with a good reputation. You can ask for recommendations from friends and family, or read online reviews.

    • Experience: Make sure the company has experience installing energy-efficient windows and doors. Ask about the company's training and certification programs.

    • Warranty: Choose a company that offers a good warranty on its products and workmanship.

    • Price: Compare prices from different companies before making a decision. Keep in mind that the cheapest company may not be the best value.

  • How much do energy efficient windows cost?

    The cost of energy-efficient windows can vary widely depending on various factors such as the brand, materials used, features, and the size of the windows. Generally, you can expect to pay more for windows with advanced features like triple-pane glass, low-emissivity (Low-E) coating, and argon gas filling, as you find in Champion Comfort 365 Windows®.

    It's essential to consider that while the initial cost may be higher compared to standard windows, energy-efficient windows are an investment that can save you money in the long run through reduced energy bills. According to the U.S. Department of Energy, replacing old windows with Energy Star® certified windows can save you between $126 to $465 a year depending on your region and the number of windows you replace. To get an accurate quote tailored to your needs, it is best to consult with a reputable provider. Champion, for instance, offers a variety of energy-efficient options designed to fit different budgets and requirements, while also meeting Energy Star 7.0 standards for maximum efficiency.
