    3 Factors That Make Windows Energy-Efficient

    When it comes to windows installation or replacement, most homeowners want something that can help them save energy costs. Hence, if you’re aiming for energy-efficient windows, you must know what makes them energy-efficient. This way, you’ll understand the value of each material you’ll be using.

    1. Glass

    Plain glass doesn’t help very much in protecting your home from ultraviolet (UV) rays that can cause adverse effects, such as faded carpets and furnishings. With only plain glass, your heater and air conditioner will work double-time to keep your house comfortable, thus resulting in higher energy costs.

    To maximize the performance of your replacement windows, opt for low-E glass, such as the Renewal by Andersen® High Performance™ Low-E4® glass. Compared to regular dual-pane glass, it is 56% more efficient during summer and 47% more efficient during winter.

    2. Glazing

    In terms of glazing, tinted and transparent glazings (or coatings) efficiently help in preventing heat, cold and sunlight from entering your home.

    3. Gas

    An insulating unit that is filled with gas is an excellent seal. It acts as an excellent barrier against heat gain or loss. A gas-filled insulating unit is an excellent barrier.

    For energy-efficient windows, the best choice is an insulated glass unit (IGU). This consists of at least two pieces of annealed glass bound together with a thermal spacer. The thermal spacer of an IGU is filled with either argon or krypton gas.

    This odorless and nontoxic gas becomes an invisible barrier to stop UV rays and extreme temperatures from seeping inside. An IGU also work the other way, helping lock in climate-controlled air and preventing leaks to the outside. This will lower your energy bills because your HVAC system won’t have to work as hard to maintain your internal temperature.
