What makes a window energy-efficient? It is without a doubt that installing an energy-efficient window in your home is a smart investment. Energy-efficient windows are cost-effective, playing a role in improving your home’s energy performance. Reliable siding and window professional Hunterdon Roofing, Siding and Window Company break down the elements of an energy-efficient window.
Advancements in window technology over the last 25 years have made it possible to design windows that save energy. Compared to old traditional windows, energy-efficient windows provide better insulation for a home. Here are some of the elements that make a window energy-efficient.
Low emissivity or Low-E glass has transparent coating that minimizes the amount of heat passing through the glass without blocking the natural light. The coating reduces the U-value of the glass that measures the window’s prevention of non-solar heat loss or gain. A low U-value means the window’s insulation and resistance to heat flow are good.
High-quality window seals are important to make an energy-efficient window. With good window seals, the conditioned air inside your home would not be able to escape. This helps the energy-efficient windows to insulate better compared to traditional windows. To save money from high energy bills, it’s best to switch to energy-saving windows. For windows and siding replacement services, make sure to hire a trusted local contractor.
Double Glazed Windows
Double glazed windows are also known as high-performance windows. It is the best in thermal performance with Low-E glass and Argon gas in between. The U-value can be low as 1.8, almost three times lower than a single-glazed window. Window frames complete energy-efficient windows. The low U-value frames complement the glazing system. Usually, the frames are manufactured using timber, uPVC, or a composite aluminum/timber design.
