Efficient Windows and Doors
High-efficiency windows increase comfort and cut energy use. Single-pane windows are inefficient compared with newer double- and even triple-paned windows. Between the panes are inert gases that add to the window’s insulation. The more panes, the more protection from the cold, with the interior glass staying the warmest. Insulation of the window frame. The window frame conducts heat that contributes to a window’s overall energy efficiency, particularly its u-factor. That measures the amount of heat loss a window permits. The lower the u-factor, the greater a window’s resistance to heat flow and the better its insulating properties. Reflective material coating the glass. Low-E coatings keep out the summer heat and act like sunscreen for your house. They reflect heat and protect your valuables from harmful, fading ultraviolet light without noticeably reducing visible light. The special coating can reduce fading by up to 75 percent. Does your monthly utility bill seem much higher than it should be? Would you like your home to be warmer in the winter and cooler in the summer? Have you noticed condensation on your windows, or do they stick when you try to open or close them? Replacement windows are one way to spruce up your home’s appearance. They can also make your house more energy-efficient.
