If it’s time to install new windows on your home, one thing to become familiar with is the r-value. The r-value indicates how much heat is prevented from passing through the panes of glass in a window. If purchasing windows having three panes, heat will take longer to pass through the glass, meaning that your home can be kept warmer for longer.
Window glass that has low-emissive coatings is a type often used by homeowners living in warmer climates. These coatings are available in a transparent film which is put on the window’s glass panes. Gas-filled windows are another alternative.
