  • Air leakage – this is the amount of air allowed to filter in or out of the dwelling from around the window frame or the window itself. It is measured in cubic feet per minute, per square foot of window area (including frame). The lower the rating, the tighter the window, consequently – the higher the efficiency.
  • U-Factor is the rating of how much heat or cold is transmitted through the window panes or glazing. A variation of this rating is the National Fenestration Rating Council U-Factor, which includes the framing and spacer material for an overall rating. The lower the rating, the higher the efficiency of the window.
  • Solar heat gain coefficient (SHGC) – is the amount of heat that is radiated into a room by direct sunlight entering the window, allowing heat to radiate from surfaces in the room. The lower the rating, the lower the amount of solar heating effect. Windows are available with intentional higher or lower SHGC ratings for different uses. Windows with a higher SHGC rating are good for winter solar heat on sides of a home with solar exposure, whereas windows with a low SHGC rating help keep the exposed sides of the home cooler in summer. One way to change this rating on any window is with window tinting. The addition of window film on the glass panes acts as a shade which reduces solar radiation.

  • Remove any remaining debris or protruding nails, so that the rough opening is clean and flush.
  • Place new window in opening; adjust so it is centered. Check to make sure window is level, plumb, and square. Windows that are out of square will not operate properly. Use cedar shims to center and level the window. Most new windows have a pre-drilled nailing strip; use 1 ½ inch to 2-inch galvanized roofing nails to secure the window to the nailing flanges in the opening. Space nails 6 to 8-inches, or about every other pre-drilled hole in the strip.
