Benefit from Energy Star Rated Replacement Windows in Southern California’s Climate

Energy Star has divided the US into four climatic zones. In this map, Southern California comes under the South Central Zone. What it basically means is that the climate in Southern California is one of the best in the world. Even so, some Southern California cities such as Riverside, Fontana, Redlands, Ontario, Moreno Valley, Perris, San Bernardino and Palm Springs can experience extremely hot weather in the summer and very cold weather in the winter.

Energy Star Rating - Climate Zone Map - Windows

Research by the National Fenestration Rating Council has found that the best kind of windows for the South Californian climate are those which transfer a low amount of heat such as dual pane insulated windows. These energy efficient windows should also have a low U-Value rating. The U-Value measures how much heat a window allows to escape. Replacement windows have both low SHGC (Solar Heat Gain Coefficient) and U-Values. So, these windows can also help you lower your heating bills in winter.

Why Replacement Windows Are Better Than Your Old Windows

Your old windows can lose heat to the outdoors during winters and gain heat during summers. Energy Star rated energy efficient replacement windows are excellent insulators. For example, new insulated windows can insulate 1800 times more when compared to some older windows. Insulated replacement windows contain double or triple glass panes. The space between the glass panes is filled with an insulating gas such as argon, which will maximize the windows’ heating efficiency.

In the summer, these windows can bear high temperatures without bowing or warping. The glass is coated with a special polymer window coating which reflects the sun’s heat away from your home, keeping the interior cool.
