Choosing the Right Replacement Windows & Doors for Southern California’s Climate

Southern California homeowner’s considering more energy efficient replacement windows and doors should choose products with a lower Solar Heat Gain Coefficient, also known as the SHGC.

According to Energy Star, southern California is considered a South-Central Zone. Basically, what that means is we have one of the best climates in the world and everybody else is jealous of us. From a more conservative standpoint, our climate does experience a good amount of heat. Through extensive testing and research the National Fenestration Rating Council has determined that windows and doors with a lower Solar Heat Gain Coefficient are best designed for this climate. Simply put, SHGC is measurement of the heat that is blocked by the window or door. It is expressed as a ratio; 1 being 100% transference, and 0 being no transference. For example, an SHGC rating of a .30 allows 30% of heat to transfer through the window or door and into the home.

NFRC label

In addition to purchasing windows and doors that have a low SHGC, you will also want a low U-Value. The U-value measures heat loss through a window or door, according to the National Fenestration Rating Council.  Purchasing energy efficient windows and doors with a lower U-Value will help to reduce your heating costs during the colder months of the year. Like the SHGC, the U-value is also expressed as a ratio. A .30 U-Value means 30% of heat it lost through the window or door.

If a product has been certified by the NFRC, it will have a label on it like the one to the right. This label, for lack of a better term, is like a thermal fingerprint of that specific window or door. Each rating is specific to the make-up and size of that window or door.

With the cost of energy continuing to rise, having the most energy efficient windows in your home is one of the better investments you can add to your home.  Replacing your old single pane windows and doors with energy efficient ones can save you up to $501.00 per year, according to Energy Star.

Consider the following: You are paying your energy bill each and every day.  Whether you buy new energy efficient windows and doors today or tomorrow, you are paying for them!
