Anyone who pays special attention to their surroundings have most likely seen the Energy Star Symbol. This symbol is found everywhere from homes and schools to fortune 500 companies. Its seems to be on everything from qualified fax machines to furnaces.
The average window has really taken a step forward from where it began. From the first glass window, most likely used by the Romans around 100 AD to the windows made out of flattened animal horns in the 14th century or paper windows used in China, Korea and Japan. It wasn’t until the early 17th century that glass window panes became a common use. As we progressed through time, our windows started developing into more than just an opening to let light and/or air into our homes. Windows became a stylish decision when building or decorating our homes and offices. We would decide on which direction we want our houses to face dependant on which way the sun faces us in regards to how big or where the window is placed.
In 1998, the Energy Star Symbol was added to windows that met the criteria set out by National Fenestration Rating Council (NFRC). By installing Energy Star windows, for the first time or using them to replace your old windows we have created an environment that has brought security and comfortability to our homes and offices. We don’t need to curl up in blankets and sweaters or block sunlight with strange designs we’ve conjured up such as tinfoil over the windows or plastic wraps heated to the frame. With eliminating cold drafts or choosing how much sunlight we allow in, we now regulate the homes temperature. Energy Star certified windows lower the household energy bills by an average of 12% nationwide and brings a piece of mind knowing we are reducing our carbon footprint.
We do this by testing each window against five categories set out by the National Fenestration Rating Council (NFRC).
U-Factor: Measures the rate of heat transfer and tells you how well the window insulates.
Solar Heat Gain Coefficient (SHGC): Measures the fraction of solar energy transmitted and tells you how well the product blocks heat caused by sunlight
Air Leakage (AL): Measures the rate at which air passes through joints in the window. AL is measured in cubic feet of air passing through one square foot of window area per minute
Visible Transmittance (VT): Measures the amount of light the window lets through
Condensation Resistance: Measures how well the window resists water build-up

There is also the added bonus of knowing that low-emissivity coatings on many of the windows reduces UV sun damage to floors, carpets and furniture which keeps our rooms looking newer for longer.
Regardless of the details of picking a window that’s right for you, we are more than pleased to offer a variety of Energy Star products to improve the look and feel of your home.
