This is the last of the ongoing series from Hunter Douglas™ “We Make Green Beautiful” promotions.
Out planet gets an enormous amount of energy (solar) from our sun. In the summer, people do not want the dynamic energy entering our houses to become heat. That is why if you live in a hot climate, or anywhere the spring and summer is baking your house, you need a window treatment that will effectively reduce the solar heat gain from the sun.
The Coefficient for Solar Heat Gain
A coefficient from 0-1 is how solar heat gain is measured and that tells us what fraction of the suns energy hitting your window actually makes it into your house. The lower the number, the better for you. A standard window (double paned) will have a heat gain coefficient of around a .76. That means basically that seventy six percent of the solar energy (heat) makes it though and into your house. Most window covering products by Hunter Douglas™ reduce that amount dramatically. For instance, if you add the Luminette™ Privacy Sheers to that opening, that number will drop to as low as a .2 meaning only twenty percent makes it in. Now that’s dramatic. It not only blocks the heat but saves on electricity and money.
Just the opposite in the Winter
In the fall and winter, to bring down the heating energy consumption, you need to take advantage of as much free heat the sun can give you. You need to raise the shades whenever direct sunlight is shining and it doesn’t matter if it is cold out or not. For east windows, do this in the morning. For your west windows, in the afternoon and most of the day for your south windows.
