Window shades are not an original concept. The concept has been in use since ancient times. A piece of light material is used to as a removable cover to protect the home or a building from the heat of the sun.
However, what solar shades offer is a different take on how shades can be improved and the concept updated for the 21st century. As explained by lhpinc.com, the difference is fundamental and out of the box.
Keeping the Heat In
The use of window shades has traditionally been from the inside a window. This is especially true if the window is made of glass. The biggest part of the shade is the fabric which is rated according to openness. Openness describes how much of the sun’s rays the fabric allows. A high openness factor equivalent to 11% to 14% helps reduce glare and allows for the best visibility. Medium openness of 7% to 10% provides the view as well as protection from UV rays. Low openness of 3% to 5% blocks more of the sunlight and affords greater privacy, as well as blocking most of the view.
Traditional window shades can be raised or lowered by pulling it up, with the use of a cranking mechanism, or with remote control. Studies show that a home loses approximately 25% of its heat through the windows. Blinds and shades help keep the heat in by serving as a barrier between the room’s air and the window.
Keeping the Heat Out
There are also circumstances when it would help to keep the heat out. This is done by installing the shades outside of the window. In this manner, the shades absorb sunlight and the heat, before it hits the glass window. It’s the same effect as the indoor shades. External shades also work well with covered patios, in keeping the area cool.
