Windows have the lowest insulation value of any element in a building and are therefore responsible for the greatest energy loss. 50% of the solar heat that enters a room comes through the glass while 40% of the heat that escapes leaves through it.
Transparent solar shades significantly reduce the high cost of energy consumption for cooling and heating without sacrificing outward visibility. They maintain the open feeling of looking out. Because they quickly pay for themselves, with skyrocketing fuel costs they are like putting money in the bank.
Solar shades are a transparent woven material. They come in different densities or openness factors. The tighter the weave, the more heat that is rejected because light causes heat when it hits something solid and converts to heat energy.
Exterior Solar Shades are the best defense against the heat. They started in Europe as a way to keep buildings cool. Because they absorb the solar radiation before it passes through and needs to be reflected out, they keep the interior much cooler. Darker colors on the exterior absorb more light and are therefore 10% more effective than light colors against the heat. The tighter the weave, the more sun they block and therefore the cooler you are on the inside.
Interior Solar Shades form an insulating air pocket between the shade and the window. Our high performance solar shades are enhanced with a layer of aluminum on the outside facing side to maximize heat rejection. You can use any color on the inside and still get maximum heat rejection. This is also great because darker colors give sharper outward visibility and better glare reduction. High performance solar shades actually stop more heat than a regular white shade.
If you don’t want the aluminum on the outside facing side, white or colors closest to it reflect the most heat back out through the glass in the summer. For instance, you will notice If you put your hand on a black car and a white car, the white car is always cooler. Again, tighter weaves will give more heat reduction because light causes heat. In the winter shades should be raised during the day to allow in the sun’s radiation. At night in the winter or on cloudy days they should be lowered to reflect heat back into the room.
