Solar Screening
THE AFFORDABLE EXTERIOR SHADING
Replaces regular insect screening…
If you live in California, the land of the sun, solar window screening is of vital importance to you for your health and your electric bill. Solarscreening is a leading choice for sun controlamong architects, builders and homeowners. Unlike interior window treatments, such as drapes, blinds or even double blazing (which can absorb and then re-radiate the sun’s heat), Solar window screening absorbs and dissipates up to 70 percent of the sun’s heat and glare before it reaches the window or door.
Window sun screens cost less than most other sun shading methods, and as a result, usually show a much shorter payback period. They are easily installed on any type and size of window and may be removed and stored if full heat gain is wanted during winter months.
Solar screens for windows and doors save energy…
Sun Screen solar screens offer an easy and practical method for improving the energy efficiency of windows and glass doors.
In the summer, most unwanted heat comes in the form of sunlight radiating through unprotected glass. This glass is a building’s most vulnerable area for heat gain. In fact, 60 square feet (5.5M squared) of glass can admit as much as 12,000 Btu of heat each hour, requiring one extra ton of air conditioning (East Facing, 8 a.m., Latitude 40degrees N.) Controlling this solar heat is extremely important in energy conservation and passive solar design. Phiferglass SunScreen is specially woven for exterior solar sun screens that blocks 70 percent of the sun’s heat and glare before it reaches the glass surface.
In Diagram 1 , at 40 degrees N. latitude in mid-summer, as much as 230 Btu can fall on each square foot of window glass. Although 44 Btu are reflected away by the 1/4” clear plate glass, 186 Btu penetrate into the work space.
In Diagram 2, adding solar window screening makes a big difference. Of original 230 Btu, 28 are reflected away by the screen, 138 are absorbed and dissipated, only 64 reach glass and only 52 pass through into interior space.
