Airtite Sunscreens


The Affordable Exterior Shading
Replaces regular insect screening... Sun Screen solar screening is a leading choice for sun control among architects, builders, and homeowners. Unlike interior window treatments, like drapes, blinds or even double glazing (which can absorb and then reradiate the sun's heat), SunScreen absorbs and dissipates up to 70 percent of the sun's heat and glare before it reaches the window.


In diagram 1, at 40deg N. latitude in mid-summer, as much as 230 Btu can fall on each square ft. of window glass. Although 44 Btu are reflected away by the 1/4" clear plate glass, 186 Btu penetrate into the workspace.

In diagram 2, adding a solar screen makes a huge difference. Of original 230 Btu, 28 are reflected away by the screen, 138 are absorbed and dissipated. Only 64 reach the glass and only 52 pass through into the exterior space.

SunScreen solar 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.

SunScreen solar screens save energy... SunScreen solar screens offer an easy and practical method for improving the energy efficiency of windows and glass doors.

In the summer, most unwanted heat gain 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 (5.5 M2) of glass can admit as much as 12,000 BTU of heat each hour, requiring one extra ton of air conditioning 9 East facing, 8 a.m., Latitude 40 degrees N.)

Controlling this solar heat is extremely important in energy conservation and passive solar design.

Phiferglass® SunScreen is a specially woven exterior solar screen that blocks up to 90 percent of the sun's heat and glare before it reaches the glass surface
